Costa Rica’s Southern Zone is a perfect mix of stunning Pacific beaches, misty mountains, and authentic towns still untouched by mass tourism. While many visitors to Costa Rica stick to the popular destinations in Guanacaste or the Central Valley, if you venture south you’ll be rewarded with fewer crowds, lower prices, and some of the country’s most breathtaking scenery.
The journey through this region takes you from the surfing beaches of Dominical to the large commercial center of San Isidro de El General. Further south you’ll find the indigenous heartland around Buenos Aires. Along the way, you’ll drive through mountains where pine trees and palms can be seen within a single hour’s drive. Pass by countless rivers flowing from the mountains and spot roadside sodas serving up delicious casados for a fraction of resort prices.

Exploring Costa Rica’s Southern Zone
Where is the Southern Zone?
The Southern Zone of Costa Rica runs along the Pacific coast and inland mountains south of the Central Valley. This region stretches from Manuel Antonio and Dominical down to the Panamanian border, including both coastal areas and the interior highlands. Unlike the more developed northern Pacific region of Guanacaste, the Southern Zone maintains a rawer, less commercialized feel that many travelers find refreshing.
To reach this region, you’ll likely start at San José International Airport. From there, you’ll head south over what locals sometimes call the “winding Hill of Death” (don’t worry, it’s just a dramatic name for the mountain pass). The drive from San José to San Isidro takes about 3 hours, while continuing to Dominical on the coast adds another hour. If you’re heading to Buenos Aires, you’ll drive about 4 hours from San José through agricultural lands and indigenous territories.
What makes the Southern Zone unique is how quickly the landscape changes. Within a single hour’s drive, you can go from cool mountain pine forests to hot, humid coastal jungles. The region is home to the Talamanca Mountain Range, which is the backbone of southern Costa Rica and creates dramatic valleys, rivers, and microclimates throughout the area.
When to Visit the Southern Zone
The Southern Zone has distinct weather patterns that differ from other parts of Costa Rica. The dry season runs from December through April, offering sunny days perfect for beach activities in Dominical and easier driving conditions on mountain roads. January and February tend to be the busiest months, though even then, this region sees far fewer tourists than Guanacaste or Manuel Antonio.
Rainy season (or “green season”) runs from May through November, with September and October typically seeing the heaviest rainfall. During these months, expect afternoon downpours that can make mountain roads more challenging.
However, mornings are often clear, and the landscapes turn incredibly lush. The rain also brings out wildlife and creates powerful waterfalls throughout the region. If you visit during these months, plan outdoor activities for morning hours and keep flexible afternoon plans.
Temperature varies dramatically with elevation in the Southern Zone. Coastal Dominical stays hot year-round (around 27-32°C). San Isidro at 2,300 feet elevation enjoys a pleasant “eternal spring” climate with temperatures between 18-27°C. As you climb the mountains between towns, temperatures can drop significantly, so pack layers if you plan to explore different elevations. Many visitors notice the temperature change immediately when driving through this region – you’ll feel the humidity and heat hit you suddenly as you descend from the mountains toward the coast.

Dominical: Surf Town by the Pacific
Dominical has a way of sticking with you. Arriving after winding down from the mountains, you’re immediately greeted by that distinct coastal heat and humidity. This small beach town consists of one main road running towards powerful waves breaking on a dark sand beach. You won’t find major resorts here. Instead, Dominical has a mix of surf shops, family owned restaurants, and a diverse crowd. Surfers, travelers, and local families enjoying the Pacific shore.
The town has grown gradually over the years without losing its character. The addition of the BM supermarket outside town is a welcome convenience for stays of more than a day or two. Vendors still set up along the beach road daily, selling handcrafted items, jewelry, and clothing. What makes Dominical truly special is the dramatic backdrop – surfing here means looking up at green mountains that rise sharply from the coastline, creating a striking contrast between ocean blue and jungle green.
Getting to Dominical
Two routes lead to Dominical, each having different experiences. From San José, take Highway 27 west toward Jacó, then turn south on Highway 34 along the coast. This journey typically takes about 3.5 hours on well maintained roads, with pleasant ocean views accompanying the southern portion of the drive.
The mountain route from San Isidro is a more scenic ride. This winding road takes you through the highlands and small towns like Tinamastes and Platanillo, with the climate changing noticeably as you descend. The temperature starts cooler in San Isidro, then gradually warms as you approach the coast. Several lookout points along the way provide panoramic views of the coastline on clear days. The drive is roughly 45 minutes without stops, but allowing time for viewpoints is worthwhile.
Upon reaching Dominical, navigation becomes simple. The town spans just a few blocks, making it entirely walkable. Parking can become challenging during peak season, especially on weekends when visitors from nearby towns arrive for beach days.
Top Activities in Dominical
Surfing is Dominical’s primary draw. The consistent waves have built the town’s reputation among surf enthusiasts. The main beach has stronger breaks that attract experienced surfers, while beginners find more forgiving conditions slightly north of town. Several schools offer lessons ranging from $50-60, with instructors providing hands on guidance to newcomers.
The beach itself deserves attention even for non-surfers. While not the pristine white sand type found in travel brochures, Dominical’s shoreline has its own character. At low tide, natural rock pools form to the south end, creating safe areas for children to enjoy the water away from the powerful waves. The addition of lifeguards during busy periods provides essential safety given the strong currents.
Wildlife viewing opportunities are both in and around town. You can occasionally spot sloths in trees near the beach area, particularly after rain showers. The nearby Hacienda Barú wildlife refuge offers more structured nature experiences, and whale watching tours operate during migration seasons (December-April and July-November), providing opportunities to observe these magnificent marine mammals in their natural habitat.
Mountain Routes: The Drive to San Isidro
The mountain roads connecting the Pacific coast to San Isidro de El General offer some of Costa Rica’s most dramatic scenery. This route takes you from sea level up through cloud forests and back down into a fertile valley, with the landscape changing dramatically as you climb. It’s not just transportation—it’s an experience that gives you a true sense of Costa Rica’s diverse microclimates and topography.
Route Options and Road Conditions
The main route between Dominical and San Isidro follows Highway 243 up from the coast through Platanillo and Tinamastes before connecting with Highway 2 into San Isidro. The road is fully paved but extremely winding as it navigates the mountainous terrain. Road conditions are generally good, though heavy rains during green season (May-November) can occasionally cause delays from minor landslides or fallen trees.
Driving these mountain roads requires heightened attention. Drivers often pass on blind corners or rush up behind slower vehicles. It’s best to drive defensively, use turnouts when available to let faster traffic pass, and keep to your lane on curves. The drive includes several one-lane bridges where you’ll need to yield to oncoming traffic if you see the “CEDA” (yield) sign. Rental car agencies typically recommend SUVs for this region, though standard vehicles can manage during dry season.
The journey includes several notable stops. About halfway between Dominical and San Isidro, you’ll find viewpoints where, on clear days, you can see all the way to the Pacific Ocean. These spots often have small cafes or fruit stands selling fresh produce and coffee. The town of Tinamastes has a popular farmers market on Tuesdays, worth timing your drive to experience local produce, crafts, and organic products.
Stunning Mountain Views
What makes this drive truly special are the panoramic vistas that appear around seemingly every bend. As you climb from the coast, you’ll reach viewpoints at about 3,000 feet elevation that have sweeping views of the coastline stretching north and south.
The changes in vegetation as you climb are remarkable. Starting with coastal palm trees and tropical flora near Dominical, you’ll transition through dense rainforest mid-mountain, and in the highest parts of the drive, you might be surprised to see pine trees and other highland vegetation. The temperature drops noticeably with each thousand feet of elevation gain—plan to feel a 10-15°F difference between Dominical and the highest point of your journey.
Weather changes quickly in these mountains. You might start in sunshine on the coast, drive through clouds or rain mid-mountain, and emerge into sunshine again on the other side. This creates stunning light conditions for photography, particularly in the morning when mist often hangs in the valleys between mountain ridges.
This is one stop that has a nice elevated lookout towards the Pacific Ocean. There’s a small restaurant and fruit market here as well.
Small Towns Along the Way
Several small communities dot the mountain route, each with its own character. Platanillo serves as the first significant settlement as you climb from Dominical, offering a few local restaurants and basic services. It’s a good spot to fuel up before tackling the mountain roads.
Tinamastes has developed into something of a hub for organic farming and sustainable living. Besides its Tuesday market, you’ll find several eco-friendly businesses, organic cafés, and retreats. The town attracts both expats and Costa Ricans interested in alternative lifestyles, creating an interesting cultural blend.
Further along, the road passes by the entrance to Nauyaca Waterfall, one of the region’s most impressive natural attractions. A 4km hike (or horseback ride) leads to twin cascades with a natural swimming pool—well worth the detour if you have half a day to spare. Several tour companies in Dominical offer guided excursions, or you can visit independently for a small entrance fee.
As you approach San Isidro, the landscape opens up into a wide agricultural valley surrounded by mountains on all sides. Small farms and ranches line the roadside, with cattle grazing on impossibly steep hillsides—a testament to the resourcefulness of local farmers who have adapted their agricultural practices to this challenging terrain.
San Isidro de El General
San Isidro de El General is the commercial center of Costa Rica’s Southern Zone. Unlike tourism focused coastal towns, San Isidro is a working city where locals outnumber visitors. This gives you a more authentic experience for Costa Rica. You’ll find stocked markets, local eateries, and a non-touristy atmosphere.
Located at about 700 meters in elevation, it’s in a valley surrounded by mountains, so the climate here is fairly consistant and cooler than the coast. Daytime temperatures typically range from 21-29°C, so it’s comfortable to explore on foot all year round. The central area is organized in a grid pattern, with the main commercial district stretching about 10 blocks in each direction from the central park and church.
The Commercial Hub of the South
San Isidro functions as the primary service center for the entire Southern Zone. Locals from surrounding towns and rural areas come here for everything from banking and medical care to shopping and government services. You’ll find practical resources here too, including supermarkets, hardware stores, automotive services, and regional bus connections.
The downtown area centers around the main park (Parque Central) and the blue church (Iglesia de San Isidro Labrador) that anchors the city. From this central point, you’ll see banks with ATMs, pharmacies, clothing stores, and numerous sodas (small local restaurants). Several major supermarkets, including Maxi Pali and BM, have wider selections than you’ll find in coastal towns. For import selection visit the Luferz Supermarket which is on the main highway at the McDonald’s intersection.
If you need to resupply, repair equipment, or access services, San Isidro has everything you might need during your journey through the Southern Zone. Many people use the city as a base for exploring the region or as a stopover when traveling between the coast and San José. Hotel options range from simple hostels to mid-range business hotels, most with good value compared to tourist areas.
Local Markets and Shopping
The Municipal Market (Mercado Municipal) is San Isidro’s commercial primary commercial destination. This indoor market has dozens of small vendors selling fresh produce, meats, cheeses, spices, and prepared foods. It’s the perfect place to sample local specialties like chorreadas (corn pancakes), fresh fruit smoothies, or regional cheeses. The market runs daily but is busiest in the mornings and on weekends.
Every Thursday & Friday, the city has a farmers market (feria) where regional producers bring their goods directly to consumers. Here you’ll see an impressive variety of tropical fruits, many of which don’t appear in standard supermarkets. This is also an excellent opportunity to purchase local coffee directly from the families who grow it, often at better prices than elsewhere. This market is held in a large covered building near the main highway.
Shopping in San Isidro focuses on practical items rather than souvenirs, though you can find some artisanal products at the Mercado Municipal and various shops near the central park. Farther along the stretch of Highway #2, you’ll find more spread out shopping options like Walmart, CoopeAgri and some indoor malls.
Day Trips from San Isidro
San Isidro’s central location makes it an ideal base for exploring nearby attractions. To the west, the mountain route to Dominical leads to waterfall hikes, wildlife viewing, and beach access. Nauyaca Waterfall is about 40 minutes from the city.
Heading east takes you to Chirripó National Park, home to Costa Rica’s highest peak at 3,820 meters. For adventure seekers, the area has white water rafting options from family friendly Class II-III rapids to more challenging Class IV sections.
Several coffee farms around San Isidro allow you to learn about growing and processing Costa Rica’s famous coffee beans, providing insight into the agricultural foundation of the region’s economy.

Buenos Aires: Off the Tourist Trail
I drove into Buenos Aires after passing miles of pineapple fields, and immediately noticed how different it felt from coastal tourist towns. This agricultural hub is about 4 hours south of San José and 45 minutes south of San Isidro. You won’t find many international tourists here. Instead, the central park fills with local families in the evenings, small sodas serve cheap casados, and Spanish dominates both conversation and signage.
The town isn’t fancy – just a simple grid of streets around a central park with a church and municipal buildings. Prices reflect the local economy rather than tourist demand. You can expect to pay lower prices at restaurants, as compared to popular tourist towns like Uvita. The surrounding mountains create a dramatic backdrop, especially in the morning when clouds hang low over the ridges.
Indigenous Culture and History
Buenos Aires borders several indigenous territories, including the Boruca and Térraba reservations. These communities have maintained their cultural practices despite centuries of outside pressure. In the town park, you’ll notice distinctive round stones created by pre-Columbian indigenous peoples – similar stones appear throughout the Southern Zone.
The indigenous lands house natural springs and rivers flowing from the mountains. When I visited a hot springs in the indigenous territory, I met the owner Arnold who manages the property. It had both hot and cold pools fed by natural springs. We picked lemons growing on trees around the property and squeezed them into our drinking water – a simple experience that felt worlds away from commercial tourist attractions.
If you’re here in late December or early January, try to catch the Juego de los Diablitos (Game of the Little Devils) celebration by the Boruca people. Local men wear hand-carved masks representing “devils” (the indigenous people) who battle against a bull (representing Spanish colonizers). After days of ceremony, they burn the bull effigy, symbolizing indigenous resistance.
Hot Springs and Natural Attractions
The mountains around Buenos Aires contain several hot springs from the region’s geothermal activity. These aren’t developed resorts – most are simple pools with minimal facilities. The water temperatures vary between spots, but all offer a rustic bathing experience that costs a fraction of what you’d pay in tourist areas.
From town, you can see the slopes of the Talamanca Mountain Range, part of which forms Parque Internacional La Amistad spanning the Panama border. Rivers flowing down these mountains create small waterfalls and swimming holes throughout the area, many are listed on Google Maps but many aren’t. Exploring the area with a rental car is a great option.
The drive to Buenos Aires passes through extensive pineapple plantations – rows upon rows of spiky plants stretching to the horizon. Around town, small farms raise cattle, sugar cane, and various fruits. It’s amazing to see cattle grazing on hillsides so steep they seem to defy gravity. The farmers have adapted their techniques to this challenging terrain, clearing narrow paths that zigzag up the mountains.
If you want to experience Costa Rica beyond the tourist trail, Buenos Aires has a genuine look at rural life, indigenous heritage, and natural attractions that most visitors never see. It makes a perfect stopover when traveling between the Central Valley and points further south, or as a base for exploring the surrounding mountains.

Frequently Asked Questions
How long should I stay in the Southern Zone?
Plan for at least 4-5 days to properly experience the Southern Zone. This allows time for 1-2 days in Dominical for beach activities and surfing, 1 day for the mountain drive with stops at viewpoints and small towns, 1-2 days based in San Isidro to explore the valley and nearby attractions, and potentially a day trip to Buenos Aires if you’re interested in indigenous culture. You could spend a week or more in this region, using it as a base to explore attractions further south like the Osa Peninsula.
What’s the best time of year to visit the Southern Zone?
The dry season (December through April) has the most reliable weather for exploring the Southern Zone. January and February are ideal months with clear skies, though this is also peak tourist season. The shoulder seasons (May/June and November) can be good compromises, with fewer visitors and intermittent rain that typically falls in the afternoons. During the green season (July through October), morning activities are usually fine, but heavy afternoon rains are common.
Do I need a 4×4 vehicle to explore the Southern Zone?
While a standard vehicle can manage the main roads between Dominical, San Isidro, and Buenos Aires during the dry season, a 4×4 or high clearance vehicle provides more flexibility for exploring side roads and accessing natural attractions. During the rainy season (May-November), a 4×4 is strongly recommended, especially for mountain roads where landslides or washouts may occur. If you’re planning to visit indigenous territories or remote hot springs around Buenos Aires, a 4×4 is essential year-round.
Is the Southern Zone safe for travelers?
The Southern Zone is generally considered safe, with lower crime rates than more touristy destinations. Standard precautions apply: don’t leave valuables visible in parked cars, be cautious with belongings at beaches, and avoid isolated areas after dark. San Isidro and smaller towns have a strong local community presence, and violent crime targeting tourists is rare. The biggest safety concerns in this region tend to be related to road conditions, strong ocean currents in Dominical, and occasional flash flooding during heavy rains.
How does the Southern Zone compare to more popular destinations like Guanacaste?
The Southern Zone has a more authentic Costa Rican experience than heavily developed areas like Guanacaste. You’ll find fewer all-inclusive resorts, international restaurant chains, and organized tours, but more opportunities to interact with locals and experience daily Costa Rican life. Prices tend to be lower, crowds smaller, and natural attractions less commercialized. The beaches are less manicured but often more dramatic, with jungle-covered mountains at the shoreline. The climate is generally wetter than Guanacaste, resulting in more lush vegetation and varied ecosystems.
Can I get by with only English in the Southern Zone?
In tourist areas like Dominical, most businesses that cater to visitors have English-speaking staff. However, as you move inland to San Isidro and especially Buenos Aires, Spanish becomes increasingly important. Basic Spanish phrases for ordering food, asking directions, and handling transportation will significantly enhance your experience. In indigenous territories, some older residents may speak native languages in addition to Spanish.
What are the best food experiences in the Southern Zone?
Don’t miss the opportunity to try a traditional casado (a plate with rice, beans, plantains, salad, and your choice of protein) at local sodas, which have authentic food at reasonable prices. In San Isidro, the Municipal Market houses small food stalls serving regional specialties and fresh tropical fruits you won’t find elsewhere. Coffee lovers should try locally grown beans from the mountains around San Isidro, which have distinct flavor profiles from the better-known Central Valley coffees. Along the coast, fresh seafood features prominently on menus, while inland restaurants tend to focus on beef, chicken, and pork dishes.
