Hiking in Costa Rica means watching the landscape change as you move through different elevations. Each altitude brings its own climate, creating pockets where specific plants and animals have made their homes. The southern Pacific region shows this off well, with trails running from beach level up into the high mountain passes.
The microclimates here shape how you hike. Early starts help with coastal heat, while mountain trails need planning around afternoon clouds. Weather patterns change fast with elevation – you might need sunscreen and a rain jacket in the same backpack. Wildlife adapts to these changes too, with different birds and animals active at each level.
These elevation shifts mean you’ll see something different on every hike. Beach trails have their morning monkey troops and macaw flocks. Mid-elevation paths wind through dense forest where oaks and wild avocados grow. The highest trails break through the treeline into open air where winds sweep across mountain peaks. Each trail tells its own story about how Costa Rica’s mountains meet the sea.
I use these versatile trail runners on my hikes in Costa Rica. The aggressive grip tackles steep terrain while maintaining comfort for long days on mountain paths.
El Miro: Jaco’s Hidden Viewpoint Trail
The El Miro trail starts at the south end of Jaco beach, climbing steeply through forest to a dramatic clifftop viewpoint. From here, the entire curve of Jaco Bay stretches north, while the coastline south towards Playa Hermosa disappears into the distance. The morning light shows surfers catching waves below, while late afternoon brings spectacular sunsets.
Getting to the trailhead takes just minutes from central Jaco. Park near the south beach access, where a marked path leads into the trees. The climb takes 30-45 minutes, with some rope-assisted sections on the steeper parts. Early morning or late afternoon hikes avoid the midday heat.
This short but rewarding hike offers a completely different perspective on Jaco. While most visitors stick to the beach, this elevated viewpoint reveals how the mountains meet the Pacific. Macaws often fly past at eye level, and the breeze at the top provides relief from the beach heat below.
LOCATION
This hike is located at the south end of Jaco beach. You’ll cross the main highway and find the entrance across from Puddlefish.
HIKING TIME
At a brisk pace the hike will take 20 – 30 minutes. You can take some stops to spot wildlife and enjoy the art, and spend about 1 hour on the trail.
DIFFICULTY
The trail is mostly moderate with a couple washed out areas that are rutted. Not recommended for those with mobility issues. Children can complete the hike under supervision.
BEST TIME TO VISIT
Early morning before the heat or 2-3 hours before sunset for best views. Sunrise offers clearest ocean views, while sunset provides dramatic lighting across Jaco bay.
WHAT TO BRING
Water bottle, good walking shoes, camera for views. Phone for safety. Small backpack useful.
SAFETY TIPS
Hike with others when possible. Tell someone your plans. Watch footing on steep sections. Bring water even for short hike. Return before dark if hiking for sunset.
El Ascensión: Cloud Forest Peak Trail
The trail starts near the Pan-American Highway’s highest point, where clouds regularly sweep across the continental divide. This high-altitude hike offers rare access to Costa Rica’s páramo ecosystem, where stunted trees and unique vegetation adapt to life at 3,300 meters (11,000 feet).
Hidden behind a small restaurant at the mountain pass, this trail climbs through cloud forest before emerging into open páramo landscape. The stark transition from dense forest to alpine-like conditions shows how elevation shapes Costa Rica’s diverse environments.
The summit trail reveals both Caribbean and Pacific slopes on clear mornings, though clouds often roll in by mid-day. This ecosystem hosts unique highland species like the volcano junco and timberline wren, found nowhere else in Costa Rica.
LOCATION
Located at KM 89 of the Pan-American Highway (Cerro de la Muerte). There’s a wide parking area at the roadside. Trailhead starts at the road with 3,300 meters of elevation.
HIKING TIME
20 – 30 minutes to reach the summit at a steady pace. Plan for 1-2 hours total to enjoy views and return. Extra time needed for photography and bird watching.
DIFFICULTY
High altitude makes this moderate trail more challenging. Some steep/very vertical sections near top. Trail clearly marked but rocky in parts. Take time to adjust to elevation before starting.
BEST TIME TO VISIT
Early morning before clouds roll in (usually by 10 AM). Check weather as conditions change quickly. Clearest views December-April. Bring warm layers any time of year.
WHAT TO BRING
Warm jacket and layers (temps can drop below 10°C), hiking shoes with good grip, water, snacks, camera. Rain gear recommended year-round. Hat and sunscreen despite cool temps.
SAFETY TIPS
Watch for altitude symptoms. Start slow and stay hydrated. Tell someone your plans. Check weather before starting. Cell service available at trailhead. Return if weather turns bad.
Los Gigantes: Valley View Trail
High in the mountains above San Isidro del General, the Los Gigantes trail network winds through working coffee farms into pristine forest. The trails offer sweeping views across the Perez Zeledon valley, where on clear days you can see all the way to the Pacific Ocean.
These paths started as coffee farm access routes but have evolved into maintained hiking trails. As you climb, the landscape shifts from sun-drenched coffee plants to cool forest shade. The elevation gain reveals how the valley’s patchwork of farms gives way to forest-covered peaks.
Multiple viewpoints along the way showcase the region’s agricultural heritage. Morning fog often fills the valley below before burning off to reveal the expanse of San Isidro and the surrounding mountains. Local farmers still use parts of these trails, making this a unique mix of working land and natural space.
LOCATION
Located in Perez Zeledon’s mountain region. Turn off the Inter-American Highway at San Isidro, follow signs toward Cerro Chirripo. Trail network starts near the community of Quebradas.
HIKING TIME
Main loop takes 2-3 hours at steady pace. Multiple trail options ranging from 1-4 hours. Worth taking time at viewpoints and rest areas.
DIFFICULTY
Moderate with steady elevation gain. Well-maintained trails through farms and forest. Some steeper sections but regular rest spots available. Good for varied skill levels. You can drive to the top and walk across mostly level terrain to the giant trees.
BEST TIME TO VISIT
Early morning before heat and for best valley views. Clouds typically move in afternoon. Dry season (December-April) offers clearest visibility.
WHAT TO BRING
Water, sun protection, light jacket for elevation, good walking shoes, camera for views, snacks. Cash for local stores if needed.
SAFETY TIPS
Tell someone your plans. Stay on marked trails to respect farm boundaries. Watch weather as afternoon rains common. Carry enough water as sources limited.
