Into the Green Lungs: Exploring Braulio Carrillo National Park from San José
Treetop trams, adrenaline ziplines, and river safaris—how to see Costa Rica’s rainforest by every angle.
The bus leaves San José before dawn and the highway tightens into a ribbon of asphalt that climbs through mist. Outside the windows, coffee plantations slide into slopes of dense, impossible green; the trees grow taller and thicker until they are a single continuous wall, dripping with epiphytes and the slow choreography of orchids. You arrive at a clearing and the forest seems to inhale. In Braulio Carrillo National Park, the rainforest is not a backdrop — it’s a living, layered world that surrounds and shifts with you: the canopy teems above like an extra sky, the midstory bristles with toucans and tanagers, and the understory hums and pulses with frogs and insects.
Trail Wisdom
Go early for wildlife
Book the first tram or an early river safari—birds and monkeys are most active in the morning and light is best for photos.
Layer for sudden rain
Carry a lightweight waterproof shell and quick-dry layers—tropical showers are frequent and unpredictable.
Secure footwear
Use grippy trail shoes—trails and platforms can be muddy or slick after rain; avoid open sandals.
Bring a local guide
Choose naturalist-led tours to translate sightings and get the best chance of spotting sloths, toucans, and monkeys.
Local Knowledge
Hidden Gems
- •Early-morning tram rides when mist threads the canopy
- •Small roadside stands along the Route 32 for fresh tropical fruit and local empanadas
Wildlife

Conservation Note
Many operators support local reserves and follow strict trail protocols; choose companies that contribute to habitat restoration and pay local guides to sustain community livelihoods.
The park was established in the late 1970s to protect central Costa Rica’s eastern rainforest corridors and watershed, and it now links several conservation areas.
Seasonal Guide
spring
Best for: birding, wildflowers, lower crowds
Challenges: intermittent rains, muddy trails
Spring transitions toward the wetter months—mornings can be calm and great for birds, but expect occasional showers that make trails slick.
summer
Best for: canopy views, aerial tram rides, family tours
Challenges: afternoon storms, higher humidity
Summer (dry season in many parts) offers more reliable skies for aerial activities; pack sun protection and stay hydrated.
fall
Best for: river safaris, monkey and sloth sightings, green-season growth
Challenges: more consistent rain, reduced road visibility
Fall brings lush vegetation and active rivers—wildlife is abundant but trails and access roads can be wet and slow.
winter
Best for: cloud-forest moods, fewer tourists, frog and amphibian activity
Challenges: heavy rain in lowlands, possible river closures
Winter is wetter and often dramatic—expect cloud-shrouded ridges and increased amphibian activity; check river levels before booking water trips.

Common Questions
How long is the aerial tram ride?
The tram experience typically covers about one mile of canopy travel and organized visits last roughly 1–1.5 hours including guided walks.
Are zipline courses safe for beginners and kids?
Most operators accept children from about 4 years old and provide harnesses, helmets, and safety briefings; confirm age and weight limits with your chosen company.

Yes—birds, monkeys, and sloths are commonly visible from the tram and canopy platforms, especially during early morning rides.
Do I need special permits to enter Braulio Carrillo National Park?
No special permit is generally required for public trails and commercial tour areas, but private reserves and research sites may have restricted access.
What’s the best time of day to visit?
Early morning is best for wildlife and softer light; afternoon often brings showers and fewer active animals.
Are river safaris safe for families?
River safaris operate with experienced guides and life jackets; river conditions can vary with rains, so operators may alter routes for safety.
What to Pack
Light rain jacket (sudden showers), grippy trail shoes (muddy trails), binoculars (wildlife viewing), insect repellent (comfort and protection)
