Quick Answers
Cerro Chirripó, At a Glance
How tall is Cerro Chirripó?
3,820 meters (12,536 ft) — the highest peak in Costa Rica, inside Chirripó National Park.
How long is the hike?
14.5 km from the San Gerardo trailhead to Crestones Base Camp, then another 5.5 km each way to the summit.
Do I need a permit?
Yes. Booked through SINAC’s website, with permits released up to six months in advance.
Where do I sleep?
Crestones Base Camp, a basic mountain lodge at roughly 3,400 meters, booked separately from your park permit.
Do I need a guide?
Not on the San Gerardo route, the most popular entry point. Other access points do require one.
Best time to hike?
Dry season, roughly December through April. The park closes the last two weeks of May for trail maintenance.
Not a Casual Afternoon Hike
Reaching Cerro Chirripó’s summit means walking roughly 40 kilometers round trip over two to three days, most of it uphill on exposed terrain. It is the highest point in Costa Rica and one of the more demanding hikes in Central America — not a side activity to pair with a beach week. Anyone planning the climb should budget real preparation time, not just a free morning.
Permits and Reservations
Every hiker needs a park permit from SINAC, Costa Rica’s national conservation system, purchased online before arrival. Permits open up to six months in advance, and weekend dates — especially around Easter week — sell out early. A separate reservation covers your bed and meals at Crestones Base Camp, arranged with the lodge’s operator once your SINAC permit is confirmed.
Same-day permits are not available. Every hiker must also check in at the San Gerardo park office by 4 p.m. the day before starting the trail.
What the Two Days Look Like
Day one covers the 14.5 kilometers from the trailhead near San Gerardo de Rivas up to Crestones Base Camp, gaining roughly 2,200 meters of elevation on a well-marked trail. Most hikers start before sunrise to beat the afternoon cloud cover. Day two is a lighter push: 5.5 kilometers each way to the summit and back, often timed for sunrise before returning to base camp or descending the full way to San Gerardo the same day.
Altitude and Fitness
Crestones Base Camp sits at about 3,400 meters, and temperatures there drop close to freezing overnight — a different climate than the rest of Costa Rica. The altitude gain is enough to cause mild symptoms in some hikers, so a slow, steady pace on day one and a full night of rest before summiting help more than raw fitness alone. Reasonable cardiovascular conditioning is still expected; this is not a first hike.
What to Pack
- Layered clothing, including something warm for the cold nights at base camp
- A headlamp for a pre-dawn summit push
- A refillable water bottle or hydration bladder
- Trekking poles for the steep sections
- Basic rain protection — weather changes quickly at altitude
