How to understand this park
Chirripó protects far more than Costa Rica’s highest summit. The route crosses montane forest and páramo, with shifts in temperature, radiation, wind and vegetation central to the experience.
Park admission and lodging at Base Crestones are related but separate arrangements. Lodge capacity is limited, and improvisation can remove an essential itinerary component.

Sectors, trails and routes
San Gerardo–Base Crestones
Main ascent · long dayThe route gains substantial elevation and rewards conservative pacing from the first kilometres. Pack weight and departure time matter as much as distance.
High-mountain internal network
Trails from 3.1 to 25 km according to SINACValle de los Conejos, lakes and summits require realistic objectives from the base rather than attempting everything.
Authorized alternative routes
San Jerónimo/Sabana Leones and Herradura–UránThese are not spontaneous shortcuts: each has separate management, difficulty and logistics.
What to combine nearby

Base for sleep, meals, packing and community projects before or after the ascent.
El General valley
A recovery night at lower elevation helps avoid driving exhausted immediately after descending.
