Cerro Chirripó

Site grade
EpicFeatured2,050 m of gain in 17 km to Crestones on a trail SINAC grades extreme, then 5.1 km more to 3,820 m. The 2026 race was run in mud, rain and cold with falls reported; a 3:22 winning time says how steep it is.
The experience
From 1,350 m at the San Gerardo plaza the trail climbs 2,050 m in 14.5 km to the Crestones lodge, then 5.1 km more to the 3,820 m summit, through cloud forest, páramo and glacial valleys, and comes back the same way.
The Carrera Internacional al Cerro Chirripó has run the 34 km to Crestones and back every year since 1989, capped at 225 runners to protect the park. In 2026 the men's winner needed 3:22:14 and the women's, a Cabécar athlete, took her third title.
Chirripó is a Cabécar word SINAC translates as land of eternal waters; the park was created on 19 August 1975 and now covers 50,150 hectares. The Crestones rock spires are a national symbol. Father Agustín Blessing, a Talamanca missionary, is recorded by SINAC as the first outsider on the summit, in 1904. The race is organized by the Asociación de Desarrollo Integral de San Gerardo de Rivas; its 39th edition is set for 27 February 2027.
Where the sources disagreeEntry is by SINAC permit only, reserved through the online system, with in-person registration at the park office in San Gerardo the day before, 8:00 to 12:00 and 13:00 to 16:00, and entry only between 03:00 and 10:00. The Crestones lodge holds 60 people a night and the permits sell out months ahead in the dry season. SINAC's rules bar sporting activities that disturb the park, drones, pets, alcohol, fires and single-use plastics; the race is the one authorized sporting event. Third-party sources report that the park closes to other visitors on race weekend and for maintenance in late May; SINAC's page states neither, so check. The 34 km headline is the race course to Crestones and back; the summit adds 5.1 km each way, so the full summit run is beyond 44 km by SINAC's own legs. The 2026 race was run in mud and rain with falls.

Route sections
The park admits walkers only between 03:00 and 10:00, registered the day before at the office in the village. Runners leave in the dark up the road and the first forest switchbacks.02 · The Cloud Forest LadderPark boundary to Llano Bonito
Oak forest thick with epiphytes, mud on the steps in the green season, the Llano Bonito refuge as the first place to fill a bottle.03 · Monte Sin FeLlano Bonito to Base Crestones
The climb leaves the trees for páramo; the mountain of no faith earns its name in the last third to the lodge at 3,393 m, where the race turns and the beds are.04 · The Last 5.1Base Crestones to the summit
Glacial valleys, the Lago San Juan, and a rock scramble to the sign at 3,820 m. On a clear dawn both oceans show; the wind and frost are the price.05 · The Long Way DownSummit to San Gerardo
Nearly twenty kilometres of descent through everything you climbed. Porters take the bags; nobody takes the quads.

SINAC's entry hours for Chirripó are 03:00 to 10:00, every day, with registration done the day before at the office in San Gerardo. The early gate exists because the climb to Crestones is a full day; runners use it to be on the summit by nine.
