Tips for Visiting Cerro Chirripó
- Reserve accommodation in San Gerardo de Rivas or in Chirripó National Park's ranger station well in advance during the high season (Dec-Apr).
- Start pre-dawn from the second ranger checkpoint to reach the summit around sunrise; bring warm layers - summit temperatures can fall below freezing.
- Acclimatize: the trail gains a lot of elevation rapidly; hikers who attempt the summit in one day should be fit and prepared.
