Cerro Chirripó

Chirripó reaches three thousand eight hundred and twenty-one metres, the highest point in Costa Rica, and the climb is a genuine mountain trip rather than a walk: about fourteen kilometres and two thousand metres of ascent from San Gerardo de Rivas to the Crestones base hostel, then a further five kilometres to the summit, usually walked in the dark to arrive for sunrise. On a clear morning both the Pacific and the Caribbean are visible from the top. The upper slopes are páramo, a high-altitude shrubland found nowhere else in Central America outside these mountains, shaped by fires and studded with glacial lakes and the rock towers called Los Crestones.

What you actually see

• The summit at dawn - both oceans visible on a clear morning.
• Los Crestones - the rock towers above the base hostel.
• The páramo - high shrubland unique to the Talamanca range.
• The glacial lakes - remnants of the last ice age in the cirques.

When to go

December to April is the dry season and the only sensible window; the trail closes for maintenance in parts of the wet season. Permits and hostel beds are allocated through an online system and released in advance; they sell out quickly for weekends and holidays.

Honest expectations

You cannot climb it without a permit and a booked bed at the base hostel, and both are limited and go early. The ascent is long and steep, and altitude affects people who arrive from sea level the day before. The hostel is basic, unheated and cold, with temperatures near freezing at night. Porters can be hired and most people should.
