Chimborazo is Ecuador’s highest mountain at 6,263 m, and the point on Earth’s surface farthest from its centre. It gives hikers and climbers two different days. Anyone acclimatized can drive to the Hermanos Carrel refuge (4,850 m) and walk 900 m up to the Whymper refuge and the Cóndor Cocha lagoon; the climb to the top is a serious night glacier ascent with a certified mountain guide. Entry to the Chimborazo reserve is free.

How high is Chimborazo?
A GPS survey on 5 February 2016 by Ecuador’s military geographic institute (IGM), France’s IRD and IG-EPN measured the top at 6,263.47 m, replacing the older 6,268 m. Because the Earth bulges at the equator, that same survey put the top 6,384,415.98 m from the planet’s centre, about 2 km farther out than the top of Everest. That is the fact behind the line that Chimborazo is the closest point to the sun.
The refuge hike
The road inside the Reserva de Producción de Fauna Chimborazo ends at the Hermanos Carrel refuge, which reopened in April 2022 and is the only refuge in Ecuador reachable by vehicle at that height. From there a 900 m path climbs to the Whymper refuge, and a little higher to Cóndor Cocha, a small lagoon at about 5,100 m. The walk is short, but you are going from 4,850 m to over 5,000 m: walk slowly, and turn back if you get a headache or feel dizzy.
Two things to know before you go. In June 2025 local guides reported the Carrel refuge without water, electricity or heating, so bring your own water and do not count on a hot drink. And in August 2025 the press reported people at the access points demanding US$45 for “guiding”: entry is free and that charge is illegal.
Climbing to the top
The main route is El Castillo, on the west ridge. Climbers sleep at or near the refuges, leave before midnight and aim to reach the top around sunrise, before the sun softens the snow; the descent takes the rest of the morning. It is longer and higher than Cotopaxi, and most people climb Cotopaxi or another 5,000 m glacier peak first. A June 2026 guide in El Espectador describes a certified high-mountain guide as mandatory for the top, and Ecuador’s 2020 adventure-tourism regulation (Acuerdo Ministerial 2020-005) requires commercial climbs to use a guide specialised in mountaineering.
- Acclimatize first: several days around Quito and Riobamba with hikes above 4,000 m, ideally including Cotopaxi or a refuge night.
- Approach day: drive to the Carrel refuge, walk up to the Whymper refuge, rest.
- Night climb: leave before midnight roped to your guide, on crampons over snow and ice.
- Top and descent: top around sunrise, then down to the refuge before the snow softens.
Altitude and best time
Our rule in Cusco is at least two nights at altitude before the first hard day of the Classic Inca Trail, whose high point is 4,215 m. Chimborazo’s refuges start 635 m higher than that pass, and the top is more than 2,000 m higher, so the refuge hike needs a few days at altitude first and the climb needs a week or more. Our altitude sickness guide lists the signs that mean go down now.
For the climb, El Espectador’s 2026 guide gives November to February and May to July as the best months. The refuge hike is possible in most weather, but cloud often closes in by midday, so arrive early.
