Why climb it
Four reasons to climb Cayambe
01
A volcano split by the equator
Its summit is in the Northern Hemisphere and its base in the Southern: it is the only volcano in the world on the equator.
02
Ecuador's third-highest peak
At 5790 m, only Chimborazo and Cotopaxi are higher. It lies inside the Cayambe Coca Ecological Reserve.
03
A long climb: come in good shape
About 1200 m of elevation gain from the refuge, in roughly 6 hours: a goal for those who already have a good fitness base.
04
A night at the refuge and a midnight start
You sleep at the Ruales-Oleas-Berge refuge, at 4600 m, and set out around midnight to reach the summit in the morning.
Who is it for? For those with good physical preparation and good hydration. Before departure, your professional guide gives a technical briefing.

What makes it special
A mountain split by the equator
On the equator
Its summit lies about 3 km north of the Equator line, and the line crosses its southern slope, at about 4690 m.
A great ice cap
Its ice cover spans about 22 km² and it is the only point on the Equator line with snow.
A volcano with a history
Its last eruption was between 1785 and 1786. Today it is monitored by the Geophysical Institute of the Escuela Politécnica Nacional.
Inside a reserve
It lies in the Cayambe Coca Ecological Reserve, a large protected area in the north of the country.
Its name
Why is it called Cayambe?
It is a name of ancestral origin and its meaning is debated. One explanation joins two words, cay, “young”, and bi, “water” or “source of life”.
Other proposals link it with “ice” (kayan, in Caranqui) or with “high, cold place” (cajan, in Quechua). Scholars have not reached a consensus.

young
Bi
water, source of life
First to climb it
Who climbed it first
1880
Edward Whymper, Jean-Antoine and Louis Carrel
The British mountaineer and his Italian guides make the first ascent in April 1880. They leave a camp at about 4500 m at 4:40 am and reach the summit shortly after 10 am. Whymper had already made the first ascent of the Matterhorn.

How the climb works
What summit night is like
1
Machachi → refuge
We leave Machachi for the Cayambe Coca Ecological Reserve checkpoint and continue to the Ruales-Oleas-Berge refuge, at 4600 m.
2
Dinner and rest
We settle into the refuge, have dinner (included) and rest a few hours.
3
Around midnight, the summit
We start the climb: about 1200 m of elevation gain from the refuge, in roughly 6 hours, roped up and with crampons and ice axe.
4
Descent to the refuge
Back at the refuge we have the included breakfast.
5
Return to Machachi
We descend and go back to Machachi, our starting point.

Why at midnight?
We set out at night because the snow is firmer and the crevasses are safer. That way we come back down before the sun softens the glacier.
