Where to stay
The most popular refuge is Whymper, situated at 16, 400 feet and well-equipped with comfortable bunk-beds, bathrooms, basic food supplies and a fireplace.
Refuge Carrell, at 15, 750 feet, is also well prepared to host climbers. Because of its location, to start the ascent from there you will need to leave a bit earlier.
There are two campsites closer to Chimborazo: El Castillo and Moraine. The former can get pummeled by snow fall in the case of strong wind or avalanche.
