Servimont is a climber-owned outfit passed down through the Reyes family since the 1930s. As the longest-running operation in the area, it also acts as a Red Cross rescue facility. It’s based in the small town of Tlachichuca (2600m), which is a common starting point for expeditions. It is the only Mexican operator to offer Pico de Orizaba ascents.

Shorter and less demanding ascents on offer are those of Iztaccihuatl, Malinche and Nevado de Toluca volcanoes. Book your expedition with Servimont two to four months in advance and allow four to seven days to acclimatize, summit and return.
