Climbing high-altitude mountains and volcanoes are demanding
excursions which are suitable for people who are in good physical
condition. These are not permitted for people who have trouble
with heights or have a heart condition.
The preferable season for climbing is September to April, bearing
in mind complications that may arise from the altiplanic rainy
season (January and February). The coldest season at high altitude
is from May to August.
For explorations higher than 4,000 mts guests have to be over
12 years old. For hikes higher than 5,000 mts guests have to
be over 18.
