The tour starts and ends in Quito airport, where we meet on day one at around lunchtime. If you start with this trip in Ecuador, it is recommended to plan a night in Quito city at the beginning.
For the basis program (observation of the volcano from near the accommodation and short excursions nearby), there is no particular physical effort.
For those intending to camp near the volcano, this requires a 5-6 hours partially strenuous hike through rainforest on partially very steep, uneven, slippery, often muddy terrain. Temperatures can drop to 5-10 deg at night. Combined with high humidity, this means it can be very chilly.
