"If you want to get out of the city for the day, the Volcano Hiking Tour is a full 11–12 hour day trip with pick-up at your accommodation; you'll walk trails with an experienced mountaineering guide, learn about the flora and fauna, and see the legendary Paso de Cortés — the spot where Hernán Cortés and his army passed through on their way to the Aztec city of Tenochtitlan in 1519. It requires a fair level of fitness since you'll be hiking at altitude on uneven terrain. Tours start at 1,100 MXN." - Matthew Kepnes
