Pico de Orizaba, also known as Citlaltépetl, is the highest mountain in Mexico and a popular destination for experienced mountaineers. Climbing requires technical skills and acclimatization due to the high altitude. Accessibility to the base is possible via 4x4 vehicles, but the ascent involves glacier travel. Solo climbs are discouraged due to the inherent risks; guided tours are highly recommended and widely available from outfitters in nearby towns like Tlachichuca. The best time to climb is during the dry season from November to March. The cost of a guided climb typically ranges from $500 to $1500 USD, depending on the duration and services included. A typical ascent and descent takes 2-3 days. Note that summiting is physically demanding and should only be attempted by individuals in excellent physical condition.
