Mountaineering on Pico de Orizaba

Pico de Orizaba — known in Nahuatl as Citlaltépetl, 'mountain of the star' — is the third-highest volcano in North America and the highest peak in Mexico, standing at 5,636 metres above sea level. Its dormant crater crowns a perfectly symmetrical cone draped in permanent glaciers which, though retreating due to climate change, still create demanding and technical high-altitude climbing conditions.

The standard ascent follows the northern route via the Jamapa Glacier: from the Piedra Grande refuge at 4,260 m, climbers make their way up mixed rock-and-ice terrain to reach the crater rim. Maximum gradients exceed 45 degrees in some sections, making 12-point crampons and an ice axe indispensable above 5,000 m. The final goal is the summit, known simply as 'el Pico', at 5,636 m.

The view from the top on a clear day is extraordinary: to the north, Cofre de Perote; to the south, Popocatépetl and Iztaccíhuatl; and on the clearest days, the Gulf of Mexico some 200 km away. Those who reach the top describe the sensation as standing literally above the clouds.

History

Pico de Orizaba's first documented ascent was completed in 1848 by American topographer William Fraser Tolmie and naturalist Gustavo Brinckerhoff, though the indigenous peoples of the region had known and revered it long before. The Aztecs called it Citlaltépetl and considered it the abode of the rain god. During the colonial era, Franciscan friars climbed its flanks in the 16th century in search of sulfur to make gunpowder. Today it is one of Mexico's '7 Summits' and attracts more than 2,000 mountaineers per year, making it one of the most climbed volcanoes in the Americas.

What you need

• 12-point crampons (steel, not aluminium)
• 60-70 cm ice axe
• Waterproof gaiters
• Mountaineering boots, plastic or leather (minimum B2/B3 rating)
• Technical layered clothing: thermal base layer, fleece mid-layer, Gore-Tex shell
• UV4-filter sunglasses or glacier goggles (snow at 5,000 m reflects 80% of UV radiation)
• Climbing helmet (loose rock on the approach)
• Harness + rope for roping up on the glacier (optional but recommended)
• Headlamps with lithium batteries (not alkaline — they fail in the cold)
• High-altitude first-aid kit with altitude sickness medication (Diamox — consult a doctor first)
• Certified mountain guide: strongly recommended for first-timers

How to get there

The most commonly used access point is from the Veracruz side. From the city of Orizaba (reachable by ADO bus from Mexico City or Veracruz in 3-4 hours), take a shared van or taxi to Tlachichuca (45 min). Tlachichuca is the base village where local guides are hired and 4x4 truck transfers to the Piedra Grande refuge (4,260 m) are organised — the only vehicle capable of navigating the dirt track. The 4x4 journey from Tlachichuca takes 2-3 hours depending on conditions. From Puebla, the route is similar: take Highway 150D towards Orizaba, then continue to Tlachichuca.

The Piedra Grande refuge has capacity for 30-40 people, a basic kitchen, and running water. It is highly recommended to arrive the day before and acclimatise for at least 12 hours before your summit attempt.
