Nevado de Colima, Mountain in Jalisco, Mexico.

Nevado de Colima is an ancient volcanic massif in Jalisco, western Mexico, reaching 4,260 m above sea level and showing no volcanic activity. Its summit is a sharp, bare dark grey rock peak with a snow-covered area on its left side; below it the mountain slopes outward into steep, irregular ridges. The upper slopes are largely snow-covered, broken by patches of dark rock, and lower down the snow becomes patchier over dark brown and green vegetation.

The summit is heavily eroded, which has made parts of its violent eruptive history hard to reconstruct. Pyroclastic flows and lava remains from a catastrophic eruption, probably not older than the Pleistocene, lie up to 80 km from the crater. On 5 September 1936 President Lázaro Cárdenas created the Nevado de Colima National Park over 6,554 hectares, also protecting the neighbouring Volcán de Fuego.

The name distinguishes the Nevado from the active Volcán de Fuego beside it; the national park's main draw is the contrast between the two summits, the Picacho and the Volcán de Fuego. The park was decreed by President Lázaro Cárdenas del Río on 5 September 1936, covering 6,554 hectares, and protects both peaks.

The access road is steep and requires four-wheel-drive vehicles to navigate safely. Visitors should arrive in good physical condition and be prepared for conditions that change with higher elevation.
