Mount Walter, Mountain summit in Taos Mountains, New Mexico, US.

Mount Walter is a summit in the Sangre de Cristo mountain range, part of the larger Rocky Mountains system. The peak stands above 4,000 meters and sits within the Carson National Forest in northern New Mexico.

The surrounding area became a protected wilderness in 1964 when Congress designated the Wheeler Peak Wilderness. This protection preserved the landscape and restricted development in the high mountain region.

Mount Walter takes its name from a nearby feature in the Taos Mountains, and it is climbed mainly as a short detour from Wheeler Peak, 0.4 miles (0.6 km) to the south-southwest. Hikers reach it on the Williams Lake trail route out of Taos Ski Valley, and the summit lies inside the Wheeler Peak Wilderness of Carson National Forest.

Hikers can access the mountain from trailheads near Taos, with the main routes departing from the Taos Ski Valley area. The terrain is steep and conditions change with altitude, so preparation is essential for any ascent.

The peak rises just slightly above a nearby unnamed point, yet holds the distinction of being New Mexico's second-highest named summit. This small difference in elevation is enough to give the mountain its independent status among the state's highest peaks.
