Twilight Peak is the highest summit of the West Needle Mountains, a subrange of the San Juan Mountains in San Juan County, Colorado. The sources record no documented discovery, naming event or 19th-century exploration tied to the peak; its recorded history is cartographic, appearing in USGS geographic-name records with a summit elevation of 13,146 feet (4,007 m).

The name Twilight Peak comes from the West Needle Mountains group it heads, and the peak is climbed by the standard route from Molas Pass to the north, past Crater Lake. The summit stands in the Weminuche Wilderness, where the San Juan National Forest boundary and wilderness rules shape how parties travel and camp.

The standard approach is a trail from Molas Pass to the north, which leads to Crater Lake; from there the summit is accessible. The peak lies in the Weminuche Wilderness of San Juan National Forest, 10.7 miles south-southwest of Silverton, so plan for high-altitude conditions and changeable mountain weather.

The mountain features three distinct summits - the main Twilight Peak, North Twilight at 13,075 feet, and South Twilight at 12,932 feet.
