Twilight Peak is a 13,163-foot mountain in southwestern Colorado, the highest summit of the West Needle Mountains, a subrange of the San Juan Mountains. It rises in the Weminuche Wilderness within San Juan National Forest, about 10.7 miles south-southwest of Silverton. The mountain is most often approached from the north, with the standard route beginning at Molas Pass and following a trail toward Crater Lake before reaching the summit. Nearby North Twilight Peak and South Twilight Peak form a compact high cluster around it. Twilight Peak is best known as a remote wilderness destination and the loftiest point in this rugged part of the San Juans.
