Mosca Pass Trail Professional Reviews and Guides
"This is an easy climb to a high pass on the crest of the range, with views of the San Luis and Wet Mountain Valleys. Camping areas are are available throughout much of the valley. A backcountry permit is required. From the Mosca Pass Trailhead on the west side of the range, Trail 883 starts at the Montville self-guided trail. Follow it to the upper bridge crossing and then go east along the trail on the north side of the creek.
Climb up the narrow and steep-walled Mosca Creek valley for about 2.0 miles. For the last mile to the top of the pass, the valley becomes broader with some open meadows, and the grade of the trail becomes flatter. Views of the dunes and the San Luis Valley to the west become more and more impressive as you approach the pass."
--Jason Moore, Revised by Lee Hart, Hiking Colorado's Sangre de Cristos and Great Sand Dunes (Falcon Guides).
"Constituting the "preserve" portion of the Great Sand Dunes National Park and Preserve are a string of summits within the Sangre de Cristo Mountains that tower over the dunes to the east. The 3.5-mile Mosca Pass Trail offers a nice introduction to the forested portions of these peaks. The Mosca Pass Trail begins by following the Montville Nature Trail east.This 0.5-mile guided loop trail explores the former town site of Montville. Once complete with an orchard, a store, some twenty houses, and a post office, Montville was established in the 1880's."
