- The 105,000-acre Lost Creek Wilderness is less than 40 miles southwest of Denver, with several access points. The Wilderness has a wide variety of terrain and vegetation types, from steep, rocky slopes to high mountain meadows and deep canyons. Elevations range from 8,000 feet to 12,431 feet (Bison Peak). Several pack trails exist within the wilderness including a segment of the Colorado Trail.
Recreation - No mechanized or motorized vehicles are permitted within any wilderness boundaries. Recreationists may enjoy backpacking, hiking, horseback riding, ski touring, cross-country skiing and snowshoeing.
Climate - Controlled mainly by the Rocky Mountains, weather in the Lost Creek Wilderness Area varies extremely on a yearly, daily and hourly basis. Colorado's high elevation makes the air thinner and harder to breathe. The elevation also makes it easier to get a sunburn, because there is less air between you and the sun to filter ultraviolet light. Temperatures are affected by elevation, cooling four degrees for every 1,000 feet gained.
