Pike-San Isabel NF — Salida RD

Sunnyside Lakes is an 11.2-mile out-and-back trail located in Colorado that offers hikers a moderate alpine experience. The route features 872 feet of elevation gain spread across the round-trip distance, making it accessible for intermediate hikers seeking a full day in the backcountry. The trail leads to a series of alpine lakes, providing scenic water features and potential wildlife viewing opportunities. The out-and-back format allows hikers to turn back at any point based on fitness level or time constraints, with the midpoint turnaround at the lakes themselves. This hike is managed by the local land management agency and traverses designated wilderness terrain. The trail's moderate elevation gain and distance combination makes it suitable for those with solid hiking experience but not requiring mountaineering skills. Hikers should plan for a full day outing and come prepared with adequate water and supplies. The alpine setting means weather can change quickly, so bring appropriate layered clothing. The best hiking season typically spans from late spring through early fall, depending on snowmelt and weather conditions in the Colorado high country.
