The Lost Lake and East Fork Loop is primarily accessed from trailheads in the Red River area, within the Carson National Forest. Specific parking details can vary, so it's always best to check local forest service information or komoot's tour details for the most current trailhead access points before you go.
No, the Lost Lake and East Fork Loop is considered a difficult hike. It involves significant elevation gain (over 1,180 meters or 3,870 feet), challenging terrain with roots, rocks, exposed ridges, and steep sections. Hikers should have good to very good fitness and experience with high alpine conditions.
The best time to hike the Lost Lake and East Fork Loop is during the summer and early fall. Due to its high alpine elevation, the trail can be snow-packed from mid-October to mid-June, making it impassable or very challenging during those months.
Generally, there are no specific permits required for day hiking on the Lost Lake and East Fork Loop within the Carson National Forest. However, standard forest regulations apply, and some areas might require a recreation pass for parking. Always check the official Carson National Forest website for the latest information on fees or regulations before your visit.
Yes, dogs are generally allowed on trails within the Carson National Forest, including the Lost Lake and East Fork Loop. However, they must be kept on a leash to protect wildlife and ensure a pleasant experience for all trail users. Please remember to pack out all pet waste.
The terrain on this loop is diverse and challenging. You'll encounter long climbs through lush forests with roots and rocks, exposed ridges, talus slopes, and steep avalanche terrain. Higher sections feature open rock fields and potential exposure to cliffs. Switchbacks are common, and there are several creek crossings. The environment transitions from spruce and fir forests to open meadows as you gain elevation.
The loop offers epic high alpine scenery with panoramic views of the Sangre de Cristo Mountains. Key highlights include the extremely beautiful Lost Lake and Horseshoe Lake. You'll also get glimpses of Wheeler Peak's eastern slopes, pass through spruce and fir forests, open meadows, and areas with cascading waterfalls, especially vibrant with wildflowers in season.
Yes, the route incorporates sections of several other trails. You will spend a significant portion on the Lost Lake Trail #91, and also pass through parts of the Middle Fork (487), Wheeler Peak Trail #90, and East Fork Trail #56.
Be prepared for significant elevation changes and high-altitude conditions, as the trail reaches a maximum elevation of 11,549 feet. The upper elevations can be snow-packed well into June, so check conditions before you go. Sections with talus slopes and open rock fields require careful footing. Carrying sufficient water, layers of clothing, and navigation tools is crucial for this challenging wilderness experience.
The diverse habitats along the loop support various wildlife. You might spot cavity-nesting birds, pine martens, and native bats. Keep an eye out for larger mammals as well, though they are often more elusive. Remember to observe wildlife from a distance and never feed animals.
Given the trail's difficulty and high alpine environment, pack essentials like plenty of water, high-energy snacks, sun protection (hat, sunscreen), and layers of clothing to adapt to changing weather. Sturdy hiking boots are a must for the varied terrain. A map, compass or GPS device, and a first-aid kit are also highly recommended for safety.
