Gap and Shelf Lakes Trail

Hikers can expect a varied and often rocky terrain, including sections that require boulder hopping, particularly along the shorelines of the lakes. The route involves steep grades, especially when ascending to the Shelf Lakes, which sit at around 11,000 feet in elevation. At times, the trail may become less distinct or disappear in rocky areas, necessitating some minor scrambling. You will traverse through tundra and may encounter wet sections, particularly after the Shelf Lakes.

The trail winds past numerous crystalline alpine lakes, including South Gap Lake and North Gap Lake, which are among the largest in the area. The Shelf Lakes themselves are a series of narrow bodies of water nestled against the northern edge of Browns Peak. Dominating the landscape are surrounding peaks such as the imposing Medicine Bow Peak (12,013 feet) and Browns Peak (11,722 feet), offering dramatic granite backdrops. You'll also get expansive views of the vast lake district and excellent perspectives of Sugarloaf Mountain.

Due to heavy snow, the road to the trailhead is typically inaccessible from mid-fall to early-to-mid-July. Therefore, late summer and early fall are the primary hiking seasons. During the summer, the area bursts with vibrant wildflowers, and the fall brings awesome tonality to the landscape.

The trailhead at Lewis Lake is a popular starting point. Parking here may require a day-use fee. It's always a good idea to check current regulations and fees for the Medicine Bow-Routt National Forest before your visit.

While the provided information does not explicitly state dog-friendliness, trails within the Medicine Bow-Routt National Forest generally allow dogs, often requiring them to be on a leash. It's best to confirm specific regulations with the forest service before bringing your dog.

Given the unpredictable mountain weather, including sudden electrical storms, hikers should be prepared. Carry adequate water, wear appropriate footwear for rocky and potentially wet terrain, and bring layers of clothing. Navigation tools are also recommended as sections of the trail can be less distinct.

While specific wildlife sightings are not guaranteed, alpine environments like this can be home to various species. Keep an eye out for marmots, pikas, and various bird species. Larger mammals like deer or elk might also be present, especially during quieter times.

When hiking in the Medicine Bow-Routt National Forest, always practice Leave No Trace principles. This includes packing out all trash, staying on marked trails, and respecting wildlife. Campfire restrictions may be in place, especially during dry periods. Check the official forest service website for the most current regulations regarding permits, camping, and other activities.

Beyond the varied and rocky terrain, hikers should be prepared for steep grades and sections where the trail may be less distinct, requiring some minor scrambling. The high elevation (topping 11,000 feet) means thinner air, and mountain weather can change rapidly, including sudden electrical storms. Always carry sufficient water and be ready for changing conditions.
