The loop typically starts and ends at the Trappers Lake Trailhead. There is parking available there, but it can fill up, especially during peak season.
The terrain is quite varied and demanding. You'll jog through meadows, dense pine forests, and aspen stands, crossing streams and passing beaver ponds. A significant portion traverses areas affected by the 2002 Big Fish wildfire, offering unique views among 'standing ghost trees'. As you ascend, expect tundra and rocky sections, especially around Wall Lake, which involves a steady, steep climb.
No, this route is rated as 'difficult' for jogging. With its 14-mile length, significant elevation gain of over 2,200 feet, and high altitude (minimum 9,598 feet), it requires very good fitness and sure-footedness. It's best suited for experienced joggers.
The loop is renowned for its breathtaking natural beauty. You'll be treated to views of pristine alpine lakes, including Trappers Lake and Wall Lake with its dramatic backdrop. The higher elevations offer panoramic views of the surrounding mountains and the characteristic flat-topped mesas of the Flat Tops Wilderness. The 'ghost trees' from the wildfire also create a unique, ethereal landscape.
The best time to jog this loop is typically from late spring to early fall, generally June through September, when the snow has melted and the weather is most favorable. Always check current trail conditions before you go, as high-altitude sections can retain snow later into the season.
Generally, there are no permits or entrance fees required for day use in the Flat Tops Wilderness Area. However, specific regulations apply to wilderness areas, such as Leave No Trace principles, group size limits, and restrictions on motorized vehicles and bicycles. Always check with the local Forest Service office for the most current regulations before your visit.
Yes, dogs are generally allowed on this trail within the Flat Tops Wilderness. However, they must be kept on a leash at all times to protect wildlife and ensure a pleasant experience for all users. Please remember to pack out all pet waste.
Yes, the route incorporates sections of several official trails. You'll spend a significant portion on the Wall Lake Trail and the Trappers Lake Trail. Other paths you'll encounter include the Carhart Trail, Outlet Horse Trail, Outlet Trail, Island Lakes Trail, Little Trappers Trail, Scotts Bay Overlook Trail, Scotts Lake Trail, and Oyster Lake Trail.
The Flat Tops Wilderness is home to abundant wildlife. You have a good chance of spotting elk, especially in the meadows and forested areas. Keep an eye out for other mammals and various bird species. The area is also known for its native cutthroat trout in Trappers Lake.
Given the trail's difficulty, length, and high altitude, you should pack sturdy trail running shoes, layers of clothing for changing weather, plenty of water (as sources may be limited or require filtration), high-energy snacks, sun protection, a map and compass or GPS device, and bear spray. Be prepared for sudden weather changes, even in summer.
Yes, if the full Trappers Lake and Wall Lake Loop is too challenging, a shorter 6-mile Trappers Lake Loop is available. While still considered intermediate with a 607 ft climb, it offers a less strenuous option to experience the beauty of the area around Trappers Lake.
