Buchanan Pass Loop

The Buchanan Pass Loop is a challenging route. While the Komoot data suggests a duration of around 1 hour and 45 minutes for jogging, this is likely an underestimate for most. Given its 15.5 km distance, significant elevation gain, and difficult terrain, experienced trail runners often take several hours to complete it. It's a demanding long-distance run, so plan accordingly.

No, this loop is largely considered a difficult trail and is not recommended for beginners. It involves substantial elevation gain and loss, sustained climbs to passes over 11,000 feet, and very technical terrain with loose rocks, roots, and downed trees. Acclimatization to high altitude is also important.

While there isn't a specific entrance fee for the Arapaho-Roosevelt National Forest itself, you will need to be aware of permits. An Indian Peaks Wilderness Permit is required for overnight stays. During summer months (June-October), timed entry parking permits are often required for the Brainard Lake Recreation Area, which is a common access point for trails in the Indian Peaks Wilderness. Always check current regulations before you go.

Access to the Buchanan Pass Loop typically involves trailheads within the Brainard Lake Recreation Area. Parking availability can be limited, especially during peak season. During summer months, timed entry parking permits may be required for this area. Consider arriving early to secure a spot, or research shuttle options if available.

The Indian Peaks Wilderness, where this loop is located, generally allows dogs but requires them to be on a leash at all times. Always check the most current regulations for the specific area you plan to visit, as rules can change.

The best time to jog this loop is typically from late June through September. During this period, the snow has usually melted from the high passes, and wildflowers are abundant. However, be prepared for afternoon thunderstorms, especially at higher elevations, and always check weather conditions before heading out.

The terrain is rugged and varied. Expect a mix of loose and rocky trail, roots, rocks, and downed trees. While some sections are runnable even uphill, others are very technical and challenging, particularly the steep climbs and descents from Buchanan Pass and Pawnee Pass. Much of the loop traverses above treeline, exposing you to the elements.

This loop is renowned for its stunning scenery. You'll be treated to wildflower-speckled meadows, cascading waterfalls like Timberline Falls, running creeks, and endless groves of subalpine forest. Highlights include views of Mount Audubon, the Continental Divide, and various jagged peaks. You'll also pass by Beaver Reservoir and other alpine lakes like Lake Isabelle, Mirror Lake, and Crater Lake.

While the loop can be completed in either direction, some experienced runners recommend doing Buchanan Pass first (counter-clockwise). This approach helps avoid a particularly technical and steep descent from Pawnee Pass, which can be challenging to navigate downhill.

Yes, the route utilizes sections of several official trails. You'll find yourself on parts of the Buchannan Pass Trail, Sourdough Trail, Coney Creek Road, County Road 92J, Beaver Reservoir Cutoff Trail, Coney Flats Road, Beaver Creek Trail, and Coney Creek Spur.

Given the length, elevation, and variable conditions, pack essentials like plenty of water and snacks, a map and compass/GPS, extra layers for changing weather (even in summer), rain gear, sun protection (hat, sunscreen), and a first-aid kit. Sturdy trail running shoes with good ankle support are crucial for the rocky terrain.
