Upper and Old Bristlecone Trail Loop

The Upper and Old Bristlecone Trail, including the full loop, is currently closed due to significant damage from Tropical Storm Hilary in August 2023. The U.S. Forest Service expects these sections to remain closed until 2029 for repairs and safety concerns. A portion of the Lower Bristlecone Trail might be available as an out-and-back hike, but the full loop is inaccessible.

Before the closure, hikers typically parked at either the Upper or Lower Bristlecone Trailheads in Lee Canyon. Given the current closure of the Upper and Old Bristlecone Trails, parking options are limited. If a portion of the Lower Bristlecone Trail is open, parking would be available at its trailhead. Always check local Forest Service updates for current access and parking information.

Generally, trails in the Spring Mountains National Recreation Area, including the Bristlecone area, are dog-friendly. However, dogs must be kept on a leash at all times. Given the current closure of the Upper and Old Bristlecone Trails, please ensure any alternative trails you choose are also dog-friendly and adhere to all regulations.

When the trails are open, the Bristlecone area is particularly popular during the warmer months (late spring through fall) due to its significantly cooler temperatures compared to downtown Las Vegas. Fall offers vibrant quaking aspen colors. However, with the current closure, this question is more relevant for when the trails reopen, expected in 2029.

Generally, there are no entrance fees or permits required for day hiking on most trails within the Spring Mountains National Recreation Area, including the Bristlecone area. However, specific activities or areas might require permits, so it's always best to check the official USDA Forest Service website for the most current regulations before your visit.

Before its closure, the loop offered varied terrain. Starting from the Upper Trailhead, it typically wound through forests of fir and quaking aspen. As it climbed, vegetation became sparser, leading to rugged stands of ancient bristlecone pines. The path included wide footpaths, singletrack sections, and parts that followed an old service road, with some rocky spots at higher elevations.

When open, the trail is renowned for its ancient Bristlecone Pines, some of the longest-lived trees on Earth. Hikers can also enjoy vibrant aspen groves, especially beautiful in the fall, and panoramic views of the surrounding mountain peaks, the Lee Canyon ski area, and the canyon itself. Specific highlights include the Upper Bristlecone Trail (Fenced Beginning Section), Aspen Grove, Saddle and Overlook, and Mummy Mountain Viewpoint.

The diverse ecosystems of the Spring Mountains National Recreation Area offer opportunities to spot various wildlife. Hikers might encounter the unique Mount Charleston Chipmunk, various bird species, and occasionally wild horses. Always observe wildlife from a distance and do not feed them.

Yes, when fully open, the route passes through sections of the Upper Bristlecone Trail, Old Bristlecone, and Bonanza Trail. Other nearby trails in the system include the Lower Bristlecone Trail, West Bristlecone, SKOTA, Peanut Butter & Flow, and Green Trail.

Before its closure, the loop was generally considered moderate to moderately strenuous. The elevation gain of approximately 389 meters (1,277 feet) over its 8.5 km (5.3 miles) length required a decent level of fitness. Hikers were advised to acclimate to the higher altitude if coming from lower elevations.

Lee Canyon offers limited amenities. The Lee Canyon Ski Resort (now Lee Canyon) provides some facilities, especially during ski season, which may include food and restrooms. For more extensive dining and accommodation options, you would need to travel further down the mountain towards Las Vegas. Always plan to bring sufficient water and snacks for your hike.
