Upper and Lower Bristlecone Trail Loop

It's crucial to know that the upper portion of the Bristlecone Trail, up to the junction with the Bonanza Trail, is currently closed due to extensive damage from Tropical Storm Hilary in August 2023. The U.S. Forest Service anticipates this section will remain closed until 2029. While the lower part of the trail may be open, always verify current conditions and closures before planning your trip.

The trail offers varied terrain, transitioning between wide paths and narrower singletrack. Sections follow an old service road, providing a more gradual grade, while others are woodland foot trails. You'll also need to walk about 0.75 to 1 mile on the paved Lee Canyon Road (SR 156) to connect the upper and lower trailheads and complete the loop.

You'll experience diverse and picturesque scenery, including pine-fir forests, dense Aspen Grove, and ancient bristlecone pines, especially visible in higher elevations and along Highpoint Ridge. The trail also offers grand vistas of surrounding peaks like Mummy Mountain and Lee Peak, as well as expansive views down Lee Canyon from the Mummy Mountain Viewpoint.

Yes, the trail is generally dog-friendly. However, always ensure your dog is on a leash and that you pack out all waste to help preserve the natural environment and respect other hikers.

The trail is particularly beautiful in the fall when the quaking aspens turn vibrant yellow and red. It also offers cooler temperatures, often 20 degrees lower than the Las Vegas valley, making it a popular escape from the desert heat during warmer months. Be aware that winter conditions can bring snow, making parts of the trail more challenging.

No, there are no specific permits or entrance fees required to hike the Upper and Lower Bristlecone Trail Loop, as it is located outside the wilderness area. However, it's always a good idea to check the U.S. Forest Service website for any updated regulations or advisories for the Spring Mountains National Recreation Area.

Parking is available at the trailheads in Lee Canyon. Given the current partial closure, it's best to check the U.S. Forest Service website for the most up-to-date information on accessible parking areas and trail access points.

Hikers have the chance to observe unique wildlife, including the endemic Mt. Charleston chipmunks and rare butterfly species. Remember to keep a respectful distance and never feed wild animals.

Yes, the route also passes through sections of the Lower Bristlecone Trail, Upper Bristlecone Trail, and Forest Road 72. The currently closed upper section of the Bristlecone Trail extends up to the junction with the Bonanza Trail.

Some sources suggest starting from the lower trailhead for an easier initial ascent. This can help manage the moderate elevation gain more comfortably, especially if you're not accustomed to higher altitudes.

The Bristlecone Pines found along this trail are exceptionally long-lived trees, with some specimens being thousands of years old. Witnessing these ancient trees, particularly in higher elevations and along Highpoint Ridge, is a primary draw of this hike.
