The Bristlecone Trail is an easy, mostly flat route through mixed conifer forest near Snow Summit in Big Bear Lake. The main out-and-back along Bristlecone Road (Forest Road 2N99) covers about 2.8 miles round trip with minimal elevation gain — roughly 130 feet — making it one of the most accessible hikes in the Big Bear area for dogs and their people.
Dogs are welcome on leash (six feet maximum per San Bernardino National Forest rules). Pack out all pet waste — there are no waste stations at the trailhead, so come prepared with bags.
Starting from the trailhead on Willow Avenue, the wide dirt path winds through Jeffrey pine, ponderosa, white fir, and lodgepole pine at about 7,000 feet elevation. The route passes Pineknot Family Campground and Buttercup Group Campground before reaching the Bear Mountain Golf Course area. Despite the name, you won’t find bristlecone pines here — those ancient trees live in the White Mountains farther north. What you will find is a quiet, shaded forest walk with views toward Snow Summit’s ski runs and plenty of squirrels and mule deer to keep your dog interested.
The main trailhead is at 42789 Willow Avenue, Big Bear Lake, with a second access point off Club View Drive near Bear Mountain Golf Course. A National Forest Adventure Pass ($5 day / $30 annual) is required for parking. Parking can fill up on summer weekends, so arrive early or visit on weekdays if you can.
Bristlecone connects to the Pine Knot Trail system and Fern Trail via the Bristlecone Connector, and links to the Skyline Trail along the ridge above Snow Summit. Ambitious hikers can combine routes for a longer loop, but the Bristlecone out-and-back alone is a satisfying morning walk.
No restrooms or water at the trailhead — bring your own water for both you and your dog. The nearby Pineknot Campground has restroom facilities if needed. Best season is May through October; winter snow can close forest roads. The trail is shared with mountain bikers and equestrians, so keep your dog close and be ready to step aside when you hear bikes approaching.
