This route was planned by komoot.
As an OHV road, access points are typically found along its length, particularly where it enters Bureau of Land Management (BLM) land and the Mendocino National Forest. Specific parking areas are not detailed, but hikers often find suitable spots at various entry points along the route. Plan to park responsibly and ensure you are not blocking any access roads.
The trail is rated as difficult by komoot and described as 'somewhat rough' with rutted and rocky sections. While manageable on foot, its length (up to 31 miles) and challenging terrain make it more suitable for hikers with some experience. Beginners should consider shorter sections or be prepared for a strenuous outing.
Expect a full-width dirt and gravel road that is often rough, with highly rutted and rocky sections. You'll encounter loose dirt, rocks, and potentially large holes that can fill with water after rain. The route is winding, with some narrow sections. There is at least one small water crossing. Elevations can reach over 4,000 feet.
Spring and fall are generally the best times to hike. Spring may offer wildflowers and milder temperatures, while fall provides cooler weather. During winter, ice and snow are common at higher elevations, potentially making the road impassable. Summers can be very hot, so plan accordingly with plenty of water.
Yes, dogs are generally permitted on this trail, which traverses Bureau of Land Management (BLM) land and the Mendocino National Forest. It's always a good practice to keep your dog on a leash and ensure you pack out any waste to preserve the natural environment.
No, there are typically no permits or entrance fees required to hike Bartlett Springs OHV Road, as it passes through Bureau of Land Management (BLM) land and the Mendocino National Forest, which are generally free to access for day use. Similarly, the Berryessa Snow Mountain National Monument does not have a general entrance fee, though specific developed recreation sites within it might have fees.
The trail offers excellent and breathtaking views throughout. From higher vantage points on a clear day, you might spot the Sutter Buttes over 50 miles in the distance. The landscape features interesting rock formations and leads towards Indian Valley Reservoir. You can also encounter the ruins of the historic Bartlett Springs Resort, a once-thriving health retreat.
Yes, the route provides access to numerous offshoots and other service roads within the Mendocino National Forest. Specifically, the Bartlett Springs OHV Road also passes through sections of the Minor Road, Tully Road, 15 North 19 Road, Denton Road, and 15 North 05 Road, offering opportunities for varied exploration.
Given the trail's length and rough terrain, it's essential to bring plenty of water, sturdy hiking boots, sun protection (hat, sunscreen), and layers of clothing for changing weather. A map or GPS device is highly recommended due to the numerous intersecting roads. Snacks, a first-aid kit, and trekking poles can also be beneficial.
The Bartlett Springs OHV Road is primarily a long, linear route, making it an out-and-back experience if you traverse its full length. However, its numerous offshoots and intersecting service roads within the Mendocino National Forest allow for creating various loop options or shorter, customized hikes.
Beyond hiking and trail running, the area offers a wide range of recreational opportunities. You can enjoy camping, mountain biking, fishing, hunting, and recreational shooting. The Mendocino National Forest, which the trail traverses, is unique as California's only national forest not bisected by a paved road, offering a truly wild experience.
