You can find convenient parking at the Archery Range Parking, which provides direct access to the Military Reserve trails.
The loop combines sections of the Three Bears and Two Point Trails. The Three Bears section is known for its three steep climbs, including a particularly rocky and challenging 'Papa Bear' section. You'll also experience a fun, fast downhill with open sight lines. The Two Point Trail portion is a singletrack connector, generally easier with less elevation change. Expect a mix of dirt, some rocks, and limited shade throughout the route.
While the Two Point Trail section is rated as easy, the Three Bears portion of this loop is considered moderate to challenging due to its steep climbs and rocky sections. It requires good fitness, especially for the ascents. Beginners might find the climbs demanding, but experienced riders will enjoy the challenge and the fast downhill.
Generally, there are no specific permits or entrance fees required for mountain biking on the public trails within the Boise Foothills, including the Military Reserve. However, it's always a good idea to check the official Ridge to Rivers website for any updated regulations or temporary closures before your ride.
Yes, dogs are generally allowed on the trails within the Military Reserve and Boise Foothills. However, they must be kept on a leash, and you are responsible for cleaning up after your pet. Always check for specific signage or seasonal restrictions that might apply.
Spring and fall are typically the best seasons for riding this loop, offering cooler temperatures and pleasant conditions. Summers can be hot, and the limited shade on parts of the trail means you should plan for early morning or late afternoon rides during warmer months. Winter riding is possible, but be mindful of snow, ice, and muddy conditions.
The Boise Three Bears trail offers views into the middle and upper foothills. While the route doesn't have extensive unbroken scenic vistas, you'll experience the natural beauty of the foothills with open sight lines on descents and the distinct challenge of the 'bear' climbs.
Yes, this route utilizes several official trails within the Military Reserve and Boise Foothills. You'll ride sections of the #20A Bucktail, #26 Three Bears, #44 Two Point, #22 Central Ridge, and #20 Ridgecrest trails as part of this loop.
The Military Reserve is located close to Boise's urban areas. You'll find numerous cafes, restaurants, and pubs within a short drive from the Archery Range Parking area, particularly in downtown Boise or the surrounding neighborhoods.
Given the varied terrain and potential for steep climbs and descents, wear appropriate mountain biking attire, including a helmet, gloves, and sturdy shoes. Bring plenty of water, especially on warmer days, as there is no water available directly on the trail. Sunscreen, snacks, a basic repair kit, and a map or GPS device are also recommended.
Due to the challenging climbs and rocky sections on the Three Bears portion, this loop might be too difficult for younger children or beginner family riders. However, families with older, experienced mountain bikers who are comfortable with moderate to difficult terrain could enjoy the adventure.
