Located in the urban core of Tucson, the 100-Acre Wood Bike Park sits on a 100-acre parcel adjacent to an Air Force base — which is precisely why the land escaped development and still feels like genuine Sonoran Desert despite 60,000 residents living in the immediate area. The park features approximately 10 miles of trails built as a stacked loop system, inspired by the open, flowing design of nearby Fantasy Island Mountain Bike Park. The site is divided into 10 ecosystem zones that double as nature restoration areas, and the trails are named after local flora and fauna found on the property.
The park is purpose-built for skills progression, and that intention is baked into every design decision. A series of dedicated skill stations anchor the experience — each one includes a featured obstacle, a ride-around option for those not yet ready to commit, and signage with riding tips, plus a selfie station where a rider or coach can mount a phone to capture video for feedback. Five shaded regrouping rest points are spaced throughout the park, each featuring dual-use rock seating designed to double as rideable technical features, so faster riders can keep sessioning while they wait for the group to catch up. Of the park's roughly 10 miles of trail, 4.5 miles are designated as accessible to Adaptive MTB riders.
For Tucson, this bike park fills a gap that's long been obvious: most of the trails in this desert town are raw and rough, making the learning curve brutal for newcomers. The 100-Acre Wood offers a deliberate stepping stone — a place where beginner and intermediate riders can build real skills before graduating to the rugged stuff the region is known for. Parking is available at the nearby Todd M. Harris Sports Complex and Freedom Park Center, both of which connect to the bike park via the Aviation Bikeway.

This is for phase 1 of the project, which while short offers a great bit of riding close to downtown Tucson. There is no elevation gain and the builders have placed a large amount of twisting trail. There is a jump section with beginner and intermediate jumps. You can access the trails from the bike path near Davis Monthan Air Base and Alvernon Way. There is a facebook page for the park that will give you the most up to date info as well as the website www.sdmb.org if you are considering joining. I look forward to riding here more.
