Hillside to Hollow Reserve
2690 N Harrison Hollow Ln
Hillside to Hollow Reserve is 260 acres off of Bogus Basin Road.
The Land Trust of the Treasure Valley (LTTV) acquired 58 acres in Harrison Hollow in 2011 with private donations. In 2013, the city of Boise purchased the adjacent 258 acres with serial levy funds. Combined, the two parcels have created a large protected open space area in the central foothills that citizens call “Hillside to the Hollow.”
Fencing project in Reserve March 7-11
To protect rare and native plants, reduce erosion and enhance wildlife habitat, fencing will be installed around the Hillside to Hollow Trailhead starting March 7, 2022. Work is estimated to take one week to complete. The City of Boise and Land Trust of Treasure Valley are both installing fencing at the same time in the reserve. This will not cause any trail closures but it will impact parking at the trailhead as there will be large equipment and supplies in the area.
Hours of Operation
Park is open from sunrise to sunset.
