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.”
