Recharge your batteries with a refreshing mid-week hike through Bommer Canyon. This area was historically a center for cattle operations that occurred in the San Joaquin Hills up until the late 1990s, and is now being restored to native habitat.

This hike involves multiple steep climbs and descents across a variety of trail types, including some narrow singletracks, with 2200+ feet of accumulated climbing elevation, but is done at a moderate pace, approximately 3 mph. Please bring plenty of water, and wear sturdy shoes. Hiking distance is 10-12 miles.

Park staff is requesting assistance from Park Ranger Reserves to help enforce “Do not feed the squirrel” regulations at Mile Square Park. Due to the feeding of park wildlife by the public, the squirrel population at the park has become extremely brazen. Ranger Reserves are needed to conduct vehicle and foot patrols to educate and advise the public about not feeding the wildlife.
