Follow the OHV route (2N33) for a rugged hike with dirt roads, rocky sections, and big views over Silverwood Lake and the surrounding hills from Pilot Rock. Expect moderate climbs, limited shade, and some loose footing—great for those wanting a backcountry feel close to Lake Arrowhead. Bring plenty of water and offline maps.

Box Springs Mountain Reserve is located on 3,400 beautiful acres of land that overlook the cities of Riverside and Moreno Valley. The Reserve once was covered in dense Coastal Sage Scrub, but recent wildfires have allowed non-native grasses to thrive. Visitors should be conscious of their activities while visiting the Reserve in order to protect wildlife and their delicate ecosystem.

Close to the suburbs of Los Angeles, the hike to Etiwanda Falls is short enough for a stroll, but takes away the stress of the big city. Especially on a hot day you will enjoy the shady canyon with the cool water besides the beautiful scenery. You can park your car at the North Etiwanda Preserve Parking Lot which is also the trailhead. The park opens at 6.30 a.m.
