Ontario Peak

Watch for the summit spur or you'll overshoot to Etiwanda Peak
Very exposed after 10am, start early for shade
Roughly 13 miles roundtrip with 3,700 feet elevation gain

Tight switchbacks wind through pines to an 8,858-foot summit with sweeping views of Bighorn Mountain and beyond. Easy to miss the short spur to the actual peak, so keep your eyes peeled.
