Irvine Ranch Natural Landmarks

Grab your day pack and join us on a distance hike through scenic Bommer Canyon and beyond into Laguna Coast and Crystal Cove Parks. We stage at Cattle Camp, historically a center for cattle operations that occurred in the San Joaquin Hills up until the late 1990s, and now part of the Irvine Open Space Preserve. 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 (100 oz. recommended), and wear sturdy hiking shoes. Hiking distance is 10-12 miles.

All participants must carry their own day pack and water! Please come prepared with a pack, sturdy closed-toe hiking shoes or boots, sunscreen, first aid, and all other supplies to keep you safe and healthy on the trail for the half-day of being out in the wilderness area. Under-prepared participants may be denied access to the event! Program may be cancelled or shortened due to adverse weather conditions.

Please arrive 15 minutes early, ready to hike; the Cattle Camp entry gate will close promptly at 6:55 a.m.
