Bommer Canyon to Butterfly Valley Hike

Join us as we explore the Irvine Open Space Preserve on this hike through Bommer and Shady Canyons. We’ll begin at the Cattle Camp, where ranch equipment of old still stands. After a steep ascent on the East Fork trail, we’ll make our way across part of Serrano Ridge and descend into Shady Canyon to the Butterfly Valley trail. Here, you’ll experience some of the most mature Coastal Sage Scrub in all of Orange County. After a short stop we’ll return the same way. Total round trip distance is 9 miles with an elevation gain of 1500 feet at an average moving rate of 2.5 miles per hour. All participants must carry their own water! Please come prepared with a pack, plenty of water, snacks, sturdy closed-toe hiking shoes or boots, sunscreen, first aid, and all other supplies to keep you safe and healthy on the trail. Under-prepared participants may be denied access to the event!
