Back Bay Loop Trail
--OPEN DAILY--
Upper Newport Bay is one of Southern California’s premier recreational and environmental treasures. The Back Bay Loop Trail provides an exciting opportunity for outdoor enthusiasts to discover a magnificent regional trail experience and get to know the Bay. The 10.5-mile trail is well-signed as it winds around the Bay, with scenic stops at places like Upper Castaways Park, the County of Orange’s Peter and Mary Muth Interpretive Center, the new Back Bay Science Center at Shellmaker Island, and Big Canyon. The Back Bay Loop Trail also links to the 22-mile Mountains to Sea Trail. This scenic trail – designated a National Recreation Trail by the National Park Service – runs from Upper Newport Bay through Irvine past Peters Canyon Reservoir and into the rugged mountains of Weir Canyon north of Irvine Regional Park.
