Mountains to Sea Trail, Southern California

The trail runs 22 miles through open space preserves in the suburban landscape south of Los Angeles.

From the Irvine Ranch Land Reserve Trust
Designated as a National Recreation Trail in 2006

Your journey begins with a docent-led hike in rugged, oak-filled Weir Canyon. It then takes you south through six jurisdictions— five cities and a portion of the County of Orange— guaranteeing that the only constant on this trek is an exhilarating change of scenery and topography.

The Mountains to Sea Trail— the backbone of the 50,000-acre Irvine Ranch Land Reserve— was created through cooperative municipal planning to let people of all ages and abilities experience unimpeded the magnitude, magnificence and diversity of the Reserve.

From Weir Canyon to Irvine and Peters Canyon Regional Parks, past the historical Irvine Ranch agricultural headquarters and along the San Diego Creek Channel to Upper Newport Bay, there's no more enjoyable way to experience one of the nation's most spectacular networks of parks, trails and preserved natural lands.

Activities allowed on the trail include hiking, running, and walking; equestrian riding; and bicycling. Interesting areas along the trail and open space include Weir Canyon Wilderness Area, Irvine Regional Park, Peters Canyon Regional Park, San Joaquin Wildlife Sanctuary, and Upper Newport Bay.

The trail runs through the Cities of Anaheim, Orange, Tustin, Irvine, Newport Beach, and the County of Orange. The trail managing agency is the Irvine Ranch Land Reserve Trust.
