The Irvine Ranch Natural Landmarks stretch in a giant green crescent from Weir Canyon near the 91 Freeway at the north end of the Irvine Ranch… connect with the Cleveland National Forest along the ranch’s northeastern border… continue south where they include the massive regional open space network in the northern and southern hillsides of Irvine… and extend all the way to Laguna Coast Wilderness Park and Crystal Cove State Park near Laguna Beach..

Scuba divers, snorkelers, surfers, swimmers, mountain bikers, joggers, hikers and equestrians all find something to do here. Crystal Cove State Park also features historic cottages, perfect for a trip back in time to last-century on the Southern California Coast and unique beachfront dining at the Beachcomber cafe or Crystal Cove Shake Shack.

The expansive northern region of the historic Irvine Ranch — adjacent to the Cleveland National Forest and the communities of Orange, Anaheim, Tustin and Irvine, contains more than 20,000 acres of permanently preserved open space and rare natural habitats.

These lands form a giant swath of open space stretching east from Gypsum Canyon to the Cleveland National Forest, and contain remote canyons, free-flowing watersheds, and important wildlife corridors that allow animals to move around the landscape.

The Mountains includes Weir, Blind, Fremont, Gypsum, Limestone, and portions of Baker, Silverado and Modjeska canyons. Loma Ridge, in north Irvine, preserves natural hillside views from the entire valley below. Besides its sheer expanse, the area is rich in biological diversity and supports an unusually diverse number of rare and endangered wildlife, plants and geological formations.
