The San Joaquin Marsh & Wildlife Sanctuary, a 300-plus acre coastal freshwater wetland with 12 miles of trails for walking and running. It's also a bird paradise with hundreds of species.
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.
The preserved open spaces on The Irvine Ranch are beautiful, environmentally valuable and accessible to millions of people. The land encompasses 50,000 acres stretching 22 miles from the mountains to the sea, including the Mountains to Sea Trail. These lands have been named a Natural Landmark by both the U.S. Department of the Interior and the State of California.
