Sure, Pleasanton Ridge sounds like the name of a subdivision—and it probably is, somewhere. But it’s also a 5,271-acre East Bay regional park, and home toone of the best long hikes in the Bay Area.
This 12.3-mile loop tours the length of the park, gaining 3,000 feet and offering stunning views of Mt. Diablo, Mission Peak, and the Sunol/Ohlone Wilderness. It’s one of the toughest hikes in the area, and follows almost every trail in the park.
