Otay Mountain Wilderness

The Otay Mountain Wilderness is a U.S. wilderness area in San Diego County, California, 12 miles east of the community of Otay Mesa and just north of the Mexico–United States border. Some parts of the wilderness area rise quickly from sea level, reaching a peak of just over 3,500 feet (1,100 m) at the summit of Otay Mountain.

Wilderness status was conferred on October 7, 1998, effectively preserving 18,500 acres under protection of the Wilderness Act, a component of the National Wilderness Preservation System. The legislation was signed by President Bill Clinton on December 11, 1999. The wilderness is managed by the Bureau of Land Management.
