Mount Laguna is a small census-designated place (CDP) in San Diego County, California. It is located at almost 6,000 feet above sea level in a forest of Jeffrey pine, east of San Diego in the Laguna Mountains on the eastern edge of the Cleveland National Forest. The hamlet sits at the high point of a scenic drive on Sunrise Highway from Interstate 8 to Highway 79. Mount Laguna consists of a small general store, rustic lodge and cabins, local restaurant, rural post office, and campgrounds adjacent to the Pacific Crest Trail. The Laguna Mountain Recreation Area surrounds the village, and the visitor's center for the pine-covered area is located here. The mountain backcountry of San Diego County is high enough to receive snowfall in winter months, and the Mount Laguna region offers locally-unique winter recreation in the form of snow play, sledding, and cross country skiing for several days after larger storms. The population was 57 at the 2010 census.
