The Laguna Mountains are a section of the Peninsular Ranges in eastern San Diego County, California. The mountains run in a northwest/southeast alignment for approximately 20 miles (32 km).
The Laguna Mountains are bordered by the Cuyamaca area on the west and the Colorado Desert on the east, where the mountains form a steep escarpment along the Laguna Salada Fault. To the north the Laguna Mountains are bounded by the Elsinore Fault Zone and to the south by Cameron Valley and Thing Valley. The highest point is Cuyapaipe Mountain at 6,378 feet (1,944 m). The mountains are largely contained within the Cleveland National Forest. Snow falls on the highest peaks several times a year. Mount Laguna is a village in the Laguna Mountains with a population of about 80.
The Laguna Mountains extend northwest about 35 mi (56 km) from the Mexican border at the Sierra de Juárez range. The Santa Rosa Mountains are to the northwest.
