Cuyamaca is a region of eastern San Diego County. It lies east of the Capitan Grande Indian Reservation in the western Laguna Mountains, north of Descanso and south of Julian. Named for the 1845 Rancho Cuyamaca Mexican land grant, the region is now dominated by the 26,000-acre (110 km2) Cuyamaca Rancho State Park. Within the park is the prominent Cuyamaca Peak, the second-highest mountain in San Diego County at 6,512 feet (1,984.9 m).
