Mission Trails Regional Park spans over 8,000 acres, preserving the natural landscape of San Diego as it existed before Juan Cabrillo's arrival in 1542.

Mission Trails Regional Park, located just eight miles northeast of downtown San Diego, offers a swift natural escape. It's considered the "third Jewel" in San Diego's Parks system, alongside Balboa Park and Mission Bay Park, providing residents and visitors access to the city's natural, cultural, historical, and recreational opportunities.

Started in 1974, Mission Trails Regional Park has become one of the largest urban parks in the United States. The park is home to the historic site of the Old Mission Dam, built to store water for the Mission San Diego de Alcala.

With about 60 miles of trails, boating on the City's Murray Reservoir, camping at Kumeyaay Lake, numerous informative hikes and a state-of-the-art Visitor and Interpretive Center, Mission Trails Regional Park has something to offer everyone.
