Mission Trails Regional Park is an area that is rich in pre-European history from the Kumeyaay people, and an area that is rich in post-European history with the Old Mission Dam along with the remnants of Camp Eliott. Within the confines of its 7,220 acres are five mountains, which comprise a hiking challenge for adventurous locals and visitors alike. However, a little known historic fact is that the park actually has four - not five mountains. Earlier maps of the region called both South Fortuna Mountain and North Fortuna Mountain simply “Long Peak”. Even today, from a distance, the separate summits of South Fortuna (1,094 feet elevation) and North Fortuna (1,291 feet elevation) separated by the Fortuna saddle appear to be one mass with a number of humps. Despite visual appearances and former maps, even though South Fortuna is the smallest summit in the park, it can be a great strenuous day hike, as part of a larger trek, or as a stand-alone summit.
Mission Trails Regional Park (MTRP) is one of the best places to go hiking in the City of San Diego. Containing over 5,800 acres of open space, it is the largest city park in the State of California; and the seventh largest city park in the United States. Among many things, it contains the historic Old Mission Dam; beginner and intermediate rock climbing routes; and Cowles Mountain. Mission Trails, however, is more than just the Dam and Cowles Mountain - it is an area with over forty miles of hiking trails. While most of the park's visitors concentrate on the Eastern portions of the park - Cowles Mountain, the Old Mission Dam, the Grasslands Loop, and Kwaaypay Peak, there is also plenty of great hiking on the western side of the park without the crowds. A great intermediate hike is the Clairemont Mesa to Shepherd Pond route, which provides excellent views of the interior of the park, and slightly different terrain than a standard San Diego hike.
