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.
