At 1,291 feet high, North Fortuna Mountain is the third highest mountain in the confines of Mission Trail Regional Park and is 197 feet higher than its neighbor, South Fortuna Mountain. In my mind, however, out of all of the five mountains in the park, North Fortuna Mountain features the toughest leg burning ascent. Like many things, this is something that is open to debate. While both Cowles Mountain and Pyles Peak for the most part do not feature tough straight uphill sections, both South Fortuna and Kwaay Paay Peak have solid claims to the toughest leg burning ascents as well. Even with the toughest - or near toughest leg burning ascent, North Fortuna Mountain is a great hike as it provides great views, and is part of the Five Peak Challenge within Mission Trails.
