You already know how to climb South Fortuna Mountain so in this post, we’ll look at its taller neighbor: North Fortuna (elevation 1,291), the third highest peak in Mission Trails Regional Park, behind Cowles and Pyles. Many hikers combine the two Fortunas into one big trek and while that’s a challenging and worthwhile endeavor, hiking to North Fortuna via Oak Canyon, described below, offers variety. In fact, the combination of Oak Canyon’s peacefulness (especially during the winter months when the sound of the trickling stream enhances the experience) and panoramic views from the summit make this arguably the best hike in the park.

From the parking area, head past the Old Mission Dam (note the historical marker and the fact that the dam was completed more than 200 years ago), cross the river on a narrow footbridge and begin hiking on the Oak Canyon Trail. Oak Canyon is a pleasant riparian habitat which is not entirely shaded but is nevertheless home to several impressive live oaks as well as a seasonal stream. Make your way up canyon, occasionally crossing a footbridge, staying left at two intersections and negotiating a rocky gorge. At 1.1 miles from the start, bear left on the North Fortuna Summit Trail. Follow it a short distance to a junction (the start of the loop).

The loop portion of the hike is more easily done counter-clockwise, as described below. Head right (north) on a single-track, signed as Oak Canyon North. You’re likely to have less company in this more remote section of the trail; other than the 52 Freeway overpass in the distance, there aren’t many signs of civilization. After a final stream crossing, the trail climbs the rocky eastern wall of the canyon and reaches a T-junction by an information board.

Turn left and head uphill on a dirt road. The next 3/4 mile is the only part of the hike that might feel like work as the trail makes a steep, exposed ascent. However, even this stretch has its rewards; keep an eye out for a small scenic waterfall shortly after the first climb and enjoy increasingly wide views to the north and east. When the dirt road ends, turn left on a single-track which climbs up a staircase and reaches the toe of North Fortuna Mountain’s north ridge (2.7 miles from the start.)

Follow the trail north (left) toward the summit, climbing an exposed ridge for 0.4 mile and 300 vertical feet, passing a false summit on the way. After some huffing and puffing, you’ll find yourself on North Fortuna Mountain, with a 360-degree view: South Fortuna, Cowles and Pyles to the south; San Diego and the ocean to the west; Mt. Woodson and Iron Mountain northeast. You may even get a glimpse of the distant San Jacinto and San Bernardino Mountains.

After enjoying the view, continue south on the trail which is level for a few hundred feet before dropping steeply down to Fortuna Saddle (3.7 miles from the start). Turn left and begin another steep, sometimes loose descent, dropping back down into Oak Canyon, completing the loop. Retrace your steps on the Oak Canyon Trail back to Old Mission Dam and your starting point.
