Hot Springs Mountain is the tallest peak in San Diego County at 6,533 feet. Despite this distinction, it receives light visitation compared to Cuyamaca Peak (the county’s second tallest) and other major San Diego area summits. This is perhaps due to its remote location and the fact that for a while, the summit was closed to the public by the Los Coyotes Indian Reservation.

This write-up describes the longer route from Los Coyotes Campground. (If the roads are open to Nelson Camp, a shorter hike is possible). Some hikers may find their patience tested on the first half of the route, which climbs steadily over exposed terrain, but the payoffs include a pleasant jaunt through a mixed alpine forest, panoramic views from the top and a sense of isolation that is rare in San Diego County or indeed all of So Cal. Additionally, for San Diego peak baggers, this is an essential summit.

The route starts at the northern end of the campground at a dirt road fenced off by a metal chain. A sign on the tree identifies this trail as Rough Road, although it’s listed as Sukat Road on Google Maps. After climbing out of the wooded area of the campground, the road makes a no-nonsense ascent, picking up about 1,300 feet in two miles. Once you have gained the top of the ridge, the grade levels out dramatically and you find yourself in an attractive woodland of black oaks, Jeffrey pines and incense cedars.

At 2.5 miles, you reach a junction with Hot Springs Road, a dirt road coming up from the entrance station. Bear right and continue north, dropping briefly into a ravine to meet the trail coming up from Nelson Camp (3 miles). Soon after the trail climbs out of the woods and you get some excellent views to the south and west, notably of the north Palomar slopes. The trail then re-enters the woods, where you may get your first glimpse of the summit between the trees. At 4.4 miles the trail makes a hairpin right turn and you begin your final ascent to the top.

The most distinctive feature on the summit is the long-abandoned lookout tower. It doesn’t take a degree in engineering to know that climbing the tower is unsafe, but you can still sit at the base and enjoy some wide-ranging views: the Palomars and Cuyamacas to the south; the Santa Rosas and San Jacintos to the north and the Santa Anas to the northwest. The true summit lies to the east and can be reached via some moderate bushwhacking and scrambling.

After enjoying the view and not climbing the tower, retrace your steps. On the way down, especially at sunset, the views are excellent; having sweated through them on the way up you will be able to enjoy them more with gravity working in your favor.

  1. Did you have any trouble with swarms of eye gnats on this Hot Springs Mountain hike? In August I did this hike and I and other hikers doing this hike were plagued by them . . . .
