San Diego County is one of the best regions in the United State for off-roading, featuring abundant off-road trails ranging from mellow dirt roads to hard-core rock crawling trails.
In this guide, we’ve curated a running list of San Diego off-road trails that will suit drivers of varying skill levels. Whether you are looking for a hardcore Jeep trail or a chill dirt road for daily-driver SUV, we’ve got you covered.
To make it easier to navigate, we’ve grouped the off-road trails into different destinations. Where we have separate guides to areas, you can follow links to those to learn more. We’ll provide an indication of difficulty for each trail, but please know that this isn’t an official grading system at all. We recommend exploring these trails with someone whose done them before and has experience off-roading.
If you are just getting started or looking for people to go wheelin’ with, San Diego has several off-roading clubs that are great places to meet other off-roading and overlanding enthusiast. Also, we recommend getting appropriate training in off-road safety, driving, and recovery. The clubs can be a great resource for getting this training.
Lastly, before we jump into the list, please know that it is a work in progress. There are MANY trails in San Diego. While we hope to get to them all eventually, it’s gonna take a while!

Nate Harrison Grade Trail
Nate Harrison Grade Trail is a gravel and dirt truck trail in San Diego County that winds from Pauma Valley to the top of Palomar Mountain. The steep 9.5-mile road, which offers stunning views of the surrounding landscape, is popular among off-roading and overlanding enthusiasts, mountain bikers, and hikers (to a lesser extent).
The road ascends 4,600 feet over 9.5 miles at an average grade of 8 percent, with some sections much steeper than that. See our full guide to Nate Harrison Grade Trail for more details.
Palomar Divide Truck Trail
Palomar Divide Truck Trail is a truck trail that traverses the northeastern margin of Palomar Mountain. The route combines Palomar Divide Truck Trail and High Point Truck Trail but is generally referred to as the former.
This is one of the easier routes on our list but offers stellar views and a beautiful natural environment to explore. You will still want a capable SUV or, even better, a high clearance 4-wheel-drive vehicle. The elevation here gets as high as around 5000 feet, and the ecosystem is much more alpine in feel than other parts of Southern California, including tall forests of pine and cedar.
The road can be accessed from a number of points. One popular entry point is the intersection of High Point Truck Trail and Highway 79, near Rancho California RV Resort (GPS: 33.440413, -116.857018). From there, High Point Truck Trail will bring you up to near the top of Palomar Mountain where it will merge with Palomar Mountain Truck Trail (the intersection is located at 33.362666, -116.826517).
From there you can head right, to explore the lovely Doane Valley and other areas at the top of Palomar Mountain, or head left and Palomar Mountain Truck trail will eventually bring you back to 79.

Valley of the Moon Off-Road Trails
Located in the Jacumba Mountains east of downtown San Diego, Valley of the Moon is popular among off-roading enthusiasts and rock climbers. The area is managed by the Bureau of Land Management and part of the area, the Jacumba Wilderness, is protected as wilderness areas (so no vehicles allowed).
The entrance road to the area climbs steeply from a staging area just off I-8. It’s semi-paved but has quite a few potholes and some rocky areas that at a minimum are best traversed in a vehicle with a bit of clearance, such as a Subaru or other SUV.
Past the top of this entrance road, about 1.4 miles in, you’ll want a high-clearance four-wheel drive, such as a Jeep, Toyota 4-Runner, or pickup truck to continue.
Elliot Mine Trail
Elliot Mine (GPS: 32.623187, -116.080622) is located on the top of Tehe’ Peak and is a popular destination for people exploring the area by foot or 4-wheel-drive vehicle. The summit of Tehe’ offers a terrific 360-degree view of the Valley of the Moon and into Mexico.
Elliot Mine is deep into the Valley of the Moon area, though still just outside of the Jacumba Wilderness area. It’s about a 3-mile drive or hike from the trailhead just off 1-8. The trail up the hill (Trailhead GPS: 32.624096, -116.081107) from the valley to the mine is a narrow, rough, and precipitous off-road trail for capable 4-wheel drive vehicles only.
Halfway up the hill to the mine, where the trail bends sharply to the right, there is room to turn around or to park and walk the rest of the trail to the top of the mountain. It’s possible to drive all the way to the top, but we’d recommend scouting the trail first to make sure you’re up for it.
Otay Mountain Wilderness Trails
Otay Mountain Truck Trail is an off-roading route in the Otay Mountain Wilderness, an backcountry area along the Mexican border in southern San Diego County. This is one of the more accessible off-road areas near the city of San Diego and offers 17,000 acres of rugged mountain terrain to explore.
While the main truck trail is well-groomed and heavily patrolled by U.S. Customs and Border Patrol agents, there are off-shoot trails that offer technical challenges for capable vehicles and drivers.
