Best Off-Road Trails in Southern California: Maps, Difficulty Ratings & Routes
Southern California offers some of the most diverse off-road terrain in the country. Within a few hours’ drive, you can go from crawling over granite boulders in the high desert to crossing wide-open sand washes below sea level. There are trails here for every skill level and every rig type, whether you’re looking for a mellow family cruise or a technical rock crawl that tests every inch of your suspension travel. The onX Offroad App helps you navigate this variety by letting you download Offline Maps, check public land maps and private land boundaries, identify Trail Difficulty Ratings, and mark Waypoints before you head out. This guide covers some of the best off-road trails across the region, organized by area, with honest difficulty assessments and practical route information.
Why Southern California Is an Off-Road Destination
The short answer comes down to geology and public land. Southern California sits at the intersection of multiple mountain ranges, vast desert basins, and thousands of square miles of BLM and national forest land open to motorized recreation. The San Bernardino National Forest alone has hundreds of miles of designated OHV routes. The Mojave Desert stretches north and east with seemingly endless trail networks. And then there’s the desert floor—places like Anza-Borrego, Johnson Valley, and the Imperial Sand Dunes, each offering a completely different riding experience.
The climate helps too. While riders in other parts of the country are putting their rigs away for winter, SoCal’s desert trails are entering prime season from October through April. The mountains offer summer riding when the desert gets too hot. All of this adds up to a region where you could ride every weekend for years and still not cover everything.

Understanding Trail Difficulty Ratings
Before diving into specific trails, it helps to understand how off-road trail difficulty is generally categorized. Most land management agencies and trail systems use some version of a numbered scale, but the descriptions below give you a practical sense of what to expect.
Easy trails are maintained dirt roads with gentle grades. You’ll encounter graded fire roads and smooth desert tracks. A stock 4×4 or high-clearance SUV will handle these without issue.
Moderate trails have some obstacles and uneven surfaces. Expect ruts, loose rock, and mild hill climbs. You’ll want 4WD with decent tires and some skid plate protection.
Difficult trails present significant obstacles and steep sections. Large rocks, ledges, deep sand, and tight switchbacks are common. A built rig with lockers, skid plates, and 33-inch or larger tires is recommended.
Expert trails involve technical rock crawling and extreme exposure. Boulder fields, shelf roads, and sections requiring extreme articulation define these routes. You’ll need a purpose-built rig, full recovery gear, and real experience behind the wheel.
When you’re scouting trails in the onX Offroad App, color-coded Trail Difficulty Ratings give you a quick visual read on what you’re getting into before you commit. That matters when you’re towing a trailer two hours into the desert and don’t want to discover at the trailhead that the route exceeds your rig’s capability.
Top Southern California Off-Road Trails
The Mojave Desert: Big Sky and Open Terrain
Johnson Valley is one of the most well-known OHV areas in California. Located north of Joshua Tree, it offers a massive network of trails across open desert terrain with rocky washes, sandy flats, and enough room to spread out.
The area is split into shared-use zones that are open year-round to motorized vehicles and portions that overlap with the Twentynine Palms Marine Corps base. The military sections are only accessible during certain times of year. Checking current open and closed dates before you go isn’t optional, it’s essential. The onX Offroad App can help you identify mapped access boundaries and restricted areas before the trip, reducing the risk of accidentally crossing onto military or other closed land. Always confirm current access rules with the managing agency.
Location: North of Joshua Tree National Park, San Bernardino County
Difficulty: Easy to Moderate for most open desert routes. Some rocky washes push into Difficult territory.
Best For: 4x4s, UTVs, dirt bikes, ATVs
The Hammer Trails area within Johnson Valley is where things get serious. If you’ve seen King of the Hammers coverage, this is where it happens. Trails like Aftershock, Wrecking Ball, and Chocolate Thunder are purpose-built rock crawling challenges. Don’t attempt these without a properly built rig and a spotter.
Just off I-15 between Barstow and Victorville, Stoddard Valley is a convenient option for riders coming from the Los Angeles basin. The terrain consists of rolling desert hills with a mix of sandy washes and rocky ridgelines. It’s popular with dirt bikes and ATVs, but there are plenty of 4×4 routes as well.
Location: Between Barstow and Victorville, off Interstate 15
Difficulty: Easy to Moderate
Best For: Dirt bikes, ATVs, UTVs, stock-to-mildly-built 4x4s
The area doesn’t have extensive formal trail signage, which makes reliable GPS navigation important. Download your maps before you leave home. Cell service is spotty at best once you’re out in the hills.
Calico Ghost Town and Surrounding Trails
Near Barstow, the trails around Calico offer a mix of desert scenery and old mining roads. Odessa Canyon and Mule Canyon are popular routes that wind through colorful rock formations and abandoned mine sites. The terrain is mostly moderate, with some tighter sections that require careful line selection in a full-size rig.
Location: Near Barstow, San Bernardino County
Difficulty: Easy to Moderate
Best For: 4x4s, UTVs
San Bernardino National Forest: Mountain Trails with Elevation
The Pinnacles Trail (3N10)
Running through the heart of the San Bernardino Mountains, the Pinnacles Trail is a classic SoCal 4×4 route. It connects several forest roads and climbs through pine forests with views of the surrounding valleys. The trail features rocky sections, moderate hill climbs, and a few tight spots between trees.
Location: San Bernardino National Forest
Difficulty: Moderate
Best For: 4x4s with decent ground clearance. UTVs can run portions, but check width restrictions.
This trail connects to other forest roads, making it easy to build a full-day loop. Use Route Builder in the onX Offroad App to plan your route ahead of time and mark Waypoints at key intersections. The forest road numbering system can get confusing when you’re at a five-way junction with no signs.
John Bull is one of the more technical trails in the San Bernardino National Forest. It’s a short but intense rock crawling route that drops steeply through a boulder-strewn canyon. This is not a trail you stumble onto by accident—or at least, you shouldn’t.
Location: San Bernardino National Forest
Difficulty: Difficult to Expert
Best For: Built 4x4s with lockers, 35-inch or larger tires, and skid protection. Not suitable for UTVs or stock vehicles.
Bring a spotter and recovery gear. The trail has several sections where a wrong line choice can put you on your roof.
Gold Mountain Trail (3N16)
Gold Mountain offers a solid moderate-difficulty route with rewarding views. The trail climbs to over 7,000 feet and passes through mixed terrain including packed dirt, loose rock, and a few ledgy sections. It’s a good step up from fire roads without jumping straight into rock crawling territory.
Location: San Bernardino National Forest
Difficulty: Moderate
Best For: 4x4s, capable UTVs
Anza-Borrego Desert State Park: Desert Beauty at Its Best
Anza-Borrego is California’s largest state park, and it’s remarkably off-road friendly. Hundreds of miles of dirt roads and trails wind through slot canyons, badlands, and palm oases. The landscape feels otherworldly—eroded mudstone formations, dry washes flanked by towering canyon walls, and wildflower blooms in spring that draw visitors from across the state.
Coyote Canyon is one of the park’s signature routes. The trail follows a sandy wash northward from the Borrego Springs area, passing through riparian areas and eventually climbing into the mountains. The lower sections are wide and sandy. The upper sections narrow and get rockier.
Location: Northern Anza-Borrego Desert State Park
Difficulty: Easy to Moderate (lower canyon), Moderate to Difficult (upper canyon)
Best For: 4x4s, UTVs (lower sections), dirt bikes
Portions of Coyote Canyon close seasonally, typically June 1 through September 30, to protect bighorn sheep and their water sources. Always verify current closure dates before heading out.
Fish Creek Wash and Split Mountain
This route takes you through some of the most dramatic geology in the state. The wash cuts through Split Mountain, where canyon walls tower hundreds of feet above you. The drive through the narrows is memorable, even at low speed.
Location: Southern Anza-Borrego Desert State Park
Difficulty: Easy to Moderate. The wash is mostly sandy and flat, but sections can get soft after wind events.
Best For: 4x4s, UTVs, high-clearance 2WD vehicles in dry conditions
Font’s Point is technically a single spur road rather than a full trail, but it deserves mention because the viewpoint at the end is one of the most striking in Southern California. The road crosses soft, sandy terrain for about four miles. It’s easy to get stuck if you don’t air down your tires.
Location: Anza-Borrego Desert State Park
Difficulty: Easy with proper tire pressure. Moderate if you try it aired up.
Best For: Any 4WD vehicle. Air down to 15-18 PSI and keep momentum through the soft spots.
The Imperial Sand Dunes (Glamis)
Glamis is a major destination for sand sport in the western U.S. The Imperial Sand Dunes Recreation Area stretches for over 40 miles along the California-Arizona border, and the dunes themselves reach heights of 300 feet or more.
This is a completely different kind of off-roading. There are no marked trails—just open sand. Navigation is about reading the terrain, understanding wind patterns, and knowing where the big drops and razor-back ridges are. It’s exhilarating, but it demands respect.
Location: Imperial County, along the California-Arizona border
Difficulty: Varies widely. Flat areas between dunes are easy. Climbing and descending dune faces ranges from Moderate to Expert depending on the dune.
Best For: Sand rails, UTVs, dirt bikes, ATVs. 4×4 trucks can handle the flats and smaller dunes but aren’t ideal for steep dune faces.
Glamis sees heavy use on holiday weekends, and accidents happen. Use a whip flag, ride with a group, and never crest a dune at full speed without knowing what’s on the other side. Recording your Track in the onX Offroad App helps you retrace your route and find your way back to camp when the dunes all start looking the same—which they will.
Inland Empire and Riverside County Trails
Located near Lake Elsinore, Corral Canyon is a popular spot for dirt bikes and ATVs. The trail network is well-maintained and offers a range of difficulties from beginner loops to steep, technical singletrack.
Location: Near Lake Elsinore, Riverside County
Difficulty: Easy to Difficult, depending on the specific trail
Best For: Dirt bikes, ATVs. Some trails are open to UTVs.
De Anza Trail
This historic route follows portions of the Juan Bautista de Anza National Historic Trail through the desert foothills east of Temecula. It’s more of a scenic backcountry drive than a technical challenge, but it’s a solid option for a half-day outing with the family.
Location: Riverside County, east of Temecula
Difficulty: Easy
Best For: Stock 4x4s, SUVs, UTVs
Los Angeles County and Surrounding Areas
Rowher Flat is one of the closest OHV areas to downtown LA, making it a go-to for riders who want to get out without a long drive. The area has designated trails for dirt bikes, ATVs, and 4x4s, with terrain ranging from smooth fire roads to rocky singletrack.
Location: Angeles National Forest, north of Santa Clarita
Difficulty: Easy to Moderate
Best For: Dirt bikes, ATVs, beginner-to-intermediate 4x4s
Pacific Crest and Mt. Gleason Roads
The fire roads in the Angeles National Forest offer miles of backcountry driving through the mountains above the San Fernando and San Gabriel Valleys. Routes like Mt. Gleason Road (3N17) climb to ridgeline elevations with panoramic views of the valley below.
Location: Angeles National Forest
Difficulty: Easy to Moderate
Best For: 4x4s, UTVs (check width restrictions on specific routes)
These roads can be affected by fire damage and subsequent erosion, so conditions change year to year. Check current trail conditions and closures before heading out.
Planning Your Trip: Practical Considerations
Seasonal Timing
Southern California off-roading is largely a year-round activity, but the best season depends on where you’re going.
Desert trails like those in Anza-Borrego, Johnson Valley, and Glamis are best from October through April. Summer temperatures in the low desert regularly exceed 110 degrees, which is dangerous for both you and your vehicle.
Mountain trails in the San Bernardino and Angeles National Forests are best from late spring through fall. Winter brings snow and ice to higher elevations, and many forest roads close seasonally.
Permits and Fees
Many OHV areas in California require a valid OHV Green Sticker or Red Sticker for competition-use vehicles. The California State Parks OHV Division manages these programs. National Forest areas may require an Adventure Pass for parking. BLM land is generally free to access, but specific recreation areas may have fees.
Recovery Gear Essentials
No matter where you ride, carry the basics: a tow strap or kinetic recovery rope, shackles, a tire repair kit with portable air compressor, a shovel, a first aid kit, extra water (at least one gallon per person per day in the desert), and a fire extinguisher.
Navigation and Maps
This is where preparation really pays off. Southern California’s trail networks are vast, and many routes cross through areas with zero cell service. Downloading Offline Maps before your trip means you always have a clear picture of where you are, what land you’re on, and how to get back.
The onX Offroad App lets you download detailed topographic and satellite maps for your entire trip area, including Trail Difficulty Ratings, public land maps, private land boundaries (Elite only), and available Trail Reports and photos that help you understand the route before you are on it. You can record your Track and drop Waypoints at camp spots, tricky intersections, or points of interest—all without needing a cell signal.
Frequently Asked Questions
Fish Creek Wash in Anza-Borrego is a solid starting point. The terrain is mostly flat and sandy, the scenery is striking, and the route doesn’t require specialized equipment beyond a 4WD vehicle with reasonable ground clearance.
It depends on the area. Most California State OHV areas require a Green Sticker or Red Sticker registration. National Forest areas typically require an Adventure Pass for day-use parking. BLM land is generally open, but check specific area requirements.
Most of Anza-Borrego’s trails are open year-round, but some areas—particularly Coyote Canyon—have seasonal closures to protect wildlife. Summer heat also makes desert riding inadvisable from June through September.
The Hammer Trails in Johnson Valley and John Bull Trail in the San Bernardino National Forest are among the most technical routes in the region. Both require purpose-built rigs, experienced drivers, and proper recovery equipment.
Trail status can change due to fire closures, seasonal wildlife protections, military operations, or weather damage. Review available Trail Reports and mapped trail information in the onX Offroad App, then confirm important closures with the local ranger district, state park, military installation, or BLM field office before your trip.
Hit the Trail With a Plan
Southern California’s off-road landscape is as varied and rewarding as anywhere in the country. From the wide-open sand of Glamis to the forested switchbacks of the San Bernardino Mountains, there is a route that can match your vehicle, skill level, season, and the kind of day you want to have.
Before leaving home, use the onX Offroad App to explore Featured Trails, review Trail Difficulty Ratings, and check available Trail Reports for recent conditions or obstacles. Route Builder can help you map a custom trip, while Waypoints make it easier to save trailheads, campsites, fuel stops, difficult intersections, and potential turnaround points.
Because cell service is unreliable across the desert and mountain trail systems, save Offline Maps for the entire area you plan to travel through. Offline Maps keep key map information and your GPS location available when service disappears. Public Land Maps and Private Land Boundaries can also help you understand the patchwork of BLM, national forest, state, military, tribal, and private land, but always confirm current closures, permits, and access rules with the managing agency.
Depending on your membership level, tools such as 3D Maps can help you preview elevation and surrounding terrain before committing to a route. The Dispersed Camping Map Layer can also help identify potential camping areas near your planned trails where dispersed camping information is available.
The key to a good trip is preparation. Know your route, understand the difficulty, check closures, carry recovery gear, and be willing to turn around when conditions or obstacles exceed your ability. Stick to designated trails, pack out what you bring in, and respect seasonal and emergency closures so these places remain open for the next generation.
Pick a route that fits your rig, save your Offline Maps, and head out prepared. With the right plan and the onX Offroad App available along the way, you can spend less time wondering where to go and more time exploring Southern California’s deserts and mountains.
