Exploring the San Bernardino Mountains: An Overlander’s Paradise
The first time I ventured into the San Bernardino Mountains in my trusty 4×4, I wasn’t expecting to find such raw, untamed beauty just a few hours from Southern California’s bustling cities. Rising abruptly from the landscape, these mountains offer a rugged escape—a place where winding trails, dense pine forests, and rocky ridges challenge even the most seasoned off-roaders. Whether you’re an overlander looking for seclusion under the stars or an adrenaline junkie seeking technical trails, the San Bernardino Mountains deliver an experience unlike any other.
Why Overlanders and Off-Roaders Love the San Bernardino Mountains
There’s a reason why this region has become a must-visit for overlanders and 4×4 enthusiasts. The diversity of terrain, the historical significance, and the sheer number of trails make it an adventure-seeker’s dream.
A Diverse Landscape That Pushes Your Skills
One moment, you’re navigating soft, sandy washes that demand precise throttle control, and the next, you’re climbing rocky inclines that test your suspension and articulation. Some trails cut through thick pine forests where diff locks become your best friend, while others open up to breathtaking views of the Mojave Desert. This diversity ensures that no two trips to the San Bernardinos feel the same.
Take, for example, the John Bull Trail. Regarded as one of the toughest trails in the area, it’s not for the faint of heart. I remember attempting this route on a solo run, thinking my rig was well-equipped—only to realize halfway through that I had underestimated the steep rock ledges and deep ruts. It was a humbling experience, one that reinforced the need for thorough planning and the right gear.
A Rich History Beneath Your Tires
Driving through these mountains, you’re rolling over trails steeped in history. The San Bernardino Mountains played a crucial role during the California gold rush, with mining towns sprouting up in the 1800s. Today, remnants of that era—old cabins, abandoned mines, and rusting equipment—add a ghostly charm to your journey.
One such spot is Holcomb Valley, once a thriving gold mining settlement. As I set up camp near this historic area, I often find myself imagining what life was like for the early prospectors—braving harsh winters, surviving on sheer grit, hoping to strike it rich. It’s a reminder that these trails tell stories far older than our tire tracks.
Top Overlanding and 4×4 Trails in the San Bernardino Mountains
With trails ranging from mild to extreme, the San Bernardino Mountains have something for every level of off-roader. Here are some of the most noteworthy routes:
1. Cleghorn Ridge Trail
For beginners or those looking to shake down a new rig, Cleghorn Ridge is a great introduction to the region. It offers a mix of dirt roads and optional rocky side trails that serve as great training for more challenging terrain.
On one particular trip, I took a first-time overlander here to get familiar with terrain changes. Watching them go from nervous to confident—learning how to pick lines, adjust tire pressure, and keep steady throttle—was a perfect example of why Cleghorn is often called a ‘gateway’ trail.
2. Gold Mountain Trail
Stepping up in difficulty, Gold Mountain can be a solid test for a well-built rig. It has steep ascents, loose rock sections, and a few narrow passages that demand precise tire placement. The reward? Some of the most stunning panoramic views you’ll find in these mountains.
3. John Bull Trail
This is a true black diamond trail, demanding patience, proper gear, and an understanding of your rig’s capabilities. Massive boulders and technical sections make it ideal for experienced off-roaders.
On my last run through John Bull, I encountered an overlander in a well-modified 4Runner struggling with a particularly tricky rock section. With some spotter assistance and a bit of strategic winching, they conquered the obstacle—proof that teamwork and preparation can make or break a tough trail.
Best Camping Spots for Overlanders
A great overlanding trip isn’t just about the trails—it’s about where you settle once the sun dips below the ridgelines. The San Bernardino Mountains have some incredible dispersed camping areas that offer solitude and stunning scenery.
Holcomb Valley Campgrounds
Close to Big Bear, this location offers an excellent mix of developed campsites and dispersed options, making it perfect for those who want a little more flexibility.
Deep Creek Hot Springs
Imagine ending a long day on the trail with a soak in natural hot springs. While the hike down to the springs is a bit arduous, the experience is completely worth it.
Cactus Flats
For those who prefer wide-open spaces and fewer crowds, Cactus Flats provides an ideal overlanding basecamp with access to multiple trails.
Gear and Preparation for a Successful Trip
Gear can make all the difference between an unforgettable overlanding trip and a nightmare situation. Here are a few key things to keep in mind before heading into the San Bernardino Mountains:
Navigation is Key
Many trails here have multiple offshoots, making a GPS system or paper maps essential. Apps like Gaia GPS and off-road maps from OnX Offroad can help you stay on track.
Recovery Equipment is a Must
Even well-maintained trucks can get into sticky situations. A high-quality winch, recovery boards, a snatch strap, and a shovel should always be part of your kit.
Weather Can Change Quickly
These mountains are known for their unpredictable weather. A sunny day can turn into a rainstorm, making some trails impassable. Always check forecasts, pack appropriately, and be ready to adjust your plans.
Final Thoughts: The San Bernardino Mountains Are Waiting
There’s a reason overlanders keep returning to the San Bernardino Mountains. Beyond the thrills of technical trails, beyond the breathtaking summit views and peaceful campfires, there’s a sense that this place strips life down to its essentials. It teaches respect—respect for nature, for history, and for the machines that carry us into the unknown.
So, the next time you find yourself itching for an escape, grab your gear, fuel up your 4×4, and head for the San Bernardinos. Adventure is waiting just beyond the pavement.
