When most people think of road trips from San Diego, they picture the well-trodden highways to Los Angeles or the glitzy coastlines of Big Sur. But California’s hidden corners hold some of the most rewarding adventures—perfect for those seeking a quieter, more authentic slice of the Golden State. Whether you’re cruising solo, exploring with friends, or embarking on a family adventure, these five lesser-known routes will make you fall in love with the open road all over again.
If you haven’t already, this is the perfect excuse to look into a San Diego camper van rental—your ticket to freedom, flexibility, and comfort as you explore the secret side of California.
1. The Mountain Magic of Sunrise Highway
Route: San Diego → Mount Laguna → Julian → Cuyamaca Rancho State Park
Just east of San Diego lies a stretch of road that feels worlds away from city life. The Sunrise Highway (State Route 79) offers stunning views of the Anza-Borrego Desert and sweeping panoramas from over 6,000 feet above sea level. In fall, the oak forests near Julian glow in shades of amber and gold, and in winter, you might even catch a dusting of snow—something few expect so close to the beach.
Spend the night at Burnt Rancheria Campground, then roll into Julian for a slice of its famous apple pie. It’s an ideal mini adventure for families testing out their first family van rental, with plenty of easy stops and short drives between scenic spots.
2. Backroads to the Desert: Borrego Springs Loop
Route: Julian → Anza-Borrego Desert State Park → Borrego Springs → Montezuma Grade → Warner Springs
While the desert may seem vast and empty, Anza-Borrego is bursting with life and artistry. This loop takes you through surreal desert landscapes dotted with giant metal sculptures—everything from prehistoric creatures to mythical beasts—crafted by artist Ricardo Breceda.
Pull over for a night under a star-filled sky at Palm Canyon Campground or find a peaceful boondocking spot off Di Giorgio Road. A self-contained camper from a California camper van rental company makes this route easy—off-grid power, cozy sleeping quarters, and a fridge full of cold drinks make all the difference when desert temperatures swing from blazing to brisk.
3. The Forgotten Coast: Point Loma to Baja’s Wine Country
Route: San Diego → Rosarito → Ensenada → Valle de Guadalupe
While many travelers cross the border for tacos and surf, few continue inland to Valle de Guadalupe, Mexico’s thriving wine region just 90 minutes south of San Diego. The drive is smooth, the people are welcoming, and the scenery—rolling hills lined with vineyards and olive trees—is downright Tuscan.
This route is tailor-made for van life. Stay at boutique vineyard camp spots like El Cielo or Vena Cava, where you can sip local reds by the fire. Make sure your rental allows international travel—many San Diego camper van rental companies offer special insurance for Baja trips.
4. The Mojave Secret: Route Through Joshua Tree and Beyond
Route: San Diego → Joshua Tree → Amboy Crater → Mojave National Preserve
For those craving solitude, head northeast into the heart of California’s high desert. The drive from Joshua Tree to Mojave is filled with alien landscapes, volcanic craters, and vintage Americana straight out of a road trip dream.
Camp among the boulders in Joshua Tree National Park, then follow old Route 66 through Amboy—home to the iconic Roy’s Motel & Café. The Mojave Preserve’s dispersed camping areas are a paradise for van lifers: endless stars, quiet nights, and a feeling of being completely untethered.
Families will love this route too—space to roam, safe campsites, and natural wonders at every turn. A family van rental gives you everything you need: sleeping space, cooking gear, and the ability to chase the horizon without a single hotel check-in.
5. Sierra Secrets: Highway 395 Adventure
Route: San Diego → Lone Pine → Bishop → Mammoth Lakes → Convict Lake
This route may be the most breathtaking road trip in all of California, yet it’s surprisingly under-the-radar compared to coastal drives. Highway 395 runs along the eastern edge of the Sierra Nevada, where desert meets alpine peaks.
Stop at the otherworldly Trona Pinnacles, wander through the Alabama Hills, soak in the Wild Willy’s Hot Springs, and hike to Big Pine Lakes—turquoise waters framed by rugged granite mountains.
This trip is best enjoyed in a well-equipped California camper van rental built for off-grid adventure. The route’s mix of high desert and mountain climates means flexibility is key—having your kitchen, bed, and bathroom on wheels keeps you comfortable no matter what nature throws your way.
Ready to Roll
Whether you’re looking to escape for a weekend or a week, these hidden gems prove that California’s best road trips aren’t always the most famous ones. From desert art parks to alpine lakes, quiet vineyards to volcanic craters, there’s a whole world waiting just beyond San Diego’s city limits.
Before you hit the road, make sure your ride is as ready as you are. A San Diego camper van rental gives you the freedom to explore at your own pace, while a family van rental makes it easy to share the journey with those who matter most. So pack your camera, grab your map, and set your sights on the roads less traveled—your next great adventure is only a turn of the key away.
