Best Offroad Trails to Explore this Summer
Whether you’re traveling in a dialed-in Sprinter van or a rugged Grenadier, summer is prime time to get off the pavement and into the wild. These three standout destinations across Baja, California, and Colorado offer scenic backcountry routes, challenging trails, and unforgettable views. Just make sure your rig is up to the task—some of these trails demand more than just clearance.
1. Cabo Pulmo, Baja California Sur
Great for: Sprinter Vans & Ineos Grenadiers
Terrain: Sandy tracks, rocky sections, remote desert roads
Skill level: Moderate
Best time to go: May–July
The journey to Cabo Pulmo on Baja’s East Cape isn’t just about the destination—it’s a full-on overland experience. Remote beach roads, desert tracks, and long washboard sections make this ideal terrain for both high-clearance Sprinter vans and more rugged 4x4s like the Grenadier.
This area is still off the radar for most tourists, and the blend of coastal desert and marine life is unlike anywhere else. You’ll be navigating long stretches of unpaved road with little support infrastructure, so make sure you’re well-prepared.
Why go:
- Camp along the Sea of Cortez
- Snorkel or dive the Cabo Pulmo Reef
- Beachside camping near Los Frailes
2. Eastern Sierra & Highway 395, California
Great for: Sprinter Vans & Ineos Grenadiers
Terrain: Alpine forest roads, high desert, rocky climbs (optional)
Skill level: Easy to moderate
Best time to go: Late May–October
If you’re building your summer trip around variety, it’s hard to beat the Highway 395 corridor. This route is ideal for Sprinter-based builds—tons of dispersed camping, natural hot springs, and accessible forest service roads. For those in Grenadiers or other serious 4WD rigs, optional offshoots like Coyote Flat or Wheeler Ridge offer plenty of technical challenge.
Top trails & stops:
- Coyote Flat (4WD only): Elevation over 10,000 feet, panoramic views
- Buttermilk Country (easy-moderate): Great for vans & climbers
- Hot Creek Geological Site: Soak nearby in Wild Willy’s or Hilltop Hot Springs
3. Colorado Rockies: Black Bear Pass, Imogene Pass & Hesperus
Best for: Ineos Grenadier or similar high-clearance 4x4s only
Terrain: Steep shale, high-altitude passes, switchbacks
Skill level: Advanced
Best time to go: July–early September
The San Juan Mountains are spectacular—but they’re not for everyone. These trails are not Sprinter-van-friendly due to tight switchbacks, steep drop-offs, and extreme elevation. This is pure Grenadier territory.
Black Bear Pass is infamous for its narrow, one-way descent into Telluride with no room for error. Imogene Pass, while slightly more forgiving, still demands real 4WD and careful driving. The Hesperus area near Durango offers a bit more breathing room, with forest roads and alpine lakes better suited for remote camping and exploring without the vertical drama.
Trail highlights:
- Black Bear Pass (12,840’): One-way thrill ride
- Imogene Pass (13,114’): Connects Ouray to Telluride with jaw-dropping views
- Hesperus Forest roads: Lesser-known, quieter camping options
Pro tip: Expect snow through late June. Always check pass conditions before heading out, and don’t run these trails solo.
Final Thoughts
From desert coastlines to towering alpine passes, these offroad routes offer something for every type of adventurer. Sprinter van travelers will love the accessible beauty of Baja and the Eastern Sierra, while Grenadier drivers can take it a step further in the San Juans.
