Truckhaven to The Slot

This 37.3-mile loop connects two of the most iconic features in Ocotillo Wells: the rugged Truckhaven Trail in the north and the famously narrow Slot Canyon to the south. Starting from the Truckhaven Trailhead off S22 near Calcite Mine, this route dives into the sandy expanse of Arroyo Salado before winding through a network of trails and washes that define the badlands.

You'll follow the Truckhaven Trail south to Arroyo Salado, where wide-open desert gives way to sculpted canyon walls. From there, Cut Across Trail and San Felipe Wash guide you toward The Slot, a twisting, photogenic canyon that's a highlight of Anza-Borrego. It’s tight, it’s dramatic, and yes—everyone crawls a little.

Heading back, the route loops north via Palo Verde Wash, with a quick stop by Arroyo Salado Campground before reconnecting with the Truckhaven Trail for the final stretch.

Expect soft sand, ever-changing terrain, and minimal shade—this one’s best done in cooler months. The area is riddled with intersecting dirt roads, dry washes, and unnamed canyons, making the route highly customizable for those looking to do some off-trail exploring or shorten the mileage.

Flora & Fauna:
You’ll see plenty of creosote bush, ocotillo, and desert lavender. In spring, keep an eye out for wildflowers like desert sunflower and sand verbena. Wildlife can include jackrabbits, desert iguanas, side-blotched lizards, and if you’re lucky (or unlucky, depending), a rattlesnake sunning in the wash.
Parking: Free parking is available at the Calcite Mine / Truckhaven Trailhead. No permit required, but it’s worth checking with Ocotillo Wells SVRA for updates on conditions and vehicle access.

Recommended For: Experienced hikers, backpackers, and off-roaders looking for an adventure through the desert.

Camping: Arroyo Salado Primitive Campground offers dispersed sites with no amenities. 

SAFETY AND CONSIDERATIONS
Carry plenty of water—there is zero reliable water along this route—and download offline maps. Cell service is spotty at best, and many trails are unmarked or change due to flash flooding.

Permits: No permits are required for hiking. If exploring within Anza-Borrego Desert State Park boundaries, check for any restrictions or permits needed for specific activities.
