Mortero Canyon Loop

This 13.5-mile loop in Anza-Borrego Desert State Park takes you through stunning desert terrain, showcasing rugged washes, historic sites, and expansive views. The route follows Mortero Wash south before making a clockwise loop through Upper Jojoba Wash, Goat Canyon Trail, Jojoba Wash, West Dolomite Mine Road, and Dolomite Mine Road. Expect a mix of sandy washes, rocky terrain, and rolling hills, with opportunities to explore abandoned mining sites and unique desert geology.

The hike begins at Mortero Wash, a wide, sandy path that gradually narrows as it winds through classic Sonoran Desert landscapes. As you move south, you’ll pass scattered ocotillos, cholla, and barrel cacti, and if you're lucky, you might spot the occasional desert bighorn sheep on the ridges above.

At the junction with Upper Jojoba Wash, the terrain becomes more rugged, with sections of loose rock and dry waterfalls. Continuing onto Goat Canyon Trail, you'll have views of the famous Goat Canyon Trestle, one of the largest wooden railway trestles in the world, though reaching the trestle itself requires an off-route detour.

Turning onto Jojoba Wash, the route gradually flattens out, offering a mix of soft sand and rocky sections. The trail eventually connects to West Dolomite Mine Road, leading past remnants of historical mining activity, including rusted equipment and abandoned shafts. The final stretch along Dolomite Mine Road offers expansive views of the surrounding desert before looping back to Mortero Wash.

Flora & Fauna

The route is lined with ocotillo, jojoba, creosote, and cholla cactus. In spring, wildflowers like desert lilies and sand verbena may be in bloom. Wildlife includes desert bighorn sheep, jackrabbits, and the occasional coyote. Watch for rattlesnakes in warmer months.
