Vallecito Loop

Vallecito Loop is a 25.3-mile route in Anza-Borrego Desert State Park that takes you through rugged desert landscapes, winding canyons, and fascinating geological features. Starting on Vallecito Creek Road, the route loops through Arroyo Seco del Diablo, the Tapiado-Diablo Cut Across, and Arroyo Tapiado, passing the park’s famous mud caves before reconnecting with Vallecito Creek Road. This remote and challenging route offers solitude, dramatic scenery, and a fun desert adventure for experienced hikers or backpackers.

DESCRIPTION

Begin at Vallecito Creek Road, a sandy desert track accessible off Highway S2. Follow the road as it winds through open desert terrain, offering views of scattered creosote bushes and distant desert ridges.

After several miles turn onto Arroyo Seco del Diablo. This section includes sandy washes and occasional boulder scrambles, with unique rock formations adding to the dramatic scenery. From Arroyo Seco del Diablo, transition onto the Tapiado-Diablo Cut Across, a rugged connector trail that offers expansive views of the surrounding badlands. The terrain here is varied, with sections of rocky paths and sandy washes.

Once on Arroyo Tapiado, you’ll pass the park’s famous mud caves. These natural formations are a highlight of the route and offer opportunities for exploration. Exercise caution when entering the caves, as some may be unstable.

Continue along Arroyo Tapiado, following the winding canyon until it reconnects with Vallecito Creek Road. Retrace your initial route back to the starting point to complete the loop.

FLORA AND FAUNA

The route features classic desert vegetation, including creosote, ocotillo, cholla, and barrel cacti. Spring wildflowers, such as desert lilies and sand verbena, may bloom along the way. Wildlife sightings may include jackrabbits, lizards, roadrunners, and occasionally desert bighorn sheep or coyotes.

CAMPING: Dispersed camping is allowed along the route. Look for flat, open spaces away from washes to set up camp. Follow Leave No Trace principles.

PERMITS: No permits are required for hiking or camping, but check for any seasonal restrictions or park regulations.
