Anza Borrego Desert State Park is home to many slot canyons. A favorite that is a simple drive (especially for 2wd cars) is just off of Route 78. Leaving the town of Borrego, take Borrego Springs Road south east through Texas Dip. At the junction of 78 turn left and drive apx 1.5 miles until you see a small sign for Buttes Pass. Turn left and drive the dirt road for less than two miles to the main parking area (stay left along the way unless you also want to visit Hawks Canyon). The trailhead is unmarked but follow the path from the parking lot and you will soon find yourself on the .8 mile trail through the slot canyon.
