is in the Anza Borrego Desert just outside of the city of Anza Borrego.
This parking area mile 16.5 on Hwy. S-22 at the base of the Montezuma Grade. A bulletin board offers trail and nature information about Hellhole Canyon. This area has had several mountain-lion sightings and it is recommended that you not hike alone. This is a popular hiking area during the Spring and Fall. Summer temperature often exceed 100 degrees. Hike west up the alluvial fan.
Several hundred yards up the sandy trail is a trail south (left) up the ridge, which climbs about 3,000′ in six miles to Culp Valley. A trail to the north (right) leads across the alluvial fan to the visitor center parking lot. For Hellhole Canyon, continue following the trail west to the mouth of the canyon.
I was there, with a friend, in June and it was close to 100 degrees. Take lots and lots of water – more than you think you’ll need.
Camping is available in the state park.
