Enter The Slot at First Light
The day starts on the road in the dark, so that you can walk into The Slot as the sun comes up. The Slot is a narrow, winding sandstone canyon cut into the badlands off Buttes Pass Road, reached from Highway 78, and it's the first stop on this Anza-Borrego itinerary because it's one of the most distinctive pieces of geology in the park, and it fits neatly into the coolest hours of the day.
The walk itself is modest: about 2 miles round trip, with roughly 100 feet of elevation change, rated easy to moderate. The trail descends into the canyon, and then the sandstone walls begin to close in. At points the passage gets tight enough that you'll want to slow down and watch your footing, and the route twists and turns like a maze. The Anza-Borrego Foundation calls it one of the most popular hikes in the park, and the formations are why.
Going early does two jobs. It puts you in the canyon during the coolest part of a desert day, and it leaves the rest of the day open for Palm Canyon and town. It also means you'll be here before the Visitor Center opens, so do the ranger's homework yourself before you leave San Diego: read the park's road conditions page and check the forecast.
The approach is dirt. The park's road table, last updated February 5, 2026, rates Buttes Pass Road to The Slot as fine for two-wheel drive and in good condition, with sand and washboard. Treat that as a starting point, since conditions can change after any storm. Rain is the one firm rule. Slot canyons flash-flood, so if rain is anywhere in the forecast, save The Slot for another trip and begin at the Visitor Center.
Two last things to handle at home. Bring $10 for the day-use fee, which is now collected per car at The Slot, and download your navigation before you leave, because cell service out here comes and goes.
