🥾 ActiveLong weekend · from San Diego, CA
Anza-Borrego, Salton Sea & Imperial Sand Dunes
Two hours east of San Diego, the Colorado Desert drops 3,000 feet from the Laguna Mountains into the Salton Trough — one of the lowest, hottest, and most geologically violent landscapes in North America. Anza-Borrego Desert State Park (the largest California state park, 600,000 acres) protects the western reaches of the Colorado Desert with slot canyons, elephant tree groves, and the most dramatic wildflower blooms in the American Southwest during wet years. The Salton Sea — a 45-mile-long accidental inland sea created by an irrigation canal break in 1905 — is the most haunted landscape in California: a receding saline lake ringed by the ruins of 1950s resort towns and traversed by millions of migratory shorebirds. The Imperial Sand Dunes at Glamis are the largest sand dune complex in the United States east of the Colorado River.

Borrego Palm Canyon Trail
★ 4.8The signature trail of Anza-Borrego — a 3-mile round trip from the campground to a fan palm oasis in a slot canyon cut by a seasonal stream. The trail passes through boulder-strewn desert terrain before entering the canyon, where 1,000 native California fan palms grow in a natural grove fed by a year-round spring. Bighorn sheep are commonly visible on the canyon walls; the canyon slot has 50-foot walls in the narrowest section above the palm grove.

The Slot — Anza-Borrego
★ 4.8A 0.75-mile slot canyon south of Borrego Springs with 30-foot conglomerate walls less than 3 feet apart — accessible on foot from a roadside pullout. The canyon follows a fault line through the Borrego badlands; the conglomerate walls are compressed river cobble cemented into the canyon walls over millions of years. A different geological medium than the sandstone slot canyons of Utah; the Anza-Borrego slot carves through the compressed delta deposits of the ancestral Colorado River.

Afternoon
Font's Point
★ 4.9The overlook above the Borrego Badlands — a 4-mile unpaved road through a sandy wash leads to Font's Point, where the Borrego Badlands extend for 30 miles in an eroded moonscape of clay and siltstone towers. The badlands formed from the Pliocene lake sediments deposited when the Salton Trough filled with Colorado River water; the fossilized marine shells, mastodons, and camels found here are now in the museum at the Anza-Borrego visitor center. Sunset at Font's Point is the most dramatic desert light show in Southern California.

Borrego Springs Resort & Spa
★ 4.3The principal resort in Borrego Springs — an International Dark Sky Community (no streetlights; the sky is among the darkest in California). The resort's pool and restaurant are the evening standard; the Carlee's restaurant on Christmas Circle is the local alternative. The Ricardo Breceda metal sculpture garden on the edge of town (55 life-size metal sculptures of prehistoric animals and a Chinese dragon) is visible from the road after dark.

Salton Sea State Recreation Area
★ 4.1The north shore of the Salton Sea — the California state park preserves the last functioning stretch of the Salton Sea shoreline, where migratory birds concentrate in enormous numbers (the Salton Sea is a critical stop on the Pacific Flyway). The lake surface is 236 feet below sea level and 50% saltier than the ocean; the tilapia introduced in the 1950s are the primary food source for the 400+ bird species documented here. The receding shoreline has exposed miles of white crystallized salt and bird bones.

Bombay Beach
The most surreal landscape in California — a partially abandoned 1950s resort community on the southeast shore of the Salton Sea, now partially below the water level of the receding lake. The inundated streets and the ruins of the old bungalows along the beach have been colonized by an artist community that holds an annual 'Bombay Beach Biennale' (outdoor installations across the ruins). The combination of decaying resort infrastructure, salt flats, and the looming sea makes this the most photographed landscape in the California desert.

Afternoon
Sonny Bono Salton Sea National Wildlife Refuge
★ 4.1The south end of the Salton Sea — the 37,600-acre wildlife refuge at the south shore is the primary birding site at the Salton Sea, with seasonal shorebird concentrations of 50,000+ birds (dunlin, western sandpiper, eared grebe) and the year-round pelican and great blue heron colonies. Named for Sonny Bono, the Palm Springs congressman who led the effort to restore the Salton Sea before his death in 1998.

Imperial Sand Dunes Recreation Area
★ 4.8The Sahara of California — 40 miles of sand dunes 2 miles wide along the old Algodones Dune field, the largest sand dune complex in the United States. The dunes reach 300 feet tall; the sand has been blowing east off the former Lake Cahuilla delta for 10,000 years. The Glamis section is heavily used by OHV riders on weekends (the dune buggy culture here is the largest OHV gathering in North America); the Dune Buggy Flats area has rentable dune buggies and is the most accessible section for first-time visitors. Morning is the best time: cool temperatures, OHV traffic is lighter, and the dune shapes are sharpest.
