Two hours from San Diego, this California desert hides jade oases and giant metal monsters

It’s two hours from San Diego

Anza-Borrego Desert State Park sprawls across more than 600,000 acres of Southern California’s Colorado Desert, and it feels like you dropped onto another planet.

The Peninsular Ranges block Pacific storms to the west, leaving everything east of them bone-dry. Badlands twist into slot canyons.

Palm oases hide in narrow gorges. Giant metal sculptures rise from the sand.

You can get here in about two hours from San Diego, Riverside, or Palm Springs, and the tiny community of Borrego Springs sits right in the middle of it all, completely surrounded by park land. The desert looks empty from the road.

It isn’t.

Seven million years of fossils under your feet

The park got its start in 1932, when California first set aside parcels of this desert for protection.

Its name comes from Spanish explorer Juan Bautista de Anza, who crossed here in 1774, and “borrego,” the Spanish word for bighorn sheep.

Millions of years ago, a tropical inland sea connected to the Gulf of California covered this ground. That sea left behind one of North America’s most continuous fossil records, spanning roughly seven million years.

More than 550 types of fossil plants and animals have turned up here, including mammoths, giant ground sloths, and saber-toothed cats.

The Kumeyaay people lived in these canyons for thousands of years, and you can still find their petroglyphs, pictographs, and grinding rocks along the trails.

Wildflowers carpet the desert floor in spring

When winter rain falls at the right time and in the right amount, Anza-Borrego puts on one of the biggest wildflower shows in the country.

The bloom usually runs from late February through early April, with mid-March as the sweet spot.

Purple desert sand verbena, yellow desert sunflower, white dune evening primrose, and golden poppies spread across the valleys. Henderson Canyon Road and DiGiorgio Road draw the biggest crowds.

After the annuals fade, cactus blooms take over, with beavertail, cholla, hedgehog, and barrel cactus flowering into April.

A true superbloom needs steady rain, mild temperatures, and no sudden heat spikes, so it doesn’t happen every year.

Hike a sandy wash to a fan palm oasis

Borrego Palm Canyon is the park’s most popular trail, about three miles round trip with roughly 450 feet of elevation gain.

You follow a sandy wash past barrel cacti, ocotillo, and desert lavender into a narrowing canyon. At the end, California fan palms crowd together around underground springs that feed a stream through the rock.

These are the only palm species native to California, and the green against all that brown desert hits you hard.

Dozens of migratory bird species stop at this water, and if you look up along the high canyon ridges, you might catch a glimpse of endangered peninsular bighorn sheep.

A 350-foot serpent rises out of the sand

About 130 giant metal sculptures stand scattered across the desert near Borrego Springs at Galleta Meadows. Local landowner Dennis Avery commissioned them starting in 2008, and artist Ricardo Breceda built every one.

Breceda, a self-taught welder from Durango, Mexico, got into sculpting after trading a pair of cowboy boots for a welding machine.

Many of the pieces depict prehistoric creatures whose fossils turned up in the park: mammoths, saber-toothed cats, ancient camels.

The showstopper is a 350-foot-long serpent that arcs out of the ground and dips under a road. You can drive a roughly 22-mile loop to see them all, and the Under the Sun Foundation stewards the collection.

It’s free.

Font’s Point drops you into a 20-mile maze of badlands

Font’s Point gives you one of the best views in the entire park, and Father Pedro Font, chaplain on Anza’s 1775 expedition, called the badlands below the “sweepings of the world.” He wasn’t wrong.

The Borrego Badlands stretch roughly 20 miles wide by 15 miles long, a tangle of eroded ridges, sunken mesas, and sandy arroyos.

Colored rock layers show millions of years of change, from underwater seabed to dry savanna. Get there at sunrise or sunset, when low-angle light cuts deep shadows across every fold.

On clear days, you can see all the way to the Salton Sea to the east and the Santa Rosa Mountains to the north.

Turn sideways to squeeze through The Slot

The Slot is exactly what it sounds like. Water carved a narrow passageway through the eroded badlands below Borrego Mountain, and in places, the sandstone walls close in tight enough that you have to turn sideways to fit through.

Look up and you’ll spot a natural rock arch wedged between the walls overhead.

The trail connects to a longer loop that takes you up to West Butte, where the desert opens up in every direction. You don’t need special gear beyond sturdy shoes and plenty of water, but stay away during or after rain.

Flash floods funnel straight through here.

Walk through wind-carved tunnels on Fish Creek Mountain

The Wind Caves sit on Fish Creek Mountain in the park’s eastern section. The hike is short, about 1.25 miles round trip with roughly 250 feet of elevation gain.

At the top, you find sandstone full of alcoves, tunnels, and overhangs large enough to walk through, all carved by wind over thousands of years. The pocketed rock looks like something you’d see on Mars.

Below you, the Carrizo Badlands spread across the desert floor.

This whole region once sat under an ancient sea, and fossils from that era still surface throughout the surrounding badlands.

Bighorn sheep and roadrunners share the desert

The park takes its name from the endangered peninsular bighorn sheep, and they’re still here. You might spot them on rocky ridges above the canyons, especially near water sources in the cooler months.

Greater roadrunners, golden eagles, kit foxes, mule deer, coyotes, and black-tailed jackrabbits all call this desert home. Reptiles include desert iguanas, chuckwallas, and the red diamond rattlesnake.

The palm oases and springs pull in migratory birds, so birdwatchers do well here. Desert iguanas and chuckwallas come out more in warmer months, while cooler weather brings the mammals into view.

The Milky Way shows up with the naked eye

Borrego Springs became California’s first International Dark Sky Community in 2009, and the park itself earned International Dark Sky Park status in 2018.

Nearly a thousand square miles of undeveloped desert surround the community, and mountains on three sides block light pollution from San Diego, Los Angeles, and Palm Springs.

On a clear night, you can see the Milky Way without binoculars or a telescope. Millions of people live along the Southern California coast and never get that view.

Out here, you just look up.

Five more trails worth lacing up your boots for

The Narrows Earth Trail is an easy half-mile walk off Highway 78 that takes you through a small canyon where you can read the geology in the walls.

The Yaqui Well Nature Trail runs 1.5 miles one way from Tamarisk Grove Campground through a historic watering spot lined with desert ironwood trees.

The Pacific Crest Trail passes through the western part of the park, giving you roughly 50 miles of desert hiking. A segment of the Juan Bautista de Anza National Historic Trail cuts through the northern section.

Near the visitor center, the Cactus Loop trail gives you a quick, easy walk through native desert plants.

The visitor center is built underground

Park staff built the visitor center underground in 1979, and the desert heat is the reason. You won’t even see the building as you walk up to it.

A rooftop desert garden of native plants covers the top, and a short trail from the parking lot leads you to the roof, where Borrego Valley opens up in every direction.

Inside, exhibits cover the park’s paleontology, archaeology, geology, and wildlife, including a mammoth skull.

Rangers and volunteers hand out maps, trail updates, and road condition reports daily during the October through May season.

Explore Anza-Borrego Desert State Park in California

You can reach Anza-Borrego about two hours east of San Diego. The park has no entrance gate, so you drive in freely on paved highways S22, S2, and Route 78.

The visitor center sits at 200 Palm Canyon Drive in Borrego Springs, open daily October through May and weekends June through September.

Dispersed backcountry camping is free across the park’s 600,000-plus acres, with vehicles parked no more than one car length off any road. Four developed campgrounds and eight primitive sites give you more options.

Font’s Point and Wind Caves require high-clearance or 4WD vehicles. No drones, off-highway vehicles, or firearms allowed.

Summer tops 100 degrees, so October through April is your best window.
