What to Expect

This trail drops you into another planet. From the trailhead, you immediately leave behind any sense of civilization and wade into a sea of brilliant white gypsum dunes that roll in every direction like frozen waves. The loop route takes you up and over dune after dune — none of them massive, but the relentless up-and-down through soft sand will have your calves burning within the first mile. Navigation relies entirely on orange trail markers planted in the sand, and between markers the landscape is so featureless it borders on disorienting. You'll reach the edge of Alkali Flat, a cracked, bone-dry lakebed that once held water thousands of years ago — the contrast between blinding white dunes and this stark, flat expanse is genuinely surreal. On the return loop, you'll likely have the dunes entirely to yourself. This trail rewards hikers who want to feel genuinely alone in a landscape that looks nothing like anywhere else on Earth.

Safety Advisory

There is zero shade on this entire trail. Ground temperatures on the white sand can exceed air temperature significantly, and heat exhaustion is a real risk from late spring through early fall. Carry at least two liters of water per person — three in summer — and turn back if you feel dizzy or stop sweating.

The trail markers are the only navigation aid out here. If a marker is knocked down or obscured, the featureless dune field becomes genuinely disorienting. Carry a charged phone with downloaded maps, and note the GPS coordinates of the trailhead before you start.

The park closes the dune drive gates at sunset and will lock you in. Check gate closing times at the visitor center before heading out — if you start this trail late, you may not finish before lockout.

Pro Tips

Trail Tip

Start within an hour of the park opening — afternoon heat turns this into a survival exercise, and the low-angle morning light makes the dunes glow in ways that midday sun completely flattens.

Trail Tip

Wear gaiters or tall socks over your shoes. The fine gypsum sand infiltrates everything, and you'll be stopping every ten minutes to dump your shoes otherwise. Trail runners work better than heavy boots here since the terrain is all sand, no rock.

Trail Tip

The orange trail markers can be hard to spot when you're in a dune trough — before descending any dune, stop at the crest and visually locate the next two markers ahead. People get turned around here more often than the park likes to admit.
