What to Expect

Forget everything you know about hiking trails — there is no trail here. You'll wade across Medano Creek (ankle- to knee-deep in late spring, bone-dry by August), then face nearly four miles of open sand with nothing but your own footprints and the wind-sculpted ridgelines ahead. The sand is relentless: two steps forward, one slide back, with each dune crest revealing another beyond it. Star Dune itself tops out around 750 feet above the valley floor, making it one of the tallest dunes in North America, and its distinctive multi-armed shape is best appreciated from the surrounding ridgelines. The summit panorama — Sangre de Cristo peaks behind you, the entire dunefield rippling below — is genuinely breathtaking. This one is for hikers who want to earn something extraordinary through sheer stubbornness.

Safety Advisory

Dehydration and heat exhaustion are serious risks from late spring through early fall. The sand reflects heat from below while the sun hammers from above, creating temperatures far hotter than the posted forecast. Turn back if you feel dizzy or stop sweating.

Lightning is a lethal threat on the open dunefield — you are the tallest object for miles. Check the forecast obsessively and plan to be off the dunes by noon during monsoon season (July through September). If a storm rolls in, descend immediately and stay low.

Pro Tips

Trail Tip

Start at first light — the sand temperature can exceed 150 degrees by midday in summer, and morning shadows create dramatic dune textures. You'll also benefit from firmer, cooler sand that hasn't been baked loose yet.

Trail Tip

Bring at least three liters of water per person and wear gaiters or tall socks over your shoes. Sand in your boots turns a tough hike into a miserable one. Trekking poles help enormously on the steep dune faces where footing is unreliable.

Trail Tip

Navigate by aiming for the tallest formation on the horizon rather than following any specific route — there are no markers. Use the Sangre de Cristos as your compass on the return. The northwest ridge of Star Dune offers the firmest footing and the best views for photos.
