Great Sand Dunes Backcountry pro tips

  1. Your parking lot is assigned from your first night's location. Request a different one 7 or more days ahead if you need it, and know it is not guaranteed.
  2. Once your parking request is granted, the permit locks. No changes after that.
  3. Sand stakes or rocks. Regular tent stakes pull straight out of dune sand.
  4. Sand Creek is the only place in the backcountry with a legal fire ring, and its bear box is mandatory.

About this permit

Great Sand Dunes issues one backcountry permit that covers two very different trips. Dunes Backcountry is non-designated camping anywhere in the 30 square mile dunefield west of the high ridge and beyond the day use area, capped at 20 permits per day for groups of no more than six. Sand Ramp Trail camping is at seven designated sites, each holding six people, marked by a metal arrowhead post you must camp within 50 feet of.

Permits are available year round on a rolling three month window, released at 7:00 am Pacific each day. There are no first-come first-served permits at the park, though same-day reservations are possible if quota remains.

The route

The dunefield trip is short and brutal. Walk past the day use area, climb the first high ridge, and keep going until you see no structures and no roads. The Park Service asks for a minimum of one hour of climbing to reach the top of the first ridge and at least 1.5 miles west of the Medano Creek bed. Set up in a low flat area away from vegetation.

The Sand Ramp Trail is the other half of this permit and it is a normal trail. Buck Creek sits 1.0 mile from the Amphitheater lot. From the Horse Parking Lot it is 2.8 miles to Escape Dunes, 4.1 to Indian Grove, 5.0 to Little Medano, 7.0 to Aspen, 10.1 to Cold Creek and 11.6 to Sand Creek. Aspen sits at 9,240 feet, the highest designated backcountry site in the park.

Your parking lot is assigned from where you sleep the first night, which is unusual and worth knowing before you book.

Why it matters

There is almost nowhere else in the country where a park lets you sleep in open sand with no designated site, no fire ring and no neighbor. The park caps the dunefield at 20 permits a day and asks only that you get past the first ridgeline, which is the difference between a novelty and real solitude.

The feeling

Climbing dunes with a full pack is the most tiring easy mile you will ever walk. Then you crest the ridge and everything man-made disappears at once. The wind erases your tracks by morning, the sand holds the day's heat, and the sky at 8,000 feet is thick with stars.

Great Sand Dunes Backcountry photography guide

Golden Hour

First and last light rake the dune ridgelines into hard edges. Twenty minutes either side of the sun touching the Sangre de Cristos is the window.

Best Light

Midday flattens the dunes completely. Shoot early, shoot late, or shoot the night sky.

Beat the Crowds

Everyone stops at the first ridge for the view and turns around. Walk twenty more minutes west and you have the dunefield to yourself.

Classic Shots

  1. Dune ridgelines at sunrise with the Sangre de Cristos behind
  2. A single tent on open sand with no tracks around it
  3. Star trails over the dunefield
  4. Medano Creek braiding across the sand flats in late spring

Great Sand Dunes Backcountry rules, gear and safety

Gear checklist

Required
  • A gallon of water per person per night, since sources are seasonal
  • Sand stakes or rocks. Standard stakes do not hold in dune sand
  • A free-standing tent for the dunefield
  • Gas stove, because campfires are prohibited everywhere except the Sand Creek fire ring
  • Bear canister or a Kevlar hang bag with rope

Recommended gear

  • Gaiters, which keep about half the dunefield out of your boots
  • Sunglasses and a buff for blowing sand
  • Warm bag. Nights at 8,000 feet and up get cold in every season
  • Trekking poles for the ridge climb with a full pack

Hazards & considerations

  • Sand surface temperatures that can exceed 150F on summer afternoons
  • Lightning on the exposed dunefield, which has no shelter of any kind
  • Disorientation after dark, because dunes look identical and your tracks blow away
  • Seasonal water sources that may be dry when you arrive
  • Cold nights and wind at 8,000 to 9,240 feet
