Great Sand Dunes National Park and Preserve Alerts and Current Conditions

Cover of Brian Russ's guide to Great Sand Dunes National Park and Preserve

Last checked: October 25, 2026. This page tracks what's closed, what's changed, and what's coming up at Great Sand Dunes National Park and Preserve, Colorado, from the park's alerts, conditions, and hours pages. I check it daily and rewrite it when the park posts something new, so bookmark it rather than an old news story. At 8,200 feet, one storm can turn a quiet creek crossing into a deep one overnight, so check the park's own alerts the morning you go.

Current alerts

  • Deep, swift water at the Medano Pass Primitive Road crossings. The park's weather station measured 1.5 inches of rain overnight on October 23, and Medano Creek was running at 28 cubic feet per second. Several of the nine creek crossings on this 4WD-only road have fast water 3 feet deep or more. The park advises extreme caution. This doesn't affect the Main Dunes Parking area, Piñon Flats Campground, or the visitor center. (NPS)
  • Stage 1 fire restrictions have been in effect since August 18. Wood and charcoal fires are allowed only in established fire rings at designated campsites or picnic sites, and must be put out cold and never left unattended. Camp stoves and other pressurized gas devices are allowed. (NPS)
  • Slow down inside the park. Speed limits drop to 30 mph near the park boundary and as low as 10 mph near headquarters and the entrance station. (NPS)
  • No sandboard or sand sled rentals in the park. Rentals are in the surrounding communities, so arrange one before you arrive. (NPS)

Open and closed right now

  • The park and preserve are open 24 hours a day, all year. Entrance is $25 per private vehicle. Fees are charged when the entrance station is open (spring through fall) or, in winter, when the visitor center is open. You can pay by cash, check, or card, or buy a pass ahead on Recreation.gov. (NPS)
  • Entrance station: open intermittently outside the May-to-September busy season. Call the fee manager at 719-378-6352 for that day's hours.
  • Visitor center: open daily, 9 a.m. to 4:30 p.m. Its bookstore sells some snacks, and that's the only food in the national park. (NPS)
  • Piñon Flats Campground: open through October, reservation only on Recreation.gov (1-877-444-6777). Sites can be booked three months in advance. (NPS)
  • Medano Pass Primitive Road campsites: first-come, first-served. The road is high-clearance 4WD only and open from late spring through fall as conditions permit.
  • Backpacking: available year-round with a permit from Recreation.gov. (NPS)
  • Medano Creek: the park's conditions page (updated October 22) says the 2026 water year was one of the driest on record and the creek won't flow by the main dunes parking lot.

Coming up in the next few weeks

  • Sunday, November 1: Piñon Flats Campground closes for the season and stays closed through March 31, 2027. The park says car camping isn't permitted anywhere in the park or preserve during those winter months.
  • Also from November 1: the entrance station is listed as closed through February 28, 2027. Fees are then charged when the visitor center is open.
  • Thanksgiving (Thursday, November 26): the visitor center is closed. It's also closed Christmas Day and New Year's Day.
  • Medano Pass Primitive Road: the park describes it as open late spring through fall as conditions permit, and it doesn't give a closing date.

What this means for your trip

The Medano Pass alert matters only if you're driving that 4WD road. For the classic visit (the visitor center, the main dunes parking area, and a climb onto the sand), the park says the storm doesn't change anything. If the road was in your plan this week, water three feet deep and moving fast at several crossings is a good reason to turn around, even in a capable vehicle.

Campers have one week left. Piñon Flats closes November 1, and after that there's no car camping inside the park or preserve. The park says a few campgrounds in the area stay open year-round. Backpacking in the dunes or forest is still allowed with a permit, but the park warns you to be ready for snow and frigid nights.

Late fall here means chilly nights and cool to warm, often windy days. Dress in layers, bring goggles for the wind, and pack your own lunch and plenty of water. The air is very dry at this elevation, and the park suggests taking it easy at first if you've come up from lower country. And don't count on a creek at the base of the dunes. The park's conditions page, updated the day before the October 23 storm, said Medano Creek wouldn't reach the main parking area this year, so ask at the visitor center if that's what you're hoping for.

If a closure knocks out part of your plan, my guide to Great Sand Dunes National Park and Preserve has nine one- to three-day itineraries at easy, moderate, and strenuous effort, each with a backup plan for weather or closures. You can also check alerts and conditions for every national park.
