It’s one of the most surreal landscapes in Colorado — a sea of sand at 8,000 feet backed by 13,000-foot peaks. Here’s how to make the most of it.
What to do
- Sandboard or sled the dunes — rent a board in Alamosa or at the park entrance; the sand is too soft for regular sleds.
- Splash in Medano Creek — a wide, shallow seasonal creek at the base of the dunes, peaking late May to June.
- Hike to High Dune for the classic view (there’s no trail — you just climb the sand).
- Stargaze — the park is an International Dark Sky Park with phenomenal night skies.
When to go
Late spring (May–June) is prime for Medano Creek and cooler sand. In summer, the sand surface can hit 150°F by midday — hike the dunes early or near sunset. Fall is quiet and beautiful; winter brings snow-dusted dunes.
Getting there & where to stay
The park sits in the San Luis Valley, about 35 minutes from Alamosa and roughly four hours from Denver. Alamosa has the closest hotels and services.
