Visiting Great Sand Dunes National Park: A Complete Guide
Visiting Great Sand Dunes National Park: A Complete Guide was originally published in 2025
I remember the first time we rolled into Great Sand Dunes National Park in Southern Colorado, my car coated in a thin layer of desert dust, playlist humming something half-forgotten, as the dunes rose like a mirage from the high alpine basin.
You’ll think you’re hallucinating when you see these dunes, North America’s tallest, some cresting at over 750 feet, backed by the jagged Sangre de Cristo Mountains, with clouds throwing long shadows across the rippled sand.
We visited as a stop on a longer Southern Colorado and Northern New Mexico road trip, en route to Mesa Verde National Park and later, the Bisti Badlands. In this guide, learn everything you need to know in order to plan a picture-perfect visit to Great Sand Dunes National Park.

Shifting Sands, Shifting Perspectives
These dunes formed over thousands of years as winds funneled through mountain passes, dropping sand at the foot of the Sangre de Cristos. Indigenous peoples like the Ute and Apache have called this valley home for centuries, weaving stories of the dunes into their cosmologies. Even today, the dunes hum with a strange energy, especially when the wind picks up and the sand begins to sing beneath your feet.
