🌲 Park Overview

Nestled against Colorado’s snow‑capped Sangre de Cristo Mountains, Great Sand Dunes National Park & Preserve boasts the tallest dunes in North America—some soaring over 750 feet. This surreal sandbox covers just 30 square miles, yet sits within a vast 150,000‑acre wilderness of alpine tundra, aspen forests, and sparkling high‑country lakes. From sand‑sledding to mountaintop treks and nighttime stargazing in a certified Dark Sky Park, Great Sand Dunes delivers high‑contrast adventure for every type of traveler.

🌟 Fun Facts

The dunes were formed by 13,000 years of wind funneling sand from the San Luis Valley against the mountains.

Star Dune is the park’s tallest at ~755 ft—and it’s still growing.

Medano Creek’s seasonal “surge flow” creates a wave‑like beach every late spring.

Designated an International Dark Sky Park in 2019—Bortle 1–2 skies.
