With dunes up to 750 feet tall extending for miles, Colorado's Great Sand Dunes National Park feels like an ocean of sand hills. The park’s geology and biology also make it a fascinating destination. Visitors will have access to a large diversity of habitats, including sand dunes, pines and aspens, and even spruce-fir forests and tundras.
Originally designated Great Sand Dunes National Monument, Great Sand Dunes National Park and Preserve was created by an act of the United States Congress on September 13, 2004.
The park now contains 107,000 acres.
When to Visit
The park is available year-round but spring and fall may be the ideal time to plan a trip due to moderate temperatures. The sand dunes can get extremely hot in the summer, and summer tends to be the most crowded time to visit.
