Park Features

The Sand Dunes

The sand dunes, which can reach heights of up to 750 feet, are the heart of the park. They are home to a range of wildlife species, many of which are unique to this type of ecosystem.

Description of the Dunes

The sand dunes are undoubtedly the most prominent feature of the park. They rise up to 750 feet in height and cover an area of about 30 square miles. They are composed of sand grains that have been carried by the wind over thousands of years.

The Sangre de Cristo Peaks

To the east of the dunes, the Sangre de Cristo Peaks provide a dramatic contrast with their mountainous and forested landscape, rich in wildlife.

Description of the Peaks

The Sangre de Cristo Peaks, bordering the park to the east, offer a striking juxtaposition with the sand dunes. These mighty mountains, some exceeding 14,000 feet in elevation, are covered in coniferous forests and harbor a diverse array of wildlife.

Wildlife Species in the Peaks

The Sangre de Cristo Peaks are home to a rich variety of wildlife, including elk, mule deer, mountain lions, and various bird species. At higher elevations, one can find marmots and bighorn sheep.

Medano Creek and its "Sand Surfs" Phenomenon

Medano Creek flows along the eastern edge of the dune field and is famous for its "sand surfs" phenomenon, a rare natural occurrence that turns the creek into a miniature beach during the spring and early summer.
