The High Dune isn't the highest peak of the Great Sand Dunes, but the view is breathtaking. The effort to tackle the sometimes steep sections is worth it. Plenty of water is recommended, as it can get very hot and windy.

Hiking up the dune is a wonderful experience, but you should be in good shape. It can be strenuous to climb the inclines in the loose sand. The view from the dune is magnificent; you can see in every direction.

The Great Sand Dunes cover an area of approximately 80 km² and, at a height of approximately 230 meters, are the highest dunes in North America. The sand dunes are approximately 12,000 years old and were formed by sand deposits from the Rio Grande and its tributaries. You should be in good physical shape to hike the dunes. The constant inclines in the loose sand can be very strenuous.

Unfortunately dried out in summer. But you can see the riverbed from the greenery that is still there.

With a height of 688 feet (at an elevation of 8,727 feet), High Dune is – along with Star Dune just next to it – one of the tallest sand dunes in North America. There are no trails leading up to the summit, but you can ascent the dune from the Dunes Parking by hiking crosscountry. The view from this majestic dune that is nestled at the foot of the Sangre de Christo Mountains is unique. Bring plenty of water and avoid the heat of the day and stormy weather.
