The two tiers of the waterfall aren't visible from the outside, but can only be heard. It's essential to walk along the edge or in the riverbed for a while. Depending on the water level, this may be possible without any slippery feet. The stones aren't particularly slippery. This river path should be avoided in winter.

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.

Definitely worth the hike. The waterfall is hidden between the rock walls, so water shoes are necessary.
