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 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.
