I used to live in the closet town to the Sand Dunes. They are amazing and don’t be surprised if you come upon horses with webbed feet because there has been reportings of mutated animals living within the dunes. :]

It’s amazing and everyone should have that experience. But be prepared to have sand in your hair and under your nails for a couple weeks. It’s also best to be wearing some type of sandal [the sand is easier to get out.]

One other thing, don’t go when it’s windy [the San Luis Valley is notorious of being windy] unless you want bruises and maybe even a little cut or two on those windy days.
