Great Sand Dunes National Park
Great Sand Dunes National Park is located in Southern Colorado - the park is open 24/7, year round. The day we visited the park it was drizzling, but it was the only day we could visit. Joe and Emma were with us. It was incredibly beautiful because the rain had colored the sand in ways we would not have seen on a sunny day (see above).
They allow visitors to hike AND they allow sand-sledding and snowboarding on the dunes!
In addition, there are multiple campground sites to choose from. Definitely and must-see! See more photographs of Great Sand Dunes National Park
