Is this south central Colorado or the Sahara? It’s not always easy to tell at this unique park where the continent’s tallest sand dunes join Colorado's rugged Sangre de Cristo mountains at Great Sand Dunes National Park. Wander, sled or sand-ski among the dunes, or, even better, backpack out to camp in the sand. Bonus: Dogs are welcome. PC: Lionello Delpiccolo (nationalparktrips, Jul 2019)
