Kayak through the canyon, a perfect way to experience UT. Drive around the dunes and find your own site for camping, but there are toilet facilities to make it similar to a standard state park campground. They don’t take reservations so come early in the day. There are other more developed campsite options in the park (some do take reservations). If it’s windy the sand can be a problem, but that’s just how Utah is. There’s so much more to do in the area too and the sunrises & sunsets are memorable.
