This campground has three loops, the first two have sites for RVs, and the last loop is for tents only. There are hiking paths from the campgrounds out to the dunes, and it's only a three minutes drive to the dunes parking area. There are bear boxes and all trash containers are bear proof, they do see bear here so use the boxes properly. It's $20 a night, or $10 if you have an Access pass, and you can stay 14 nights every 30 days. You will need to make reservations if you want to stay the full 14 days, as the walk up sites are few and far between and you'll have to move every couple of days if you don't have reservations. The Point of no Return 4wheel only road is at the beginning of the campground and has camping down it, but that's another campground and another review. There are plenty of trails to hike, both up the surrounding mountains, and to the dunes. The weather I'm August is beautiful, it can get hot so pack plenty of water with you. There is a free RV dump and fill station right before you get into the campground, great even if you don't stay at the park. The camp store is rarely open and limited on items, so prepare before you head here. The visitor center is not far and that's where you get your permits for overnight backpacking, parking, camping in the park. This place is like being on another world, views are truly breathtaking. If you only stop one place in the San Luis Valley make it the Great Sand Dunes National Park, you won't regret it.
