Absolutely gorgeous! It's very tiresome, but that's to be expected. I wouldn't recommend renting a sled in the winter, seeing as you have to pay extra if it touches snow. That said, there is nothing more exciting than flying down these hills. Keep me mind, it is almost impossible to leave here without you and all your friends covered in sand! I can't wait to go again with my camera if I can it's absolutely beautiful! I also love the visitors center. It has a good gift shop and an amazing view. You also learn a lot about how they were formed and the significance to other cultures. 10/10 recommend
