A popular thing to do at White Sands National Monument is to sled down the dunes. You can buy a sled at the gift shop next to the Visitor’s Center and sell it back for a fraction of the price when you’re done. Our sled was around $16 and we sold it back for $5. There are also blocks of wax you can buy for around $2 or $3. You rub the wax on the bottom of the sled and and it increases your speed. It’s also helpful to find an area where someone else has already packed the sand down for you. This was more fun than we expected and our dog Rachel wanted to join in as well.
