Killpecker Sand Dunes in Rock Springs, WY
It's hard to argue with a name like Killpecker Sand Dunes. One of the largest active sand dunes in North America, the desert-like landscape stretching for 100 miles just north of Rock Springs, WY, is a nature-made, giant sandbox for death-defiers.
The dunes are popular with hikers but are a huge draw for off-road vehicle enthusiasts. Dune buggies, dirt bikes and ATVs get 11,000 acres – nearly 20 square miles – in a designated open play area.
Most dune areas have smaller dunes and flat areas for beginners, but the nearly 109,000 acres also provide plenty of dunes more than 100 feet tall – some up to a mammoth 150 feet. If the landscape isn't extreme enough for you, just stick around – the steep ridgelines are constantly shifting as winds rearrange the dunes.
