Want to know more about St. Anthony and all of that sand? Listen up …

Ten thousand years ago, Eastern Idaho was cooler and wetter, providing fertile ground for a variety of wildlife including one-humped camels, mammoths, pony-sized horses, and large bison. Over time, the shrinking of gigantic lakes in the area due to climate warming contributed to the formation of the St. Anthony Sand Dunes , which now cover nearly 10,000 acres and reach heights of up to 400 feet. Whether you're seeking the thrill of racing over the sand in an ATV or a nature enthusiast eager to explore unique landscapes, be sure to add time to stay and play in St. Anthony!

Ride the Dunes

If you feel the need for speed, you can hit the dunes by land and by air! Licensed tour operators like Idaho Extreme Adventures take to the sky for an aerial adventure. Get the big picture of St. Anthony’s famous geologic feature from above, view the dune-creating lakes, and see lava tubes, including the Civil Defense Cave landmark. 

If you want to stick to the dunes by land, off-road enthusiasts have miles of open terrain to explore on ATVs, dune buggies, and dirt bikes. Make the trip with your machines or rent all you need at Dune Excursions or St. Anthony Sand Dune Rentals in town. Or, reserve a ride at PMS Dune & Snow Rentals, the dunes’ only onsite rental shop.

Hit the Trail

It’s time to make a Beer Run! Spring, Summer, and Fall, the Beer Run Trail is an ATV-ers favorite. Fifty-three miles total, this trail is technically easy. Kick-off through desert cattle land and head into the dense forests lining the Island Park Reservoir before riding the rugged terrain alongside the Henry’s Fork of the Snake River. There are a couple of minor ledges along the way, and the trail varies in width. During the Spring, expect deeper puddles, which means you might get all wet!

Other popular ATV dune hot spots include Devil's Dune, Choke Cherry Dune, Dead Horse Bowl, Middle Bowl, and Crapos Hill (aka Thunder Mountain).

A Sandy Summer Event

Those visiting the dunes in early August should prepare for a sandy spectacle with the Idaho Dunes RV Sand Showdown! Watch the races or compete - this is where old school and new school collide for bragging rights in the big dunes!
