If you like sand, I've got a great place for you to check out. This is the Lake Channel Sand Dunes area managed by the Bureau of Land Management Idaho Falls region. While getting into and out of this bowl of sand can be challenging, the sand itself can offer easy to difficult tracks to choose from. Reaching and exiting the main area of sand requires traversing some rock ledges or steep sandy hills.
This area also offers a nice view of Bonanza Lake and can be reached from Lake Channel Road. It also has a few established camping spots with fire pits and shaded, level spots to post a tent.
