While there are several places that look like this in Southern Utah, the best places to see this Mars landscape is the Bentonite Hills Utah.
As you take the 4×4 only road to get to that part of Capitol Reef, you’ll notice a variety of landscapes on the way including the striped hills that give the area the Mars look.
Remember to also practice Leave No Trace if you decide to climb up the Bentonite Hills. There are no official trails in the Bentonite Hills.
Be careful though – some of the previously distrubed areas along the washes down the hills have deep holes going down into the hills.
If you go through Hanksville, make sure to eat at Duke’s Slickrock Grill. Get the cornbread – you won’t regret it!
