You can see rainbow mountains in Utah in two primary locations: Bentonite Hills and Paria Canyon. The most prominent colorful mountains in Utah are located at the Bentonite Hills near Mars Desert Research Station.

The Bentonite Hills consist of blue, red, purple, and green clays created by volcanic ash, giving the hills a ringed rainbow color. While many places in Utah are known to look like Mars, such as Goblin Valley State Park and the Bonneville Salt Flats, people are usually referring to the Bentonite Hills, when they are talking about “Mars,” Utah.

Believe it or not, the Bentonite Hills are free to visit. The Bentonite Hills are on BLM land, meaning no permits, entrance fees or park reservations are required to visit or hike here. Please respect the land and abide by the Leave No Trace Principles when visiting the rainbow mountains.

Rainbow Mountains Utah Hike

There are no specific hiking trails at the Bentonite Hills, but you are free to walk on and hike the Bentonite Hills. Note, the National Park Service requests that you only walk where other people have walked. Off-roading is not permitted. You also cannot visit or hike close to the Mars Desert Research Station.

The Bentonite Hills have a surprisingly squishy, popcorn-like texture, not comparable to any other ground or dirt. This makes walking on the the Bentonite Hills feel like you are actually walking on Mars. Therefore, hiking up the Bentonite hills can be a challenge. As you hike a step up the hill, you slide a half step down the hill. It is definitely possible to reach the top of each hill, just know that it may take you more effort than it looks. Wear proper hiking shoes, no sandals.

Likewise, the Bentonite Hills are known to be the closest environment to Mars, which is why astronomers and astronauts routinely train and perform research in the Bentonite Hills.

Due to the growing popularity of the area, the Mars Desert Research Station recently had to begin managing the public’s access to the area more strictly. “Visitors can view the station from the road, but we require no one approach the buildings or hike in the surrounding area,” said the Mars Desert Research Station on their Facebook page.
