Introduction:

The Bentonite Hills near Hanksville, Utah, offer a surreal and vividly colored landscape that looks like it’s been transported from another planet. These hills are famous for their striking layers of red, blue, purple, and gray clay, creating a vibrant and otherworldly scene that attracts photographers, hikers, and geology enthusiasts. The unique terrain of the Bentonite Hills makes it a must-see destination for anyone exploring the San Rafael Swell region, providing an unforgettable visual experience that’s unlike anything else in Utah.

How to Get There:

The Bentonite Hills are located about 12 miles west of Hanksville, Utah. To reach the hills, take UT-24 west from Hanksville for approximately 10 miles. Turn right onto Cow Dung Road, Yes really, Cow Dung! Follow this road for about 2 miles, and you’ll find yourself surrounded by the colorful hills. The road is unpaved and can be rough, especially after rain, so a high-clearance vehicle is recommended. Be cautious if the ground is wet, as bentonite clay becomes extremely slippery and can make driving hazardous.

Parking Information:

There are no formal parking lots at the Bentonite Hills, but you can park your vehicle along the side of Cow Dung Road or on any flat, stable area near the hills. Ensure that your vehicle is parked safely out of the way of other travelers and that you do not block the road. The area is remote, so there are no facilities like restrooms or trash bins, so plan accordingly. Be prepared to hike from your parking spot to explore the hills up close.

Description of the Landscape:

The Bentonite Hills are renowned for their vibrant colors and unique textures, formed by layers of bentonite clay that have eroded over time. The hills appear as a series of undulating waves, with bands of red, blue, purple, and gray creating a stunning and colorful landscape. The clay-rich soil gives the hills a smooth, almost polished appearance, and the colors shift and change depending on the time of day and lighting conditions. The stark beauty of the landscape is accentuated by the lack of vegetation, giving the area an otherworldly, almost Martian feel. This is a place where geology takes center stage, offering an incredible opportunity for photography and exploration.

Trail Difficulty and Length:

There are no official trails in the Bentonite Hills, which means visitors can explore the area freely. However, the terrain is rugged and uneven, with soft clay and loose rocks, making it moderately difficult to navigate. The lack of marked trails also means you’ll need to be cautious and aware of your surroundings, as it’s easy to lose your bearings in the rolling hills. Hikes can range from a short stroll to several hours of exploration, depending on how far you wish to venture. The hills are relatively small, but the challenging terrain and potential for slippery conditions, especially after rain, mean you should take your time and hike with care.

Is Bentonite Hills Dog-Friendly?:

Yes, the Bentonite Hills are dog-friendly! Dogs are welcome to explore the area with you, but they must be kept on a leash at all times. The soft clay and uneven terrain can be challenging for some dogs, so consider your pet’s abilities before bringing them along. Be sure to bring plenty of water for both you and your dog, as there are no water sources available in the area, and the desert environment can get hot, especially during the summer. Additionally, please remember to clean up after your pet to help keep the area clean and enjoyable for everyone.

Local Regulations:

When exploring the Bentonite Hills, it’s important to follow local regulations and protect the fragile desert environment. Since there are no official trails, practice Leave No Trace principles by avoiding trampling vegetation and staying on existing paths whenever possible. The bentonite clay is particularly susceptible to erosion, so avoid hiking in the area when the ground is wet to prevent damaging the landscape. Pack out all trash and dispose of it properly to help preserve the beauty of the hills. Given the remote location, be prepared with plenty of water, sun protection, and a first aid kit. Cell service is limited, so make sure someone knows your plans before you head out.
