Seasonal activities in Ant Hills Wilderness Study Area

The waters in the Monument feature both native fish species and introduced species. Some of the native species you’ll find here include bonytail, Colorado Pikeminnow, Humpback Chub, Roundtail Chub, and Mottled Sculpin. Introduced species are smallmouth bass, burbot, carp, catfish, northern pike, and many more.

Auto Touring

Even though many areas in Dinosaur National Monument are managed as wilderness, there are several road networks that penetrate the rugged interior parts of the monument. As a result, these routes make for fascinating scenic drives, offering dramatic views of the picturesque landscapes, flora, and fauna.

Some of the scenic drive roads are paved while some others are dirt roads that require that your vehicle be the four-wheel drive, high clearance type. Examples of scenic drive routes here are Harpers Corner Road, Yampa Bench Road, and Deerlodge Park.


Guests and campers love to explore the remote canyons in Dinosaur National Monument by rafting on the rivers in the park. Green River, Yampa River. Warm Springs, Hells Half Mile and other water bodies here offer good opportunities to enjoy rafting through rapids.

You may either raft through the rivers on a commercially guided trip or on a non-commercial trip. If you don’t have the experience or necessary equipment, it’s best you sign up for the guided trip on any of Green River or Yampa River. If, on the other hand, you are skilled, have the right gear, and possess a permit, let yourself loose!



You can ride your bicycle on all of the roads within Dinosaur National Monument, so feel free to come along with your bikes. The trails in the Monument are, however, closed to the use of bicycles.

Because of the nature of the paved roads in the Monument – narrow, and usually without shoulders - you will need to take measures to ensure you stay safe. Some of the things you should do include wearing bright-colored clothing and riding single-file.

Some of the places where you can ride are from Rainbow Park to Island Park, along Yampa Bench Road and Cub Creek Road.
