Fossil Butte National Monument is located in the sagebrush-covered hills of rural, southwestern Wyoming. Wide open spaces, fresh air, blue skies, abundant wildlife and, of course, some of the most incredible fossils in the world are found here.

The visitor center and museum are open year round, though hours vary by season. Ranger-led programs are offered during the summer.

During the summer months, hiking trails provide a wonderful way to experience the monument. Spring and fall offer cooler temperatures and many chances to view wildlife. Snowshoeing and cross-country skiing are great ways to explore the park during winter months.

There is no camping, lodging, or restaurants in the park, but there are options in the local communities. Kemmerer and Diamondville are 12 miles from the park. Further away are Cokeville, Evanston, Green River, and Rock Springs.
