Hiking
Hike to your heart's content in the backcountry where no permits are required, or choose one of eight trails, which range in difficulty from easy to strenuous (quarter mile to 10 miles roundtrip). The park allows biking only on paved and unpaved roads; the loop road is narrow, so exercise caution.
Camping
Choose the improved campgrounds with flush toilets, potable water and covered picnic tables, or the primitive campgrounds with picnic tables and pit toilets on an unpaved road.
Wildlife
View the successfully reintroduced black-footed ferret and see swift foxes, bighorn sheep and bison. For your protection, stay 100 yards away from all wildlife.
Lodging and Dining
The Cedar Pass Lodge, its dining room and gift shop are open from mid-April through mid-October.
