Trails in the park are used by a variety of visitors and not all uses are compatible with one another. For the safety of all park visitors, and the protection of the park's resources; bicyclists, snowmobilers, and horseback riders are required to stay on trails designated for their use. Snowmobiling is also permitted on unplowed roadways unless marked otherwise. Trails may be closed temporarily by the park ranger if conditions are wet or otherwise unsafe.
