Greys River Groomed Trails

The Greys River area has some of the best snowmobiling on the planet, offering spectacular scenery combined with abundant wildlife and hundreds of miles of groomed trails. It's a great place for the novice to enjoy snowmobiling. There are also thousands of acres of off-trail riding opportunities which will challenge the most experienced rider.

The main trails are groomed every other day and secondary trails are groomed every other week. This trail system is maintained through cooperative efforts of the Wyoming Department of State Parks and Cultural Resources/Division of State Parks and Historic Sites, the U.S. Forest Service.
