Snowmobile Reports – Idaho

Trails Groomed by Fremont County, ID • 208-624-7266 • website

Remember all snowmobiles, regardless of their state/province of origin, are required to purchase an Idaho snowmobile registration. It is the law. All recreation vehicles operating over snow in the winter are required to purchase a snowmobile sticker (A summer OHV sticker is not valid for this activity in the winter). The sticker pays for grooming, plowing of the parking lots and all snowmobile related activities. Without your contribution to the county grooming programs, grooming and parking lot plowing will cease to exist.

NOVEMBER 26th, 2019: Although the weather forecast predicts new snowfall for the Island Park area over Thanksgiving Day, the existing snow depth is currently minimal. The good news is, however, the Caribou/Targhee National Forest is open to snowmobiling starting Thanksgiving Day — if you can find the snow.
