More than 380 miles of well-marked, groomed trails offer snowmobilers nearly every kind of terrain imaginable for winter fun in the fabulous Trinity Mountains.
Every snowmobile operated on private or public land must be registered with the Idaho Department of Parks and Recreation on or before November 1 of each year.
Follow the basic rules of snowmobiling: don't ride alone, wear protective equipment, and bring adequate supplies.
Check Mountain Home Ranger District's website for a map of the area and available campgrounds.
