Please be responsible when using the great outdoors. Snowmobiling is not allowed in designated wildlife winter ranges or Wilderness Areas. Snowmobilers need to be careful to not damage vegetation by riding only where there is adequate snow cover. Hikers and other motorized users should be aware that some trails and areas are closing, even though they may still be passable due to the lack of snow.
Maps are available at any of the Forest Service offices of the Caribou-Targhee National Forest. Winter recreationists are urged to obtain a current map before traveling in the Forest. You can also find maps and other useful information available for free online at https://go.usa.gov/x7yjg.
