The winter landscape at Craters of the Moon is one of black and white. Deep snow obscures the once fiery lava. Dark, jagged rocks protrude here and there through the backdrop of snow. It is a landscape of dramatic contrasts and rugged beauty.
During the period before and after the Winter Trail is actively groomed, there is a brief period when the Loop Road is still closed to motorized travel but is open to other types of access. This car-free period is a great time to hike or bike the Loop Road. Bicyclists should be aware that snow, ice, and water are likely to be on the road and depending on conditions, snowbikes may be necessary to ride the Loop Road. Dogs on leash are also permitted on the roadway, but not on trails, during this time. Please pick up after your pet.
Snow removal operations in the spring may require temporary closures. Portions of roads and hiking trails (including the caves) may remain covered in snow and ice well into May, so plan accordingly.
Although the Loop Drive is closed to motorized travel in the winter, those who are properly prepared can explore the monument on our winter trail. The winter trail is groomed as snow pack and staffing allow. This is usually during the period from December to March.
The groomed track is 4-7 miles in length with mostly level terrain or gentle hills. There is one steep hill on the southwest flank of Inferno Cone. Novices should ski the loop clockwise to avoid coming down this hill. Although skiing time varies with ability and snow conditions, most people can ski the entire loop in 2 to 4 hours. There is no charge for skiing at Craters of the Moon. For more details on the Winter Trail conditions (click on the Craters of the Moon tab)....
The open slopes of the cinder cones scattered along the Loop Drive provide perfect telemarking terrain. Skiers should feel free to leave the groomed track and venture onto these slopes to carve some turns!
Weather conditions may change rapidly and skiers should be prepared for the worst. The average high temperature for January is 29 degrees F and the average low is 10 degrees F. Even on the best of days, wind is common. Carry extra clothing, water, and a snack. Know your own abilities and do not ski so far that you become exhausted. Use caution if you leave the groomed track. The surface of the lava beneath the snow is very uneven and may conceal cracks and sharp rocks.
Dogs tear up the groomed track and detract from the skiing experience for others. They may also frighten wildlife. For these reasons, dogs are not permitted on the ski track. Bicycles are also not permitted on the Winter Trail.
The snow-covered landscape of Craters of the Moon offers many opportunities for visitors on snowshoes to enjoy the monument during the winter months. Follow the orange snow poles to explore a 1 mile Snowshoe Loop Trail through the monument or venture off of the winter trails and climb a cinder cone. Snowshoe Walks are scheduled for groups and individuals on Saturdays in January and February and no prior snowshoe experience is required.
