When clear nights coincide with full moons in the Rockies, the snow-covered landscape can be so illuminated to make it possible to explore after sundown without need of a headlamp. In Glacier National Park, a ranger will help you explore parts of the park under a full moon on cross-country skis, a nice twist to the usual snowshoe hikes.

Come this Saturday and again on February 27 rangers will be leading 4-mile skis to discover how the park’s winter residents survive the cold and harsh months of winter. These guided outings are suitable for intermediate-level skiers of all ages. Of course, the outings are dependent on weather conditions, both those involving the skies overhead and the snow-depth under foot.

These treks begin at 7 p.m. In the event of severe weather or insufficient snow, individuals should call Apgar Visitor Center at 406-888-7939 on the respective weekends to confirm each evening’s outing. All participants must bring their own cross country ski equipment as well as extra layers of clothing, a headlamp and water. Skis are available for rent at retail locations outside of Glacier National Park in gateway communities.

The January 30 moonlit tour will begin at 7 p.m. at the Camas Road gate (a three-minute drive from the Apgar Visitor Center). The February 27 moonlit ski will also begin at 7 p.m., location to be announced. There is no group size limit and no reservations are taken.

Park visitors are reminded that although these winter activities are free, valid park entry is required. Even when entrance stations are not staffed, park entrance fees are required. Upon entering the park, visitors are directed to follow posted instructions to pay entrance fees at self-pay stations. Glacier’s winter entrance fee is $15 for vehicles and $10 for single entrants (hiker/bicyclist/motorcyclist) for a seven day pass.

Annual park passes, valid for unlimited visits to Glacier National Park for 12 months from the date of purchase, are also available for $35 and can be purchased on weekdays at park headquarters and on weekends from entrance stations when staffed.

These “Winter Nights” moonlit ski outings are the first of many special programs that will be offered by Glacier National Park during 2010 as the park celebrates its centennial. For more information or to confirm each moonlit cross-country ski program, please call the Apgar Visitor Center at 406-888-7939, on weekends, between 9 a.m. and 4:30 p.m.
