If you are one of those lucky people to have Monday off as the Martin Luther King, Jr. birthday holiday, you may want to consider a trip into your national parks for your day off. Grand Teton and Yellowstone National Parks are among the National Park Service sites across the nation in waiving admission fees next Monday in observance of the federal holiday. No matter how you choose enter the park – by car, RV, bus, or on a guided snowmobile or snowcoach trip – the entrance fee to the parks will be waived on Monday. Of course, access to the interior of Yellowstone during the winter months is restricted to guided snowmobile and snowcoach trips from the North, West, South and East entrances. The road from the North Entrance at Gardiner, Montana, through Mammoth Hot Springs on to Cooke City, Montana, outside the park’s Northeast Entrance, is open to wheeled vehicle travel all year. In Grand Teton, the Park Road from Taggart Lake parking area to Signal Mountain Lodge is closed to wheeled vehicles but open to cross country skiing or snowshoeing; as is the Moose Wilson Road.
