Restricted vehicle access and limited services make winter visits far different than the summer experience. Every year in early November, most park roads close to regular traffic to prepare for the winter season. The only exception is the road between Mammoth Hot Springs and the northeast entrance, which is open to regular traffic all year. Around mid-December, roads open to limited snowmobile and snowcoach travel. This means the only way to visit Old Faithful, the Grand Canyon of the Yellowstone, and other popular destinations during winter is by guided snowmobile or snowcoach, or through the non-commercially guided snowmobile access program. Winter travel ends in mid-March, when plowing crews begin clearing a winter’s worth of snow. Roads start re-opening to automobiles in mid-April.
