If you are one of the few visitors who visits the John D. Rockefeller, Jr. Memorial Parkway during the winter, your experience will be vastly different than that of a summertime visitor.  Gone are long lines of cars and motorhomes filling the park roads.  Gone is the twittering of birds, the rustling of aspen leaves, or the background hum of voices.  Instead, you are experiencing a cold, white wonderland.

Cross-country skiing and snowshoeing
Opportunities abound for cross-country skiing and snowshoeing in the Flagg Ranch area of the John D. Rockefeller, Jr. Memorial Parkway.  Unmarked trails follow scenic terrain that ranges from easy to difficult.  These activities are great ways to experience the exhilaration of winter.  Watch for wildlife such as moose, coyote, and ermine, and look for signs of wildlife in the snow.  Be safe, be prepared, and enjoy your time exploring the quiet beauty of winter.  A map of available parkway trails is posted at the Flagg Ranch Information Station.

Yellowstone Access
Flagg Ranch is the closest point to Yellowstone National Park open to automobiles in winter. Automobiles may not travel beyond Flagg Ranch. In winter, Yellowstone is accessible only by guided snowmobile and snowcoach tours, or by self-guided cross-country ski tour.  Contact an outfitter for further details about guided tours. Commercial guide services operate out of Jackson, WY and other Yellowstone gateway communities.
