It's not just about having a knack for choosing less busy days in Yellowstone National Park. There are rules involved and permits to get if you'd like to do some backcountry camping in the first national park for all to enjoy.
As part of an ongoing Bison Conservation Transfer Program, 116 Yellowstone National Park bison were relocated to the Fort Peck Indian Reservation in Poplar, Montana, in early February.
Yellowstone Park technically never closes, but most of the roads do. Beginning November 1 there are just two gates open (weather permitting) throughout the winter.
