In Lamar Valley, the bison, moose, and pronghorn have their calves while black bears and wolf pups emerge from their den. Grizzly bears can be found along roadside meadows and marmots and ground squirrels frolic in the fields.

Buttercups, shooting stars and pasque flowers are the first blooms of the year to be joined by glacier lilies and bitterroots. A chorus of frogs sing in the wetlands throughout the park.

Yellowstone Park spans nearly 3,500 square miles across the states of Wyoming, Montana, and Idaho. There are five entrances to Yellowstone (North, North-East, East, South, and West) but only the North entrance (Mammoth) is open in the winter.
Because of its size, remoteness and the multiple entrances, it’s hard to pick an idea airport or approach. The closest airports are Bozeman Montana (BZN), Billings Montana (BIL), Cody Wyoming (COD) and Jackson Wyoming (JAC). There is also limited seasonal commercial service into West Yellowstone Montana (WYS). The price conscious flier could look into Salt Lake City Utah (SLC) or Denver Colorado (DEN) and drive in the rest of the way. Be sure to compare flight prices to the various airports to find the best price.
