The areas around the Grand Teton mountain range and its lakes were established as a national park in 1929 in order to protect the land from commercial exploitation. The protected area was extended into the surrounding valley in 1950. This truly special federal park boasts a diverse ecosystem with 310,000 acres of terrain ranging from summertime wildflower meadows to rushing whitewater streams. These ancient mountains also contain some of the oldest rocks in the National Park Service, dating to nearly 2.7 billion years ago.
There are also numerous serene lakes with deep blue pools, echoing the stillness and color of the glaciers that shaped them. The wild and winding Snake River descends through the park in a rush of water and the dense forests blanketing the mountainsides provide habitat for a vast array of fauna and flora, with some species dating back to the prehistoric era.
Visitors to the park enjoy many outdoor activities including nature hikes, biking, climbing, fishing,and boating.
Although the entrance gates are open year-round, Grand Teton National Park has areas that close for winter and many of the facilities and visitor centers are closed on Christmas Day.
