Jackson Hole is the commonly used name for a valley that lies between two mountain ranges, the Tetons and the Gros Ventres. The town of Jackson is a piece of the Old West, where cowboys stroll the boardwalks, and bars serve the best steak and game in the world. Jackson is the gateway to both Grand Teton National Park and Yellowstone National Park. The area offer fly-fishing, river rafting, wildlife viewing, and hiking. Yellowstone boasts two million acres of geologic wonders and protected bison, elk, bear, moose, and eagles. The star of Yellowstone is still Old Faithful, a geyser that puts on a spectacular show every 60 to 110 minutes.
