In spring and summer, mountain and valley hiking trails wind through a world dressed in wildflowers. Wildlife abounds, from black bears and grizzly bears to bison, elk, mule deer, moose, pronghorn and coyote. Wildlife safaris led by biologist guides tour the best viewing sites. More than 300 species of birds, from bald eagles and mountain bluebirds to trumpeter swans and sandhill cranes, can be found in Jackson Hole alone.
For fly fishermen, the Snake River is a haven for the local cutthroat trout, as well as rainbow, lake and brown trout. The Snake River is also a magnet for scenic and white-water rafting. Canoeing, kayaking and other water sports are popular.
Mountain biking is big sport in Grand Teton National Park and in the adjoining national forests where single track trails are rife. The Tetons have long been America's main range for mountain climbers. Hot-air ballooning above Jackson Hole is an exhilarating start to a summer's day. Golfers get to choose between two 18-hole championship courses. There is cowboy theatre too with a rodeo in town twice a week throughout summer.
