National Park is a United States National Park in northwestern Wyoming
. Approximately 310,000 acres (130,000 ha) in size, the park includes the major peaks of the 40-mile (64 km) long Teton Range
as well as most of the northern sections of the valley known as Jackson
Hole.Grand Teton National Park is named for Grand Teton, the tallest mountain in the Teton Range.
Grand Teton National Park is an almost pristine ecosystem and the same species of flora and fauna that have existed since prehistoric times can still be found there. More than 1000 species of vascular plants, dozens of species of mammals, 300 species of birds, more than a dozen fish species and a few species of reptiles and amphibians exist. Due to various changes in the ecosystem, some that are human-induced, efforts have been made to provide enhanced protection to some species of native fish and the increasingly threatened Whitebark Pine.
Grand Teton National Park is a popular destination for mountaineering, hiking, fishing and other forms of recreation. There are more than 1000 drive-in campsites and over 200 miles (320 km) of hiking trails that provide access to backcountry camping areas.Noted for world-renowned trout fishing, the park is one of the few places to catch Snake River fine-spotted cutthroat trout. Grand Teton has several visitor centers that are managed by the National Park Service and concessionaire managed facilities which operate motels, lodges, gas stations and marinas.Visitors are allowed to snowshoe and do cross-country skiing and are not restricted to trails.The Craig Thomas Discovery and Visitor Center adjacent to the park headquarters at Moose, Wyoming, is open year round.
