Grand Teton National Park is a United States National Park located in northwestern
Wyoming, south of Yellowstone National Park. The park is named after Grand Teton,
which at 13,770 feet (4,197 m), is the tallest mountain in the Teton Range.
The mountains were named by a French trapper who viewed them from the Idaho
side of the range and called them tétons, the French word for "nipples"
or "teats" (presumably referring to the shape of the peaks). It was
established as a national park on February 26, 1929. The park covers 484 mi²
(1,255 km²) of land and water.
There are nearly 200 miles (320 km) of trails for hikers to enjoy in Grand
Teton National Park.
