Grand Teton National Park is a United States National Park located in northwestern Wyoming, south of Yellowstone National Park. The park is named after the Grand Teton, which, at 13,770 feet (4,197 m), is the tallest mountain in the Teton Range.The name "Tetons" originally was intended to describe several hills near the town of Arco, Idaho. They were named by a French trapper who thought that they resembled a very specific part of the female body. Many years later the name was mistakenly applied to the mountains of present day Grand Teton National Park due to the poor map-making and map-reading standards of the time.
My ideal easier hike in the area that is easy to get to if you find parking in peak summer/. Trail is busy and can get slow moving but once you arrive to the falls and the mist is spraying your face and the sound is so loud you almost yell to talk,. its all worth the trek.
Did this several years ago and it is a beautiful drive. For me, I'd include about another 30 miles or so south as well.
