Jenny Lake’s 20 miles north of Jackson, past Moose, and just south of Jackson Lake.
Carved by the same glaciers that created Cascade Canyon, it’s roughly 420 feet deep and spreads across 1,200 acres.
It was named after a Shoshone Indian woman who married Englishman Richard “Beaver Dick” Leigh. She and their 6 children met a tragic end when succumbing to smallpox in 1876.
The Jenny Lake Visitor Center is a very popular spot. If you want to contact the Center, its phone number is (307) 739-3392.
Jenny Lake is one of only two lakes in Grand Teton National Park that you can enjoy your motorboat on. There’s an easy 7-mile trail, the Jenny Lake Trail, looping around the lake. If you don’t want to do the walk, there’s a passenger ferry that will take you across. For more info on, go here: https://zurl.co/q0rZl
By the way, the lake’s northeastern shore is usually the quietest one.
As of a few years ago, her waters are still classified by environmental testing as pristine and not impacted by pollution.
