If you have a whole day add the following stops to those suggested for the half day visit:
Stop at the Willow Flats Turnout, 6 miles south of Colter Bay, for a view of an extensive freshwater marsh that provides excellent habitat for birds, beavers and moose. Jackson Lake and the Teton Range for the backdrop.
Located one mile east of Jackson Lake Junction, this cut-off meander of the Snake River attracts a wide variety of wildlife. Mount Moran, the most massive peak in the Teton Range, dominates the background.
Jackson Lake Dam Overlook
Jackson Lake Dam, one mile west of Jackson Lake Junction on the Teton Park Road, raises the level of Jackson Lake a maximum of 39 feet. In addition to being a reservoir, Jackson Lake is also a natural lake formed by an immense glacier that once flowed from Yellowstone National Park. Park on the southwest side of the dam and take a short walk for a peaceful view of Jackson Lake and Mount Moran.
South Jenny Lake
Park at South Jenny Lake and take a short walk to view glacially-carved Jenny Lake nestled at the base of the tallest Teton peaks. A 6-mile hiking trail encircles Jenny Lake. Shuttle boats (early June through late September) provide easy access to the west shore of the lake and trails to Hidden Falls, Inspiration Point and Cascade Canyon. Parking is limited and the trail becomes crowded, so plan to arrive early or late in the day. A midday arrival will be frustrating.
Antelope Flats-Kelly Loop
At Gros Ventre Junction, 5 miles south of Moose Junction on Highway 26-89-191, turn east. Follow the road to the small town of Kelly. To see the Gros Ventre Slide, turn at the sign marked national forest access. The Gros Ventre Slide occurred in 1925 when earthquakes and rain caused the north end of Sheep Mountain to break off and dam the Gros Ventre River, forming Lower Slide Lake. Follow the Antelope Flats Road along hayfields and ranches to rejoin Highway 26-89-121.
