Main image

Jenny Lake is a glacially formed lake in Grand Teton National Park, Wyoming, situated at the eastern base of the Teton Range near the small community of Moose. The lake occupies a basin carved by Pleistocene glaciers and serves as a major trailhead and recreation area within the park. Popular on-site features include a seasonal boat shuttle that crosses the lake, short hikes to Hidden Falls and Inspiration Point, and the longer Cascade Canyon route that begins at the lake. Trails around the lake provide close views of the Teton peaks and are used for hiking, wildlife viewing and photography.

  • Boat shuttle access: A seasonal boat shuttle crosses the lake to shorten the hike to Hidden Falls and Inspiration Point and to access the Cascade Canyon trailhead.
  • Best viewing times: Best light for reflections and photography is often early morning or near sunset when winds are calmer and the Teton peaks reflect on the lake surface.

What to See #

  • Hidden Falls and Inspiration Point: Hidden Falls and Inspiration Point are reached via the short trail from the Jenny Lake shuttle landing, offering a popular short-hike option to a waterfall and a cliff viewpoint over the lake.
  • Cascade Canyon trailhead: The Cascade Canyon trailhead starts at the western edge of the lake and leads into a major Teton backcountry corridor with multi-day hiking routes.
  • Jenny Lake Loop: The Jenny Lake Loop is a lakeside trail that circles the shoreline and provides close views of the Teton Range; the loop is a multi-mile hike used for day outings and wildlife viewing.

How to Get to Jenny Lake #

Jenny Lake sits inside Grand Teton National Park, about 12 miles northwest of Moose, WY. From Jackson, take US-191/US-26/US-89 north to the park road; the Jenny Lake parking area is clearly signed off Teton Park Road (about a 30-40 minute drive from Jackson). The seasonal shuttle boat launches from the lakeshore; trailheads for Hidden Falls and Cascade Canyon begin at the eastern shore.

Tips for Visiting Jenny Lake #

  • Take the shuttle boat across Jenny Lake (seasonal) to cut off about 2-3 miles and begin Cascade Canyon from the west side.
  • Arrive before 8:00am for glassy reflections and far fewer people; late afternoon light on the Tetons is also superb.
  • If planning Cascade Canyon, pack layers-storms blow in fast and the canyon stays cooler than the flats.

Best Time to Visit Jenny Lake #

Best in summer for access and boat service; shoulder seasons offer fewer people and dramatic light.
