All next week the trails and walkways at the Jenny Lake area of Grand Teton National Park are scheduled to be closed to the public as a safety precaution while helicopters haul in materials for trail work in the Hidden Falls and Inspiration Point areas.

The closure is to begin Monday and run through Sunday, October 22. However it could be lifted earlier if the work is completed sooner than expected or weather conditions force a delay, park officials said.

Trails leading from Jenny Lake's southeast shore to Hidden Falls and Inspiration Point will be temporarily closed to all public access. Walking paths around the Jenny Lake Visitor Center will also be closed intermittently. Lake access from the public boat launch will not be allowed.

All visitor services in the Jenny Lake area, including the shuttle boat and visitor center, are closed for the season. Signs will be posted throughout the closure area, and park staff will be positioned to provide suggestions for alternate routes for anyone visiting this area of the park.

Areas not affected by this temporary public closure include the Teton Park Road, Jenny Lake scenic loop road, access to Jenny Lake via the String Lake trailhead, access to Cascade Canyon via the horse trail bypass, and access to the Lupine Meadows trailhead.

This construction work is part of the Jenny Lake Renewal Project, a $19 million public-private partnership between the National Park Service and Grand Teton National Park Foundation. The project will enhance the visitor experience at the park's most popular destination for generations to come. 2017 is the fourth of five major construction seasons.
