The Jenny Lake Boat Concession Facilities, also known as Reimer's Cabin and the Wort Boathouse, are a group of buildings on Jenny Lake in Grand Teton National Park.

The boathouse was built by concessioner Charles Wort, who held the original U.S. Forest Service use permit from the time before the establishment of Grand Teton National Park, when the lands and lake were under the jurisdiction of the Forest Service.

The log cabin is an example of the National Park Service Rustic style.

Plans for the cabin were approved by the National Park Service landscape Division, which also supervised construction.
