Elk Island Campground is a remote backcountry campsite located on an island in the middle of Jackson Lake in Grand Teton National Park, accessible only by boat (approximately 1. 5 hours paddling from Signal Mountain boat ramp).

The site requires advance reservation and is best visited with a group; paddlers should bring maps, bear spray, and be prepared for variable weather and wind conditions on the lake.

This unique island location offers an exceptional backcountry camping experience for experienced paddlers and is also accessible via motorboat or commercial lake cruises.
