Grassy Lake Campground offers 20 primitive campsites along a gravel road in the John D. Rockefeller Jr.

Memorial Parkway, available free on a first-come, first-served basis starting June 1st, with vault toilets, bear-resistant food storage, and fire pits but no potable water.

The remote location near Grassy Lake Reservoir provides access to fishing and hiking between Grand Teton and Yellowstone National Parks, though the long dirt road access and intense mosquito activity in summer are notable considerations for visitors.
