Along Grassy Lake Road in John D. Rockefeller, Jr., Memorial Parkway, this free National Park Service campground provides 20 developed sites stretched along a dirt and gravel route that continues west toward Idaho. The road serves as a backcountry corridor between Grand Teton and Yellowstone, with sites numbered sequentially from the entrance.
The first seven to ten sites feature vault toilets, fire rings, picnic tables, and daily trash service, while later sites become more primitive. Several sites accommodate multiple tents or RVs, with some designed for dual occupancy. Lucas S. found his site offered a "very beautiful view of the Tetons and right along the river." Small creeks run near many sites, providing water access and ambient sound, though mosquitoes can be intense during summer months.
The 14-day limit and free cost make sites highly competitive, especially on weekends. Campers frequently report driving the entire road to find availability, with earlier numbered sites filling first. Rangers patrol regularly to check compliance and coordinate with daily sanitation crews. The road continues past developed sites for dispersed camping opportunities, where Ryan found a spot "next to a little creek and a bridge" after driving 30 minutes beyond the last developed site.
Wildlife activity includes bears, requiring proper food storage practices. The campground serves as a staging area for accessing both national parks and nearby dispersed areas like Grassy Lake Dispersed Camping to the northwest. Road conditions can challenge low-clearance vehicles during wet weather.
Arrive early in the week for better site availability, and pack insect repellent for summer visits.
