Yellowstone / Teton Alternative Camping Recommendations

In between the two, there are probably several places to stay. Of two that I know of Lizard Creek campground, with some good sized sites, and depending on the size of your rig - Grassy Lake road which is past Flagg Ranch. We drove down that road and for smaller rigs, there are several free campgrounds along with pit toilets, along the river. Google Flagg Ranch Headwaters Lodge & Cabins using Google Maps. Follow Grassy Lake Rd and you'll see at least three spots.
