This is one of the most picturesque places to camp. Surrounded by mountains and right on the Shoshone River, this is a bit of Heaven on earth.
There is only one flush toilet/(paid) shower facility in the North Fork campground (none in Lake Side), but there are accessible vault toilets within walking distance from anywhere. The tent sites have HUGE tent pads, plenty of room for our 9x12 cabin tent and solar panels. All sites have large concrete picnic tables and the tent sites have privacy walls which are separate to the tent pads. And the tent sites are spaced very far apart, so you never feel cramped.
Cody, WY is pretty close if you need to stock up on supplies and Yellowstone is just 44 miles down the road.
