Colter bay....where to relax after Yellowstone and much more accessible. Colter bay has 200-300 camp sites nestled in under the trees. It’s crowed but workable. First come first serve. Get there in the AM and getting a spot is easy. Do not wait till 4pm. You pull your trailer, motor home, parallel to the camp site.
Know National Park rules, this is not forest service land and the rangers will enforce their rules and regulations accordingly. As with any National Park the best of the Park lays outside the your campsite. The views of wildlife and landscape are everywhere.
