I believe there are some around Greybull if you want to be near town, The mountain camp ground are rustic at best. I never hunt on that side of the mountain , so my experience is limited. This (the east of the Bighorns), are two general area tags for residents, If you want to see crowded come over here......... The campgrounds should not be too full depending on the services you desire, a lot of retired tourist stop in the Greybull area on their way out of Yellowstone.
