You do have to be prepared to pay something to get to the park. There are lots of wildlife and sightseeing tours you can take advantage of as well as visiting the geysers. There are some excellent outfitters that will take you into Yellow Stone on wildlife expeditions led by biologists. There are also companies that do private fishing, biking, and horseback riding tours. Someone will take you on a tour into the back country to view wildlife or just experience this incredible area. They even have hunting guides that will take you hunting for elk and deer.
