There are so many wildlife in Yellowstone National Park. You will see them if you spend just a day in the park. Of course, being able to take a good shot of any is a totally different story.
For sure you will see Bison. At first it was exciting, but after seeing them every day, and as they stroll so slowly and block the way, it was actually annoying. They are definitely not the prettiest animals.
