One of our visitors' favorite things about Yellowstone National Park is getting the chance to spot plenty of different species of animals and plants. In fact, Yellowstone is home to more than 1,000 species of plants and more wild animals than almost anywhere in the US. We could fill a book with all the animals, plants and flowers you're likely to see during your Yellowstone visit, but here are just a few examples of the flora and fauna you might spot.
