Amazing hiking and so much wildlife, even in the winter. It was very cold overnight (0F), but I would still recommend this as a backpacking trip. The campsite are large and flat with close access to water (at least the one we were at). The trails were covered in snow so we couldn't tell if they were well maintained, but there were enough markers and trail signs at every intersection that we always had a good idea where we were.

From September of 2009. We entered the park from the east this early morning and were amazed to see ranger and visitors viewing the Druid Wolf Pack. An awesome site to see. Not the best camera for the distance. P90 Nikon.

Have never seen so many bison in one place. Thousands of bisons together. This place is like Africa's Serengetti national park. You will find the excitement of a safari. Bison and their cubs cross the street at a certain time. Only thing you can do thay time is sit in your car and watch thousands of bison crossing the street.

Best place in Wyoming to watch wildlife. Be there before sunrise and keep good binoculars to see animal activities

So far have seen the most interesting wildlife in this area, particularly wolves.
