Hey James,
Sorry for the delay in getting back with ya. Its great. I think it was either 5 or 10 bucks for a pass to get in but it was a two day long pass. I stayed at the Wolf Inn which is right across the street from it, walking distance. They have feeding times through out the day and they mark them down so you can come and go as you please to see them when they are most active. There are also some grizzlies there although their habitat isnt very natural looking in the background. Here are a few more wolf images from the discovery center that I took. Take care, Scott
