In late October, hundreds of elk congregate in the Slippery Ann area of the park. Dozens of cars also come to watch the herd. It's a very fun time, and an amazing spectacle. It is very busy at this time of year, so that's a bit of a bummer for camping. In mid-summer, before the elk come, there are a million-zillion mosquitoes and it's not fun. Come for the elk!
