It is a fantastic guide to all things Alaskan. www.milepost.com or your favorite book store. I spent quite a bit of time in the Denali area (there is both a state park and a national park). Most people see only a tiny bit of either. Used to be you could get around with fewer rules. We had more scares with moose than with bears, but follow the rules for both. If you see a mother moose with calf.....don't mess with her. She can get upset very easily. Be prepared to be wet, cold and more wet. Remember that there are no tall trees nor big shrubs so 'bushwacking' isn't the same as in a jungle. Glad I visited when I did.
