For the most part, there aren't many. There are a few places with particularly dangerous water (Upper Basswood Falls for instance) but these are usually marked on a map or pointed out by your outfitter. Bears can be a problem, but a bear barrel or rope usually does the trick. Keep your camp clean. Having too much of a good time is always a possibility!
