Many of these are not your average trail.
Many trails are planks raised over the wet ground to protect both the environment and hikers' feet.
However, the raised planks may not be enough to keep your feet dry, so check with district offices for the appropriate foot gear before you go. And speaking of bears, remember, you're in their territory. Always make your presence known. They don't want to be surprised any more than you do and will avoid you if they can. For current trail conditions, check with the local Forest Service office.
