Walk the bike through Paw Paw tunnel. A hybrid would be ok - a tourer with wide tires would work. A couple years ago when we rode the trail, there was one stretch of about 2 miles across the river from a power plant where they used some stones that were too large on the path. That stretch (if it is still in that state) was challenging even on a mountain bike. I wouldn't try to ride that stretch one any sort of road bike - regardless of tire width.
