Mile 13.3 - This rocky section of trail is not passable on bike but okay
on foot. Even if you have mad mountain biking skills. Up until the 1996 flood,
there was a boardwalk for bicycles and wheelchairs and the park is planning on rebuilding
it. (Update 2006: This section has been repaired and is
either covered with soil or spanned by a small bridge.)
After the repairs in 2006, a board walk was erected which makes passage by bicycle much easier. So long as the geese aren't in your way.
