There is so much to do at USNWC that you could easily spend an entire day there. The raft guides are really a lot of fun. We went on several trips down both sets of rapids, both forwards and backwards, so we got to experience different levels of difficulty. As a local, I come at least a dozen times a year just to bike. I bring my own bike and ride the trails for free. The trails are great for anyone from novice to experienced mountain biker.
