Paquare river is amazing to raft in.
I highly recommend the Paquare lodge for a few nights if you can swing it. Expensive yes, experience - once in a lifetime. Live off the grid for a few days, but with luxury accommodations.
You have to raft to get there. Class 2 and 3 on the way in and 3 to 4 on the way out. Two spots hit class 5 rapids and it's a serious rush.
Watch out for Bullet ants.
"The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents... some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new Dark Age."
-H.P. Lovecraft
