There are many places to raft and Kayak on the Klamath. The rapids range from Class II to Class IV+. The closest to the house for PUT IN is at the base of the Iron Gate Dam about 8 to 10 miles away and then you can go as far as 47 miles to Scott River. We are going to try this trip this weekend. I will report back where you can TAKE OUT for shorter rides. You can find all the data here at All About Rivers
