I labeled this a moderate/difficult paddle for a few reasons: The current is strong to fight upstream, and in some spots water is shallow and rocky. Probably should have portaged over it but we're thick headed and refuse to get out and walk when there is an inch or more of water to tread/hand walk the kayak through. :-) The currents also create cross currents in many spots throwing you into the shore which is mostly lined with thorn bushes...Ouch.
However, aside from this difficulty, it is a quiet, beautiful trip through an aesthetic and scenic river/woods. It is well worth the effort upstream to coast peacefully back with the current and enjoy the scenery.
In conclusion, it is a difficult paddle in most spots but well worth the effort. Be sure to brush up on edging skills, and be prepared for portage in some spots (unless you are stubborn like us). I would recommend a touring or better kayak that can cut water well due to the current, and definitely one that can take a "rock beating".
