I am only just beginning to get down class II+ without swims.  However I was wondering what might be a good first class 3 to aim for?   Another question, which whitewater classification do you start seeing waterfalls on?  

Oops, sent you a private message instead of replying here (why that option is the default makes no sense).

To summarize: Lower Green River Gorge is a popular, local class III river.

I haven't seen any true waterfalls in class III, but there are definitely some in the class IV range.

I agree with Derek, the lower green is pool/drop so some drops may seem pretty easy while others can be more challenging. It also has a couple different put-in's.. the top one giving you 3 solid class III's and the lower one missing those first 3 drops, which would most likely be a good place to start for a first descent.

Can't wait to have you down in our neck of the woods (south end) :)

Oh man that sounds good.  My goal is to paddle class 3 comfortably this year, but I also can't wait to do that very first waterfall.  Anybody have some good pics/vids of this particular run?  

I have a few helmet cam videos of the lower gorge. It's one of my favorite runs in the area.

At what water flow (low) does this become a bad spot to try?
