I've been many times and like to camp just below the Micos. Paddle back to camp after running them. Easy to hit the Salto and other rivers from there also.
Town is okay but drive everyday to the water.
The camp is called The Aldea. Easy to find.
On the road to the Micos it will be on the right, just before you head down the hill to the Micos takeout.
I think it is run by huaxteca https://www.facebook.com/Huaxteca
Have a blast bro. It is a special place. Atom....
