https://youtube.com/watch?v=bY-0AKUW5D8 This is a Youtube video showing a bunch of people paddling through caves near or on lake Havasu, Az.
Since they are suing day-boats and no PFD, it cannot be too difficult to reach.
Does anyone know where these are and how to find them as I am doing the Topock to Bill Williams stretch this weekend and would like to visit these caves.
