Lots of various caves, including the main one. The 10m long duck was no where near as bad as it sounds, but I turned round when I got to the bottom rather than attempt a through trip in just my normal undersuit, when there is meant to be a short free dive on route. I entered the lower entrance to have a look but the water proved too cold. Was met with a few Craven cavers who did not go through the 10m duck. We then explored some caves along the same valley names unknown without Grampian guide.
