Site Access: Shore entry

The pier is at the end of a wall, to get to it you will have to swim (surface or otherwise) along this wall. There's lots to see and if you fancy venturing out tie a reel to one of the end pier supports and reel out to the reefs.


Site Description:

This really is a lovely dive, even though the surface area is relatively small, there is lots to see and it's not hard to spend a hour here, just meandering under the pier.

Should really be dived 30 mins before high tide to ensure some depth and a sewage outfall discharges on the outgoing tide!

Entry: Free

            
Issues:
  • North-easterlies are the worst winds for this pier; the prevailing south-west wind gives few problems
