I have been lurking on this group for some time and for some years have been an occasional contributor to uk.rec.scuba on the subject of Maltese Diving and cheap u/w photography using the MX5. I was prompted to sign up as a result of the request for information on Anglesey.
I have dived Holy Island on a couple of occasions. We are budget divers so me and my fellow member of the Bear Necessities Dive Team stick to shore diving.
We use Diving Services at Trearddur Bay (01407 860318) for air fills and there are several good shore dives from the beach opposite the shop and free parking just above. Another good shore dive is from Porthdafarch Beach a few miles North but we found the best dive was on the left of the bay.
We stay at an excellent campsite just half a mile from the dive shop - Tyn Rhos Camp Site 01407 860369 - no need to book it's vast with excellent shower block (25p) washing up room and good toilet block. The cost was very reasonable.
There is plenty of boat diving available if required with some interesting wrecks offshore apparently. A branch of Lidl is present in Holyhead for provisions and booze should you run short.
I have a few photos on
www.photoisland.com using the name ericdv and the password scuba but the vis. although okay for diving was not good enough for my rather cheapo camera.
Although declared as a budget diver I do manage 3 months a year on Malta so anyone wanting any griff on that location feel free to email me.
