Great place to learn to dive if the sea is rough. Although it is deep, it goes down in steps so the depth can be pitched for the experience of any diver. Over dirt track onto site.
Puffin Island

#9 - Puffin Island

UK, Wales, North Wales

beginner

The island can be dived on any side but the tip nearest the mainland is a good place to finish on your safety stop as the resident seals may come and play with you. ( they only nibble your fins). can be dived as a drift dive but watch out for the pleasure boats who come past regularly in the summer. A smb and good boat cover are a must Puffin Island is also known as Llangoed.

The vessel was about 130 metres long, in two parts, the largest wreck inshore in Anglesey and the most dived. Forward section will be found in the middle of Prth Dafarch bay with the stern against the rocky cliffs to the west. The stern lies close to the cliffs about half a mile south-west of Porth Dafarch beach. Most of this section lies on a rocky seabed. Good deal of fish life. Beware of no clear surface areas at stern end of this wreck. Porth Dafarch

A good secondary site to dive if the other side of the island is blown out by the wind. This site is sheltered most of the time. Dive is around the rocky bottom, looking at a variety of sponge and kelp. Small fish and nudibranch can be found around the plant life. By boat from Holyhead harbour or other nearby launches. The site is near an old stone wall on the cliff face.

A ship carrying musket flints sank here around 300 years ago. No wreckage remains but the occasional flint can be found. Otherwise, look around the kelp and plant life. From the shore near the harbour or as a second dive from a boat.
High Point North

#18 - High Point North

UK, Wales, South West Wales

The bottom of the sea are lined with very large boulders, which give home to the Lobsters. Depths are around 15 m and care must be taken with fishing line, as the fishermen use this area often. In 1996 a 14lb Lobster was seen by the Fishguard Diving Club. It was 5 feet long. A nice area to explore, tides are weak under the cliffs. The second small bay around from Martins Haven, heading east, there are some interesting gullies and small caves under the kelp at 8 meters. The area drops down to 20m, with a ridge running down from the bay seaward. The area of sand has a small Scallop bed. The area is protected, as it is in the Skomer reserve, and must not be touched. We have seen Sun Fish swimming along this point, and while I was watching them swim past the boat, they spotted the divers bubbles, diverted their path to decent down the bubbles! When the divers came up they said they saw two fins swim past them!! Here you will also get the chance of seeing octopus at about 15 metres. St Brides Bay. By boat. Use GPS to find High Point then dive the wall. High Point North is also known as St Brides Bay.
