#9 - Dorothea Quarry
UK, Wales, Mid Wales

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.
#10 - Puffin Island
UK, Wales, North Wales
beginner
(0)
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.
#11 - Vivian Quarry
UK, Wales, North Wales
beginner

A small quarry that has lots of places for training. A platform at 6m and various bits of things to play with including an old boat.
Park in the large car park at the Padarn lake railway station. Llanberis.
#12 - Trefor Pier
UK, Wales, North Wales
beginner
(0)
Lots of life around the legs of the pier. Easy access from the shore. If you don;t mind a surface swim and the water is choppy the best access if via the harbour steps. Also beware of fishing lines even though officially closed the life under the pier still attracts a lot of attention at weekends.
Park directly at the start of the pier.

Although fairly flat and sandy, just north of the slipway are plenty of rocks usually full of crustatians.
Use slipway at and of promanade.
#14 - Menai Straits
UK, Wales, North Wales
intermediate
(0)
A rollercoaster! If doing by boat, go up past the swillies then drop in for the ride of your life. Best to keep the dive boat close to your marker bouy, as most weekend boaters haven't a clue what it means!
Either by boat or down the slipway under Menai bridge.
#15 - Blue lake
UK, Wales, Mid Wales
beginner
(0)
Although touted as "Bottomless" it has a maximum of 12m. The blueness is due to the slate that is sliding down from the far side. Entry can be either giant stride from the cliff edge or a gentle slope from the far right of footpath.
Not easy! By road you have o come in from Llwyngril across the top road then drop down to the lake from here. Defenatly 4 wheel drive territory. Otherwise it is a long walk up a steep path opposite Salt's garage in Fairbourne. Entry is then through tunnels following the old quarry rail track.
#16 - Ynys Moelfre
UK, Wales, North Wales

Must be dived on slack water to avoid the currents. lots of life on the rocks and plenty to see. watch out for the lobster pots and please don't steal from them as the local fishermen will report you and take revenge.

Depending on the state of the tide, the keel of the small 471 ton sand dredger Hoveringham does break the surface, though with the 7m tidal range of the Menai Straits it also disappears a few metres below at high water. It is sheltered, shallow, colourful and intact. On the minus side, there are the currents of the Menai Straits with which to contend.
Penmore Point. Partially dries out at low tide.

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.

#23 - Blue Lagoon
UK, Wales, North Wales
beginner
(0)
An old slate quarry. Crystal clear blue water hence the name. A bit of a walk up a hill and you wouldn't think of diving it if you weren't looking for it but a nice dive nonetheless. Personally I use a trolley to drag the cylinder up on. Certainly worth doing.
Blue Lagoon is also known as Clogau Quarry.
#24 - North Stack
UK, Wales, North Wales
beginner
(0)
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.
#25 - The Flint Wreck
UK, Wales, North Wales

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.
#26 - High Point North
UK, Wales, South West Wales
beginner
(0)
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.

Two small walls, one on the left and another one on the right. Martins Haven is really a cool place, both for shore divig and picnic with familly & kids.
Take the B4327 from Haverfordwest towards Dale. Turn off for Marloes and go through the village. Turn left for Martin's Haven.
Use the car park 200m before the beach.
