Local Dive Sites

This page contains some of the incredible places we take divers to - we are frequently updating adding new information and sites.

Be aware that currents can be very strong and local knowledge is essential to dive many of the sites listed here. The prevailing winds are south westerly and we tend to dive the North Pembrokeshire coast on weekends. If we get strong northerlies or we plan to dive the southerly limits of our range we either take Wandrin' Star down to south of the St.Davids Cape or trailer JanHazel down and launch from Porth Clais.

Our range from the north is Aberporth, Cardigan Bay, Newport Bay, Dinas, Fishguard Bay, Strumble Head south down to St Davids Head, Ramsey, Bishops and Clerks, Grassholm, St. Brides Bay, Skomer, Skokholm and out to The Smalls in the south west. We load Wandrin' Star at Fishguard and are able to moor up at Porth Gain or Porth Lyski to minimise steaming times on week long bookings.

We will always do our best to get you the diving you would like but there are often variables such as the weather, tides and swell that will have an effect on the conditions and where we decide it is appropriate to dive.

HMS Whirlwind, Aberporth

Second World War Royal Navy Hunter Class Destroyer, she saw action in the air strikes on Medan, Palembang and Sumatra, in the bombardment of the Sakashima group, in the reoccupation of Hong Kong and in the landings on Okinawa.

The Sutton - Mynt

The tragic Liverpool steamer "Sutton" which sank on her maiden voyage after leaving
Aberystwyth bound for Antwerp with a cargo of mineral concentrates.
Sunk 29th November 1925 with the loss of fourteen lives.

She lies at a depth of 30 mts or so, broken but recognisable, the seabed reflects light and visibility can be very good. The wreckage is populated with dead mans fingers, anenomies, lobsters, congers and shoals of fish - a very nice no stop dive.

We took John Liddiard to this site if you would like to view some of the stunning photos he took please click here.

Mark on Sutton

The Herefordshire - Cardigan Island

She was built in 1905 by Harland & Wolff at Belfast with a tonnage of 7182grt, a length of 452ft 4in, a beam of 54ft 4in and a service speed of 15 knots. Sister of the Worcestershire she was launched on 31st August 1905 and completed on 29th November.

On the outbreak of the First World War in 1914 Bibby Line's seven well-equipped steamers were all requisitioned by the Government. She remained on the Burma run until 25th July 1916 when she was requisitioned as a hospital ship for 380 patients serving Salonika, Mesopotamia and East Africa.

On 1st January 1918 she was decommissioned and on 4th February was narrowly missed by two torpedoes during her first Mediterranean convoy. When the torpedo tracks were spotted her Master, Capt.G. E. Millson, ordered the helm hard over and one engine to full astern which slewed the ship around. One torpedo passed under the counter stern missing by a foot or so and one of the torpedoes went on to hit P&O's Sardinia.

In 1920 she was refitted by her builder and converted to oil burning. She was rebuilt for cargo services only in 1929 and equipped with, in addition to modifications for transiting the Manchester Ship Canal, a heavy lift derrick on the foremast.

In April 1933 she was laid up at Dartmouth and on 9th March 1934 left in tow bound for Clyde shipbreakers. On 15th March she grounded on Cardigan Island and was a total loss.

The wreck is well broken up but large parts, boilers, turbines and girders scattered lying at about 15 mts, plenty of life and nice topography.

William Rhodes Moorhouse
- Fishguard

Milford registered trawler (ex-Naval MFV) left Milford Easter Saturday 1968 for Cardigan Bay fishing grounds. Trawl winch developed fault on Easter Monday - April 15th – and fishing gear could not be fully hauled up. That evening the fish-hold started to flood. Six man crew took to life-raft and were rescued by an oil tanker (Esso Purfleet) and then transferred to Fishguard Lifeboat. Lifeboat attempted towing vessel but she listed and tow-line had to be released - A smallish wreck at about 30 mts, lots of life, plenty to look at - a nice no stop dive.

Divers interested in visiting this site must have proof of recent deep/ technical diving experience and qualifications.


Carregwasted Bay

Site of the last French invasion 1797 - Kelp and rocks; great place for seal encounters...


A wooden sailing ship, sank in a force 9 gale off Strumble Head. A rescue was attempted over the cliffs, but the ship broke up within minutes and the crew were lost.

She lies at between 4-11 meters, there are a few wooden beams scattered and angle irons - a very pretty dive site with interesting topography and wildlife.



Calburga - Strumble Head

She was the last of the square rigged sailing ships to be lost in this area - 1,406 tons, length 210 feet, beam 39. She was hit by a hurricane which blew out her sails and downed three of her masts. She finally hit the cliffs and sank in deep waters.

She lies at 43m, the wreckage covers a large area, there is a drop off to a stoney bottom, there you can find the pins and make your way to a crevice that brings you up to a huge anchor that looks like it has been stuck to the side of the wall ! - depths from 10 to 40 meters. Dogfish, wrasse, lobsters, crabs, octopus...

Strumble Head rated as number 7 out of Britain's 20 biggest wall dives !

From Larn's "Shipwreck Index" -

"At 13.55 on 10 Dec. 1944 a single torpedo fired by the U-2102 struck the port side of the Liberty ship level with number 9 hold, causing her to break in two immediately. The survivors abandoned ship in two lifeboats and one liferaft, a third lifeboat capsizing whilst being launched, a fourth swamped. The last to leave the vessel were the master and the armed guard commander, both men jumped overboard and were picked up by no. 2 lifeboat. Distress flares sighted by Strumble Head Coastguard saw the Fishguard lifeboat launched at 6 p.m. but on reaching the wreck found it surrounded by oil and abandoned. One of the lifeboat crew was taken ill and the boat turned back for Fishguard where the man was transferred to a police car, but on reaching home died. One of the ships lifeboats with 23 survivors reached the shore safely, whilst a liferaft with 13 men on board was picked up by Fishguard lifeboat, one of survivors who was seriously injured died before they reached the lifeboat station. The bow section drifted ashore 2.5 miles south of Strumble Head"

The Dan Beard was a US Liberty Ship that had seen action during the D Day landings. Her bow now lies about 14 mts, the wreckage is well broken up and scattered amongst boulders. There is a cave nearby in which a mast is lying and very often there are seals present.

We are still searching for the stern section which we believe lies much further away in deeper water.

Who was Dan Beard ? To find out: click here




Charles Holmes - Abermawr Bay

886 ton sailing vessel - sank in 1859 She hit a rock in a terrible storm and scattered her cargo - thousands of pieces of pottery. Allegedly a chest of gold was on board which has to this day not been recovered. The pottery pieces are still being picked up today. Very broken up and scattered. The bodies of the crew were washed ashore and are buried in the local church yard.


Bola Bleiddyn - Abercastle

Reef that rises up from 22 meters to 8 meters, lots of dogfish, pollack, dead mans' fingers and we spotted the daddy of all crayfish !!

Abercastle Blow Hole

An underwater cave, which extends into the cliffs 8m or so and ending at a small blow hole.

Leysian - Abercastle

Depth 15m - Lots of wreckage, that attracts a variety of fish, a safe, interesting and relatively easy wreck dive with plenty of features.

Abercastle Reef

Fantastic reef full of life depth down to 22 meters.

Baron Ardrossan - Porth Gain

Steamship sunk 1898 - Weight 1451 tons, length 243 feet beam 34 feet. She ran into thick sea fog carrying a cargo of coal, but on a wrong heading.

Depths 10m to 13m - Boiler intact, prop still there, lots of wreckage.

Traeth Rock

A rock rising from 25m to 6m. Out from Aberieddy beach.

The Tower Off Abereiddi Beach

A large pinnacle of rock.

The Sledges

A group of large rocks, off Aberieddy beach, still a danger to shipping today.





SS Musgrave

Wreck Tour 123 April 2009 issue of Diver Magazine - Click Here to read the feature

Steamship sunk 1892. Depth 28m to 32m, fairly intact but broken in two parts, lying upside down, rudder, prop, boiler with conger eels, blennies and dab.

For more info on the Musgrave and our wreck dive sites please click to read John Liddiard's feature Legends in Their Own Lunchbox or The Pride of Pembrokeshire



Laden with 1,885 tons of coal and bound for Italy, she hit the outer sledge off Abereiddy in February 1886 after her Captain mistook the South Bishop lighthouse for a light off the Irish coast. All the crew reached safety without injury.

The steamer had run over the rock with such a force that she ended up straddled across it.  The swell soon broke her back and the stern section ended up on the seabed where it remains to this day. 

The depth is from 14mts to 18mts, there are a number of interesting features, including the engines, prop shaft and machinery. As this site is a large offshore rock, divers get the best of both worlds, a wreck on a reef !

Monkey Rocks

Lots of gullies, scallops, depths at around 20m. Also a good drift dive.


St Davids Head : Cargo Steamship built 1879 in Southampton. Hull material: Iron. Size: 1791 tonnes - Length: 88 m - Beam: 10 m
Sunk: 15/4/1881 Cause: Hit Rocks in Fog. Lies in 16 m upright. Orientation: bow to E - Condition: extensive breakup - Seabed: gravel

This wreck is well broken up but makes a good shallow second dive. There are bits of cargo still recognisable including some large iron wheels stacked together.

The Frederick - AKA The Musket Wreck

There is not much left of this shipwreck apart from the cargo, a huge lump of metal that was probably a load of swords. She has been named "The Musket Wreck" due to divers previously recovering whole flinlocks and parts. There are great gullies at this site that are full of life and if you look very carefully at about 20 mts you can still find small trading beads that the seabed will give up from time to time.



Nimrod - St. Davids Head

A Paddle Steamer from Ireland, 583 tons, length 177 feet, beam 25 feet. Sank in 1860 off St David's Head in depths of between 18m and 32m. Forty five people died, unable to climb the cliffs to safety.
The Captain had previously declined help from a passing ship.

The wreck is in three parts, her anchor lies at 20m and the chain leads down to 30m.
The middle section is nearby at 35m - Two boilers are still standing.

We know very little about this shipwreck and the name is still speculative. Originally we thought that she was a small vessel lying in a gulley, but after more exploration we have found that in fact she was actually much larger and appears to have collapsed into a series of gullies over the years.

We have found two boilers and engines, but no prop shaft and this leads us to believe that she may well have been a paddle steamer.

The George - Porth Lyski

Steamer, boiler still intact, wrasse and conger in residence.

Pie Gulley - Solva

Depth down to 20m, anenomies, starfish, tubeworms, fans, nudibranchs, absolutely teeming with life.

Green Scar - Solva

Depth 18m. Bits of steamship wreckage are scattered on the bottom, a boiler sticks out from the sand, chain runs across to an anchor.

Black Scar - Solva

Small reef with plenty of life - seals often bask in the sun on the exposed rocks.

Reef Solva

SW of Green Scar, runs north to south. Large gullies to 20 metes Plenty of life; dog fish, sea cucumbers.


Edible Crab


Home to a variety of wild life; Grey Seal, Puffins, Razorbills, Choughs, Guillemots, Kittiwakes, Fulmars, Gulls, Dolphins and Porpoise.

The Island and surroundings are a Marine National Park and nothing is to be taken from the sea bed. The North Wall and Rye Rocks are just two of the sites thet we like to dive here.

The Lucy

Wreck Tour 3 Diver Magazine - Click Here to read John Liddiard's feature

The most famous shipwreck of Wales has to be the 450-ton two-hold Dutch coaster Lucy. 168ft long she sank in 1967 with a cargo of calcium carbide. Having struck Cable Rock in the middle of Jack Sound on Valentine's Day, the 7-man crew and one Collie dog promptly abandoned ship to avoid the results of the sea water mixing with calcium carbide.

She remained fairly well balanced on the reef until the early evening when the full tide lifted her off. The last sighting of her was that she was off through Jack sound heading North into St Brides Bay with a heavy list to starboard. She was never seen again, on the surface that is!! The current carried her into the entrance to North Haven where she sank perfectly upright in 40m of water.

Divers interested in visiting this site must have proof of recent deep diving experience and qualifications.



By special arrangement. We can take divers close to this incredible island.
11 nautical miles offshore, get mobbed by seals, dive bombed by gannets and escorted by porpoise !

There are 3 Shipwrecks: Dalserf - 26m, Mersey - 10m and Walter LM Russ - 10m

Weather conditions and tides have to be correct - we can only dive this site on certain dates please discuss with us prior to booking


The Smalls

The Smalls are famous for the marine life, including a large colony of seals. Visibility can be up to 25 metres.

There are a number of shipwrecks here but these are fairly well broken up and eclipsed by the fantastastic topography and underwater life that can be observed.

The Smalls are also a great spot for seeing dolphins and catching tasty mackerel !
