Located approximately 800m southwest of the Dingle Harbour entrance the Crow Rock provides a comprehensive range of diving in calm southwesterlies or strong northerlies. It is generally clearly visible being awash through all but the highest spring tides. The north face of the rock has a ledge at 15m sloping down to sand at 20m. A colourful 15–20m dive is available moving west from the rock while the south face slopes down rapidly to boulders at 35 m.

As a strong westerly wind will make most dives around the Blaskets and the peninsula uncomfortable your only escape may be Smerwick Harbour on the north coast. Launching from Wine Strand, interesting shallow dives, maximum depth 15m, may be made along the western side of the harbour. If you need to log deep dives then you can generally get whatever depth you require in the middle of the bay, on sand. The further out you go, the deeper it gets. Outside the harbour to the southwest under the Three Sisters and Sybil Head there is excellent wall diving.

The second Great Blasket wreck is a WWI munitions ship which sank on the north face. The “Quiebra” lies in 15–27m of water starting in a gully just off a rock known as “Speir Cuas Faill Beag”. This wreck is well broken up but as the dive site is relatively sheltered from most winds it offers a good, safe and interesting dive. The cargo consisted of wire and artillery shells and these can be seen in the gullies to the west of the wreck. On the wreck the boilers are standing upright while the recoil spring of a ship’s gun is still to be seen. Heading north out into deeper water (30m+) the gully, containing the main bulk of the wreck, falls away.

This island has excellent diving and large schools of fish especially beneath the lighthouse (the most westerly lighthouse in Europe) and along the ridges and gullies of the north face. There are two landing stages to serve the lighthouse on the north, and south of the spectacular sea arch and it is possible to get ashore there from inflatables.

One of two good wrecks lying off the Great Blasket Island this is a 30m steel fishing boat lying between 18–30m near the southwest point of the island. The hull is sound and clean and so provides an excellent introduction to wreck diving to the uninitiated. The exact position of this wreck is not known, to the writer, so local knowledge is required to find it.

Twelve kilometres from Dingle on the north of the peninsula Brandon Creek provides excellent diving in strong southerly winds. It is a beautiful cove with a reasonable slip and pier which is usable 2 hours after low water. Just at the head of the creek on the west side there is a sea arch which provides lovely snorkelling and leads down to a 18m dive towards the centre of the creek. Moving either east or west out of the cove there is excellent wall diving with the bottom generally starting at 30m and dropping away deeper very quickly. Visibility in settled conditions is generally 20m plus and marine life is plentiful and varied.

The most northerly island has excellent diving on the easterly face (drop off from 15–40m) and in the cove on south west face 15–20m with nice gullies and lots of life including seals.
At the most northerly tip of this rocky pinnacle there is a most spectacular dive. Starting at the tip (during slack water as there are rip tides in this area) and heading in a southwesterly direction with the reef to the right you will descend to 15m, maintaining this direction you come after a few metres, to the top of a wall which is covered in jewel anemones, sponges, cracks and crevices for crabs and crayfish.
The maximum depth here is approx. 40m. Following this wall the direction swings more NW and you enter a gully which eventually narrows into an undersea cave. With the aid of a torch one can follow this cave for a short distance to find it blocked by a boulder. Keeping the reef wall to your right, the gully begins to open at about 20m. Here there is a series of outcrops and ledges with plenty of life. The general direction of the dive is SW and these ledges and small gullies fade away into a flatter but craggier terrain. In general this is a terrific dive site, with good shelter from most winds, and a range of depths making it suitable for all types of divers.

Just off the slip and out of the small natural harbour of the Great Blasket, the area has a maximum depth of 12m and is suitable for trainees. Heading east out of the harbour you can follow the reef which acts as a breakwater for the slipway. The bottom is on white sand with a wide variety of sea life and the reef is frequented by seals. Returning along the original dive path instead of reentering the harbour proper head northwest across the sands to another group of rocks and some shallow gullies. This is an excellent shore dive for the trainee or casual pottering diver. During the day it is advisable to use an SMB as the ferry boats operating to and from the island have to travel over this dive site in order to reach the slipway.

This most southerly island is privately owned but has excellent diving along its south shore, most notably at Fohish Rocks. There are three pinnacles joined by a reef with a ledge out 20m on the northeast side but dropping rapidly to 40m. Fish life is abundant with plenty of drop off.
