Dive Sites

Lundy has numerous dive sites, further details can be found in ‘A Guide to Lundy’s Marine Wildlife’ Below are details of two of the most popular sites.

In June 2014, the Iona II Dive Trail was released including a Marine Life Trail for information please click here: Iona II Dive Trail

Knoll Pins

The Knoll pins are located on the eastern side of the island, between tibbetts point and Brazen Ward, approximately 200 metres east from Threequarter Wall Bay. NB -Please note anchoring restrictions apply, referto the Code of Conduct.

The name refers to a pair of large rocks that dry out at low water. When the Knoll Pins are submerged at high water the kelp on top of the Pins may be visible, but care should be exercised when approaching the area by boat. The Knoll Pins is a spectacular dive.

This dive starts on the southern side of the outer Pin, which should be kept on the left-hand side during descent. There is a drop off here, down to about 15 metres, and following the pinnacle wall down will reveal a sandy slope. Continuing down this slope whilst keeping the pinnacle on the left will mean travelling in an anticlockwise direction.

On the eastern face, the base of the pinnacle is at about 25 metres at its deepest. Here, the rock side of the pinnacle is near vertical. This is the most exposed part and tidal currents may be present. Around the pinnacle, the sand seabed slopes steeply up its northern side.

It is possible for divers to choose their depth on this dive and then spend time exploring the south, east and northern sides of the pinnacle. A good dive profile can be obtained here by slowly working back up towards the surface. The vertical exposed walls are covered in colourful jewel anemones. Cup corals are present, as are dead men’s fingers, red sea fingers, pink sea fans and sponges. There are also spider and edible crabs, lobsters and squat lobsters. Fish can include pollack, and wrasse may be seen cruising around the pinnacle, whilst shoals of sand eels dart over the adjacent sandy slope.

The seabed surrounding the pinnacle consists of sandy mud. As an alternative to staying on the pinnacle, it can be left and a tidal drift carried out over this mud. Creatures found on this seabed are similar to those off Brazen Ward. (See ‘A Guide to Lundy’s Marine Wildlife') The Knoll Pins should be dived during, just before, or just after, slack water.

MV Robert

The MV Robert was a small, single screw coaster which capsized and sank off the eastern side of Lundy in 1975.

The wreck lies approximately one mile east of Gull Rock and is usually marked by a buoy, which is attached to it. This is Lundy’s only intact wreck, and the 50 metre long vessel now rests on a muddy sand seabed on her starboard side. The port side of the ship is in about 18 metres of water, whilst the starboard lies on the seabed in about 25 metres. The bow section consists of the superstructure and accommodation.

The mid and forward section is a large open hold area.

The buoy line, usually attached to the bow of the Robert, on the anchor winch, is ideal for the descent onto the wreck. From the bow it is possible to enter the hold, which is wide and open, but dark. A torch is essential in order to have a good look around, especially on the inside of the port side of the hull where there are lots of small compartments, housing a variety of creatures. Inside the hold, head towards the stern and then drop down, still inside, and work forward. Keep clear of the mud floor (to avoid kicking up lots of sediment and reducing the visibility). Then exit the hold at the bow to briefly explore the bow section.

From here, go under the bow and move along the seabed next to the bottom of the ship, to her stern. Here, there are some sand dwelling creatures, including hermit and swimming crabs, scallops and burrowing anemones.

After looking around the stern, swim to the topside of the ship to explore the outside of the accommodation area. It is strongly recommended not to penetrate the accommodation, as entrances are narrow and the rooms very silty. The pipe work around this section usually houses conger eels. On the prominent parts of the ship, there is a profusion of white plumose anemones. There is often a small shoal of bib on the wreck and occasionally individual John Dory can be seen. There are usually a number of sea slugs on the outside of the hull.

Proceed to the outside of the port bow and then to the bow section, where the buoy line is tethered, for the ascent. This dive should only be carried out during slack water as the tidal stream can be very strong over the wreck.

Depths given are approximate depths for low water.
