Hard boat from Isles of Scilly

Trenemene Reef is also known as Trenemene Wall Isles of Scilly.

Trenemene Reef

The Cita sank in September 1996, it was bound from Southampton to Belfast, but didn't turn right as it got past the Lizzard in Cornwall and piled up on St Marys in the Scillies. For a couple of weeks it was hung up on the rocks, but gradually slipped back and now the bows remain shallow, but the stern has settled back to 40m



Cita

Bread & Butter cove is a site to do when all else are blown out, but it certainly isn't second best. It teems with interesting sea life on the boulders scattered over the sandy seabed

Access to the Scillies is the first challenge!
By air (helicopter or light aircraft) means you are limited as to the kit you can take with you.
By Sea, The Scillonian III will get you there.

Once in the Scillies, there are a couple of commercial dive operations, or you could always take your own boat. Tides & cuuents here require a great deal of local knowledge! 

Bread & Butter Cove

Good shore dive, swim south from entry point for about 200 meters. Staying west of the extensive eel grass at approx 5 metres depth on low tide or about 9 metres on a high tide. When  you come across an old iron ships bollard approx 60cm high. Wreck then 20 meters east from this point. Highlights include wrasse, cuttlefish, lightbulb sea squirts, spiny spidercrab, dragonnettes, spiny star fish, pollack, southern cup coral, devonshire cup coral, sponges, anemones, nudibranch egg casings.

Access from the road through opening in fence, down step dirt track and rocks to the beach.

Roskilly

Several gullies lie on the seaward side of Mullion Island, depths ranging from 10 to 18 metres. Lots of kelp and plant life, as well as a mixture of fish and smaller life. A cannon can apparently be found in one of the deeper gullies.

By boat from one of the nearby launch sites. Closest access is Mullion harbour itself.

Mullion Island

A shallow kelp forest around the rocks near Mullion harbour. Fast currents flow in the shallow areas between rocks, so best to dive on the seaward side of the largest rock, following its wall and the kelp as a rough guide. Starfish and crabs can be found on the bottom, as well as the occasional lobster in the cracks in the rock.

Enter the water by the steps at Mullion harbour, then a short swim to the site. Best to stay on the surface near the harbour, due to fishing lines.

Mullion Cove

Use Porthkerris Divers boats to get you on this site. Best dived on an incoming tide, drift up the river mouth with the current, Dogfish, Thornback Rays, Sea Hares and loads of stuff everywhere. Brilliant!!!!!!!!
Do not take any scallops, the Helford River is a private fishery, taking scallops is theft.

Accessed by boats from Falmouth or Porthkerris.

Helford River

A separate dive used mostly for training on the flat stony bottom. Can be dived independently or on the way back to the beach from a dive at Drawna Rock. Kelp grows on the right of the site near the rocks. This area can be explored at the end of a training dive to look for starfish and sea urchins. 

Porthkerris. Easy entry via the stoney beach. Entrance to the site cost per diver.

Porthkerris Fish Bowl

A shallow kelp forest starts just out from the concrete structure and carries on round the rocks to the north. Lots of seabed life including various species of starfish and spider crabs. DSMB's should be used due to boat traffic during the week.

Easy entry from the stoney beach. Parking is allowed on the beach, so you can kit up very near the site. Keep to the north (left) side of the bay due to boat traffic.

Porthoustock

The seaward side of Drawna Rock contains the deepest part of the site, reaching to 18 metres at high tide. A kelp reef with good walls and cracks to explore in the rocks. When the current is strong, you can drift between the two rocks and swim back on the seaward side. Lots of life including wrasse and starfish.

Enter by the beach or from a boat for a second dive. Charges per diver apply to use the beach. Air can be filled on site.

Drawna Rock is also known as Porthkerris.

Drawna Rock

The wreck can actually be seen in the Google maps image above, at low tide you can walk around it. A bit of a swim but very interesting once you're there. A 422 ton fishing trawler that came ashore in the 1970's.

Maenporth beach is at the southern end of Falmouths beaches. Car park is on the beach. Enter on the north side and follow the reef. It is a long swim out to the wreck, in fairly shallow water but it is an easy dive.

Maenporth Beach is also known as Ben Asdale.
