ARGYLL & THE ISLES – THE BEST SPOTS FOR SCUBA DIVING IN SCOTLAND

SCUBA Diving is a popular specialist activity in the waters of Argyll & the Isles - and it’s easy to see why with some of the best SCUBA spots in Scotland. Think sheltered bays, glittering sea lochs and fascinating accessible wrecks. All just a stone’s throw from the hustle and bustle of Glasgow.

With 3,723KM of coastline, 32 inhabited islands and over 40 lochs, Argyll’s west coast waters are a SCUBA diver’s paradise. This is a very special marine area. Special because it has several international marine conservation designations and the UK's first Hope Spot. The Hope Spot is an area around the Sound of Jura, Firth of Lorn, Sound of Mull and Loch Linnhe which is teeming in biodiversity – explore serpulid reefs, kelp forests and wrecks that have formed artificial reefs.

The waters are (relatively!) warm from the Gulfstream and they are often crystal clear. There’s something for every diving enthusiast - gentle scenic dives, intriguing wreck explorations and challenging drift dives with strong tidal flows and deep drop offs. You can even enjoy blackwater and floodlit night diving.

Best SCUBA Diving Spots in Argyll

Local recommendations

Loch Fyne

The sheltered waters of Loch Fyne offer an abundance of wildlife. Spot colonies of anemones, different species of starfish, hermit crabs and moon jellyfish. Bob your head above the water and you are likely to see seals and possibly dolphins.

Loch Long

Dive next to the Finnart Oil Terminal on the eastern shore of Loch Long, about two miles north of Garelochhead, to see lots of different habitats created by the wreckage of the old pier. Look for sea orange sponge, sea cucumbers, plaice and peacock worms.

The Caves at Loch Long

With fabulous visibility and a complex underwater topography - with pinnacles close to the surface at low tide, Loch Long offers the opportunity to get up close to a rich variety of marine life.

Loch Creran 

Loch Creran, a few miles north of Oban, offers a good variety of interesting dive sites. Many of the dives are accessible from the shore and conditions are generally sheltered. Explore serpulid reefs and horse mussel beds.

The Firth of Lorn and Sound of Mull has many sites of interest, here are a some of the top spot;

1. Dunollie Castle

Close to the shore of Oban, you can drift dive around the coastline next to the ruins of Dunollie Castle and spot colourful Deadman’s Fingers and Sunstars.

2. Lochaline Pier and Calve Island

Calve Island is a spectacular cliff dive with stunning kelp beds providing a rich marine habitat. Lochaline Pier is a great wall dive, teeming with sea life. For divers bringing your own boats, there are plenty of launch sites. In addition, several dive boat operators run large hardboats taking up to 12 divers and smaller RIBs to the local dive sites.

3. The Garvellachs

The Garvellachs – the ‘rough islands’ – lie close to the shore of Oban and offer spectacular dives down rock faces and pinnacles. The area has very strong tidal currents which peak in Corryvreckan – the world’s third largest whirlpool. This is a dive that should only be attempted by the  fittest, most skilled, experienced and adventurous divers.

A little further south down the Kintyre peninsula, you can find more spots;

South Kintyre

The waters on the south coast of Kintyre of offer beautiful scenic and wreck dives. Most dives are relatively shallow (less then 20m) and much of the deeper waters have yet to be explored.

Penseorach Farm welcomes divers with a launch point for dive boats and a compressed air station.

SS Breda, Oban

A casualty of bombing in 1940, SS Breda is one of the largest and most intact coastal wrecks in Scotland. The site is suitable for all divers with easy dives along the flat deck and penetration dives for experienced divers. There’s always plenty of marine life and the site is perfect for photography.

SS Meldon, South Mull

This stunning and intriguing wreck site is home to the steel ship SS Meldon which ran aground after hitting a mine. This artificial reef is teeming with life - including a resident otter! It is depth accessible and has consistently good visibility. With a max depth of around 15m the site can be enjoyed by novice and experienced divers alike. At low water, the wreck breaches the surface making it suitable for snorkelling.

Other wreck site

The Argyll mainland and the surrounding area has lots of wrecks to explore, including Madam Alice, Thesis, Apollo, Rondo and Hispania.

A full list of wreck sites can be found here.

Visitors to the area are often interested in the wreck of the Flying Boats. This is an incredibly challenging site and likely to be a war grave so private dives are not encouraged.

Closer to Glasgow, there are 20 wrecks within half an hour’s boat trip of the Holy Loch near Dunoon.

Why try SCUBA diving?

SCUBA diving is not a sport that you can just try on holiday - you need to take lessons and become certified.

It’s worth it though. SCUBA diving opens up a whole new world of underwater wonder where you can get up close to the flora and fauna of the oceans. Some describe SCUBA diving as like visiting a colourful living museum.

SCUBA Diving is an incredible way to explore under the water but it’s not without risk. Sadly, there are diving fatalities every year in UK waters and even experienced divers can run into difficulties. Minimise the risks by following these snorkelling safety tips from the RNLI.

We strongly recommend reading the RNLI SCUBA Diving Safety Summary.

Safety first!

  • Be fit to dive - prepare yourself by being fit to dive – cold water will put extra strain on your body. Always consider your cardiac health before diving and get any concerns checked out.
  • Check your diving equipment at the start of the season make sure all your diving gear is in service and ready for another year’s diving.
  • Plan your dives - check the weather and tides.
  • Always complete a buddy check. No matter how experienced you are, or however many times you have dived with your buddy, don’t skip the buddy check. It could save your life, and theirs.
  • Be spotted. All divers should carry a surface marker buoy or delayed surface marker buoy on every dive to aid their visibility to all surface craft.
  • Carry a means of calling for help. If something goes wrong, how will you call for help? Consider carrying a personal locator beacon or similar device in a waterproof canister.
