From the cold waters of Scotland to the Great Barrier Reef lie the wrecks of once mighty warships.

There is something about a shipwreck that haunts the imagination. Maybe it's the horrifying thought of a ship going down and the loss of life entailed – or maybe it's the way once glorious vessels that sailed the oceans lie broken on the sea floor. Whatever the reason, they hold a magnetic appeal for adventurous divers and photographers. We pick some of the best to explore.

The best wreck for easy access

U.S.S. Kittiwake
Why: Shallow waters mean you can dive all day
Where: Cayman Islands

The ship is ideal for first time wreck explorers: Purpose sunk off Grand Cayman’s Seven Mile Beach in 2011, the 76.5m long Kittiwake was stripped clean of hazards before sinking. Doors and hatches were removed, giving each room at least one exit point.

Those with wreck diver certification cards can penetrate all five of the ship’s levels. The wheelhouse is shallowest, housing the wheel and compass. Two recompression chambers and the artificial diving bell are also highlights.

The world's largest wreck

S.S. President Coolidge
Why: Military gear, easy access, mapped routes all on offer
Where: Vanuatu

Consider the Coolidge like a ski resort. The 200m luxury-ocean-liner-turned-troop-ship has dozens of mapped routes ideal for beginners, intermediate and advanced divers. It’s the world’s largest wreck, and with beach access off the island of Espiritu Santo, Vanuatu, also among the most accessible.

Beginners should target the bow, a shallow pick at 20m. On the promenade at 33m, find rifles, gas masks and helmets. Warm up on these areas, and if you’re still not tapped out, guides can lead you on a penetration dive of the two cargo holds as well as the medical supply room.

Dive through a satellite dish

U.S.N.S. General Hoyt S. Vandenberg
Elevator shafts you can freefall into
Key West, Florida

For advanced divers, the thrill of the 158m 'Vandy' starts with a drop down one of the 11 elevator shafts, choosing any floor to enter. Those with less technical training can still freefall into the elevator and cargo shafts of this Air Force missile-tracking ship off the coast of Key West, Florida.

Downed in 2009, this artificial reef has been cleaned of hazards, and made safer with doors removed and blowtorch-added exit points. Unique to the ship are the 2m resident goliath grouper and the ship’s satellite dishes that divers pop out of following swims through the interior. Oh, and the vessel served as a set for the sci-fi flick Virus – hence the Russian lettering in the passageways.

Best wreck for cold water fans

S.M.S. Coln
Why: The sense of history
Where: Scotland

“If you don’t enjoy the cold, it’s probably time for another pastime,” says Scapa Scuba dive shop instructor Kieran Hatton of the brisk waters surrounding the Scapa Flow wrecks off the Orkney Islands of Northern Scotland. Scapa Flow is the graveyard of the WW1 German Navy, which was scuttled in 1919.

His top pick for an intact vessel is the 155m-long S.M.S Coln, a German cruiser now on its starboard side in 36m of water.
Why go? “You’ll see the graceful lines of an early 20th century warship,” he says, “Plus a few guns are still in place – these things are as big as your arm.”

Best wreck for sea life

S.S. Yongala
Varied fish life make it a fascinating dive

Eagle rays lay in stacks on the deck of the S.S. Yongala. Giant Queensland grouper patrol the stern. Sea snakes, turtles and clownfish also congregate on this 358-foot steamship downed by a 1911 cyclone in what is now Australia’s Great Barrier Reef Marine Park. Find it 12 nautical miles off Cape Bowling Green, Queensland. Thanks to its depth of 28m and the likelihood of a current – which helps attract schools of trevally – it is an advanced dive.

Best wreck for vintage motorcycle fans

S.S. Thistlegorm
: This merchant ship is still loaded with WW2 booty
Where: Egypt

Not for the claustrophobic, this wreck offers room after underwater room of war supplies. In 1941, two bombs sunk this British armed Merchant Navy ship in the Red Sea near Sharm el-Sheikh, Egypt. It’s a true wartime wreck still holding most of her cargo.

Divers thread overtop Bedford trucks and a fleet of Norton 16H motorcycles, keeping buoyancy so as not to brush against the rooms’ ceilings, now painted with divers’ exhaust bubbles trapped as mirror-like puddles. It’s a dive that can be as mentally taxing as it is physical: The wreck lies at a depth of 30m and the stern is tilted on its port side, making disorientation likely.

Best wreck for WW2 supplies

San Francisco Maru
Vintage tanks and rich sea life

Sometimes known as the 'million dollar' wreck, the San Francisco Maru was sunk in Eten Anchorage in 1944 while carrying a payload of tanks, trucks, mines and bombs. The wreck was discovered in 1969 by legendary French frogman Jacques Cousteau and since then it's proved a popular wreck to dive.

One of her most striking features are the three Japanese Type-95 light tanks that still remain on her deck. Elsewhere are mines and torpedos. Just don't touch anything!

The best wreck for non-divers

Eduard Bohlen
Haunting reminder of the sea's power

Don't be fooled. Just because you don't have to dive doesn't make this an easy wreck to access. Says photographer Christian Ghammachi: “It is nearly impossible to reach and people usually can only fly above it. You need a license to get there and a guide in a special vehicle.”

The wreck ran aground in thick fog just south of Namibia's Skeleton coast, an infamous ships' graveyard, in 1909. It now lies about 800m inland, where the desert has encroached on the sea, a haunting reminder of man's vulnerability to the ocean.
