Ask any diver to name the greatest wreck in the world and one name comes up again and again: the SS Thistlegorm. Rediscovered by Jacques Cousteau in the 1950s and reopened to sport divers decades later, she is a WWII time capsule resting on the seabed of the northern Red Sea — and she belongs on every serious diver’s list.

The story: a wartime cargo ship frozen in time

The Thistlegorm was a British armed merchant ship sunk by German bombers in October 1941 while carrying war supplies for the Allied forces in North Africa. She went down in minutes — and with her, an entire military cargo that still fills her holds today: motorcycles, trucks, rifles, aircraft parts, railway locomotives and stacks of Wellington boots. Diving her is less like visiting a wreck and more like swimming through a sunken museum.

Depth, conditions and certification

  • Depth: the deck sits around 16–18m; the seabed and stern reach 30–32m.
  • Certification: PADI Advanced Open Water is recommended; a Wreck or Deep specialty helps you get the most from her.
  • Current: can be strong — this is an open-water site, so good buoyancy and air control matter.
  • Best months: March–May and September–November for the calmest crossings.

What you will see

The famous motorcycle holds are the highlight — rows of BSA and Norton bikes still strapped in place. Outside, two steam locomotives lie where the explosion threw them, and the whole structure is now draped in soft coral and patrolled by batfish, jacks, barracuda and the occasional turtle. Penetration should only be attempted with proper training, lights and a guide.

How to dive the Thistlegorm from Hurghada in 2026

Because of her location near the Strait of Gubal, the Thistlegorm is usually dived on a full-day or overnight trip from Hurghada, or as part of a northern Red Sea liveaboard route. Day trips make an early start and are best for divers who already have a few boat dives and some experience with mild current.

Dive it respectfully

The Thistlegorm is both a dive site and a war grave — sailors died when she sank. Take nothing, break nothing, and avoid finning up silt inside the holds so the divers behind you can see her too.

How deep is the Thistlegorm?

The deck sits at around 16 to 18 metres and the seabed alongside the stern reaches 30 to 32 metres, so most of the wreck is inside recreational limits. A guided tour of the holds and the deck cargo happens between 18 and 24 metres; the propeller and the deepest sections are what take you towards 30. PADI Advanced Open Water is the practical level for it, and a Deep or Wreck specialty makes the deeper parts comfortable rather than rushed.

Do you need Advanced Open Water for the Thistlegorm?

It is the sensible level and what most operators ask for, because the dive is planned around depth, current and a long day on the water rather than around the shallowest possible route. A confident Open Water diver in good conditions can be looked after on the upper deck sections, but that is the centre's call on the day and not something to assume when you book. If the wreck is the reason you are coming, do Advanced Open Water first and dive it properly.
