SS Thistlegorm Wreck Dive: Everything You Need to Know

The SS Thistlegorm is among the most visited wreck dives on the planet. Consistently cited alongside Truk Lagoon, Bikini Atoll, and the USAT Liberty in Bali as one of the world’s great wreck dives, it offers something that few other sites can: an intact wartime cargo manifest, perfectly preserved at depth, accessible to recreational divers with Advanced Open Water certification. Here is what you need to know before you go.

The Ship’s History

The SS Thistlegorm was a British armed merchant vessel built in 1940 in Sunderland, England. She was 126 metres long, 17 metres wide, and launched into war service immediately after her commissioning. In October 1941, she was moored in the Sha’ab Ali area of the northern Red Sea, waiting for the Suez Canal to reopen. She was carrying a substantial military cargo destined for British troops in North Africa.

On the night of 6 October 1941, two German Heinkel He 111 bombers located the Thistlegorm using intelligence from a captured convoy manifest. The planes dropped bombs directly onto the aft cargo holds, detonating the ammunition stored there. The explosion was catastrophic - witnesses reported it was visible from 15 kilometres away. Four crew members and five soldiers died. The ship sank in minutes, settling on the sandy bottom at approximately 30 metres.

Jacques Cousteau discovered the wreck in 1955, but it remained relatively unknown until the 1990s when Sharm el-Sheikh’s dive industry expanded and operators began running regular trips. Today, it is one of the most dived wrecks in the world.

What You’ll See on the Dive

The Thistlegorm’s cargo holds are the main attraction, and they are extraordinary. The aft sections were destroyed in the explosion, but the forward holds are largely intact and accessible. Inside you will find:

Hold 4 (the most photographed section): BSA WM20 military motorcycles, still upright on their stands or lying where they fell during the blast. Several dozen bikes, in varying states of corrosion but still distinctly motorcycle-shaped. This is one of the more surreal images in Red Sea diving.

Hold 3: Bedford trucks and armoured vehicles. Some remain on the deck; others have slid sideways in the hold. The scale of the vehicles relative to the space is impressive.

Hold 2: Lee-Enfield rifles, ammunition boxes, rubber Wellington boots, aircraft parts, and radio equipment. The rifles have been much photographed and have been left largely as they fell in 1941.

Hold 1 (the locomotive hold): Two intact railway locomotives are visible here, along with rail bogies. The locomotives were too large for the holds and were loaded as deck cargo; the explosion sent them over the side and they now rest near the hull of the ship.

The superstructure: The ship’s bridge, gun platforms, telegraph, and various crew areas are all accessible. The 4-inch deck gun on the stern is still in position. Corals, sponges, and lionfish have colonised virtually every surface.

Marine life on and around the wreck is excellent year-round: batfish, glassfish, lionfish, jack, and moray eels are all residents. The structural complexity of the wreck creates a wide variety of micro-habitats.

Certification Requirements

Advanced Open Water (AOW) or equivalent is the minimum certification. The wreck sits at 28–30 metres - the depth limit of AOW and beyond the reach of Open Water divers (maximum 18 metres). Most reputable Sharm el-Sheikh operators will not take Open Water divers to the site.

If you don’t yet have AOW, Dahab is the cheapest place to complete it (see our learn to dive in Dahab guide). An AOW course in Dahab runs approximately €200–250 as of 2026 and takes two days.

Dive computers are strongly recommended - you’ll hit your no-decompression limits faster at 30 metres than at shallower recreational sites, and monitoring bottom time carefully matters here.

Day Trip vs Liveaboard

Day Trip from Sharm el-Sheikh

The most common way to dive the Thistlegorm. Boats depart from Sharm’s main marina at around 6–7am and typically take 2 hours to reach the site. Most day trips include two dives on the wreck. Lunch is served on the boat between dives. Return to Sharm by late afternoon.

Cost: Approximately $80–120 USD per person as of 2026, including equipment rental, tanks, and lunch. Some operators charge separately for equipment if you bring your own.

Drawback: Day-trip boats all arrive at the site at roughly the same time, which means significant boat and diver traffic between 10am and 2pm. Visibility can be affected and the experience is more crowded than it might otherwise be. Arrive on the first boat possible for the quietest conditions.

Liveaboard from Sharm or Hurghada

A liveaboard gives you the option of an early-morning dive on the Thistlegorm before the day-trip boats arrive. The difference in experience is significant - diving a World War II cargo hold with three other divers rather than forty is an entirely different proposition. Most Northern Route liveaboards include the Thistlegorm as a standard stop.

Cost: Liveaboard packages including the Thistlegorm as part of a broader Northern Route itinerary run approximately $1,200–1,500 for 5–7 nights as of 2026. Premium operators charge $2,000–2,500. See our liveaboard diving guide for operator recommendations and booking advice.

Advantage: Early access to the site, multiple dives possible, and the full Red Sea liveaboard experience alongside the Thistlegorm.

Practical Details

Getting to Sharm el-Sheikh: Fly direct from major European hubs (London, Frankfurt, Vienna, Warsaw) or connect via Cairo. Sharm International Airport is 15km from the dive centres.

Where to book: Marine Sport is one of the more established day-trip operators in Sharm. Emperor Divers (emperordivers.com), Colona Watersports, and Camel Dive Club all run regular Thistlegorm trips with solid safety records. GetYourGuide also lists vetted Thistlegorm day trips with verified reviews and upfront pricing. Check PADI status before booking and confirm whether equipment is included in the quoted price.

Nitrox: Available at most Sharm dive centres and strongly recommended for Thistlegorm diving. Nitrox extends your no-decompression bottom time at 30 metres and allows more time inside the cargo holds. Bring your nitrox certification if you have it.

What to bring: Dive computer (don’t rely on a borrowed one at 30m), torch or dive light for the holds (the cargo holds are dark inside the ship), and a surface marker buoy (SMB) for ascents.

Best season: October to May. The Thistlegorm is diveable year-round, but the summer months (June–August) bring peak boat traffic at the site. Winter months offer slightly cooler water (22–24°C) but clearer conditions and fewer boats.
