Thistlegorm is the classic Red Sea wreck dive: a famous WWII cargo ship that rewards advanced divers with a long boat approach, big deck structure, and guided hold exploration when conditions and certification line up. The dive is less about cruising a reef and more about reading an intact wreck, managing current and depth, and keeping your team together through a busy, high-traffic site. Expect a two-dive day or liveaboard stop, with early departures and a guide-led plan doing most of the work.
