Sinai Liveaboard Diving

The Sinai coast around Sharm el-Sheikh is the classic Red Sea combination trip — sheer coral walls at Ras Mohammed National Park, the legendary SS Thistlegorm wreck, and the drift-diving reefs of the Straits of Tiran, all within a few hours' cruising of one another. It's often considered the birthplace of Red Sea liveaboard diving and remains the benchmark against which other Red Sea itineraries are measured.

A standard route strings together Ras Mohammed's Shark and Yolanda Reefs, the Thistlegorm wreck in the Straits of Gubal, and the four reefs of the Straits of Tiran (Gordon, Thomas, Woodhouse, and Jackson). Longer trips sometimes extend south toward the Brothers Islands or Daedalus Reef, but the Sharm-Ras Mohammed-Tiran-Thistlegorm loop is the core of any Sinai itinerary.

Most recreational dives stay in the 33-98 ft (10-30 m) range, with the walls and drop-offs at Ras Mohammed and Tiran often planned as multi-level dives that start deep along the wall and finish shallow on the reef top. The Thistlegorm sits on a sandy bottom at 98-108 ft (30-33 m), with its main deck around 49 ft (15 m) — within recreational limits, but demanding for buoyancy control inside the cargo holds.

Water temperature ranges from roughly 68°F (20°C) in winter to 82°F (28°C) in peak summer, with the most comfortable conditions — about 73-82°F (23-28°C) — found in the spring and autumn shoulder seasons. A thermocline can knock several degrees off at depth even in summer, so a 5mm wetsuit (or thicker in winter) is worth packing.

Open Water divers can comfortably handle Ras Mohammed's shallower reefs and the Thistlegorm's exterior and open deck, but Advanced Open Water (or equivalent logged experience) is strongly recommended for the region as a whole. Wreck penetration inside the Thistlegorm's holds and drift diving in the Straits of Tiran are best attempted with wreck or drift specialty training, or a solid dive count and a good guide.

Expect grey reef and whitetip reef sharks, occasional hammerheads, Napoleon wrasse, large groupers, batfish, and dense schools of barracuda and jackfish along the walls. Turtles and eagle rays are regular sightings, and whale sharks pass through seasonally, though they're never guaranteed.

March through May and September through November offer the best balance of warm water, strong visibility, and calmer surface conditions. Summer (July-August) brings the warmest water and often excellent visibility but also stronger winds and heavier boat traffic; winter is quieter but cooler and occasionally choppy.

Ras Mohammed is reachable on a day boat from Sharm el-Sheikh, only about 30 minutes away, so it isn't liveaboard-exclusive. Most liveaboard itineraries still include it as a stop, since it lets guests dive it early or late in the day and avoid the day-boat crowds.

The Thistlegorm is a remarkably intact WWII cargo wreck stacked with motorbikes, trucks, rifles, and munitions, dived both for exterior swim-around and for penetration dives through the cargo holds. Penetrating the holds involves silt-outs and confined spaces, so it's best done with a guide experienced on the wreck and, ideally, some wreck-diving training; the exterior and open holds are manageable for less experienced divers on a calm day.

A Sinai-focused itinerary typically runs 3-4 nights, often combined with a run south to the Brothers Islands or Daedalus Reef to build a full 7-night trip. Shorter 2-night mini-cruises covering just Ras Mohammed, the Straits of Tiran, and the Thistlegorm are also common out of Sharm el-Sheikh.

Currents can run strong and unpredictably around Ras Mohammed's headland and through the Straits of Tiran, and boat traffic is heavy near popular sites like the Thistlegorm and Shark Reef, so surface marker buoys and tight group discipline matter. Ras Mohammed National Park also enforces marine-park regulations and an entry fee (as of 2026), and touching or collecting coral is prohibited throughout the protected areas.

There's genuinely something for every level — sheltered bays and shallow reef tops work well for newer divers, while the walls, wrecks, and drift sites reward more experience. That said, the sites the region is famous for are largely deeper and current-swept, so divers get the most out of a Sinai trip with at least Advanced Open Water certification and some logged dives under their belt.
