Thomas Reef Liveaboard Dive Site

Thomas Reef is a reef dive in Straits of Tiran, Egypt, within an area known for current-swept reefs and deep channels. The precise entry point and route depend on current, weather and the cruise director’s assessment, so an itinerary reference should not be treated as a guarantee that every departure will dive the site.

The most productive side of the reef changes with the water movement. Divers should remain close to the guide, control their depth and be prepared for a negative entry or blue-water pickup where the briefing requires it.

A liveaboard is the practical way to combine this site with several dives across Straits of Tiran. Carry a surface marker buoy, follow the boat’s current and pickup procedures and use nitrox only when qualified and after analysing the cylinder. Wildlife encounters and visibility vary naturally and cannot be guaranteed.

Other sites in this part of the itinerary include Jackson Reef and Woodhouse Reef. Compare Egypt liveaboards and review the Egypt liveaboard destination guide before choosing an itinerary.

The Thomas Reef dive site in Egypt is visited by 20 dive liveaboards. The highest customer-rated liveaboard scores 10.0 out of 10. Prices across these liveaboards start from £66.00.

If you want a more intimate experience, the smallest liveaboard in this selection of the Thomas Reef dive liveaboards is Red Sea Blue Force 2, which has 9 cabins, accommodates up to 18 guests, and is 28 m in length. If you prefer a larger boat, Ocean Lovers Liveaboard, which is 45 m in length, has 16 cabins, and accommodates up to 32 guests.

To dive the Thomas Reef dive site, the minimum diver certification ranges from Open Water Diver to Advanced Open Water Diver, and logged dive requirements range from no minimum number of logged dives to minimum 50 logged dives. So be careful when you choose a liveaboard that has the Thomas Reef dive site on its itinerary, to make sure both your dive certification and level of experience match its minimum levels.
