A long oval reef breaking the surface in Egypt's far-south St John's: drift walls, a south plateau of jacks and barracuda, and tunnels in the southeast wall.
Last updated October 2026
The reef is a long oval, more than 800 metres from end to end and breaking the surface, so the dive is decided by the flank you are put onto. The east side is normally dived in the morning light and the west in the afternoon, both as deep sloping reef of brown soft corals. The northern end holds two plateaus and the place where the current often splits; whitetip reef sharks and bluespotted rays are named for those plateaus, and the splitting flow sets the pace at this end.
In the southeast corner the wall breaks into deep fissures and tunnels that can be entered. A dive light earns its place here for the darker swim-throughs. The south slopes away as a plateau with unicornfish, rabbitfish, anemones in the shallows and green turtles grazing there, and jacks and schooling barracuda over the plateau and the occasional manta passing.
Gota Kebir packs several different dives into one reef. One operator on the route singles out the tunnels and the south plateau, and the reef is large enough that one tank only ever samples a single flank. A day can run east wall, west wall, tunnels and plateau, each with its own character.
Gota Soghayr, the smaller sister reef covered on [small-st-john], lies 3.4 km to the west.
The current is the variable that matters. At the northern end it can strengthen and turn quickly, so dive it as a drift on the guide's plan and have a surface marker buoy ready before you ascend.
The tunnels in the southeast wall are an overhead: keep your trim, hold buoyancy off the coral and turn back at the edge of natural light.
What makes this dive site stand out.
Over 800 m from end to end, with walls, plateaus and tunnels in one structure.
Fissures and tunnels in the southeast wall can be entered.
A sloping plateau where unicornfish and rabbitfish live and green turtles feed.
The current often splits over the two northern plateaus.
Peak pelagic activity falls in May-June and October-November.
Operators on the route set Advanced Open Water as their requirement, and one notes that many dives go below 18 m. The shallow reef top and the plateau near 15 m sit above that line.
Summary
Moderate to advanced: depth on the flanks and a current that can be strong and change direction quickly.

No. Accounts disagree. A diver recalling the route up to 2010 saw shark activity across several St John's reefs including this one, and a diver in 2025 reports that St John's has no sharks at all. Whitetip reef sharks are named for the northern plateaus, so a sighting is possible, but treat it as a chance, not the reason to dive here.
One operator on the route describes the tunnels as suited to novices. They are still an overhead environment: fissures and tunnels that can be entered, in the southeast wall. Stay within natural light, within your own training, and let the guide set the limit, because the current that shapes the rest of the reef does not switch off at the tunnel mouth.
