Red Sea Explorers' largest liveaboard: 37.5m, 28 guests across 14 cabins, running the same GUE-leaning offshore and deep-south Egypt route catalogue.
The largest reef in Egypt's St John's: a big oval coral reef with sunlit tunnels, a fishy south plateau and drift walls in the far-south Red Sea.
Last updated June 2026
A Gota Kebir dive is shaped by the current. In calm flow, you drop onto a coral wall and drift the perimeter, passing gorgonian fans and soft-coral overhangs before cutting in through the shallow tunnels. These are wide, sunlit swim-throughs in the reef plate where shafts of daylight pick out the coral roof, a gentler cousin of the light show at [st-john-caves]. They sit shallow, around 6 to 10 metres, and stay in the daylight zone, which is why they work as an approachable taste of overhead-light diving. A torch helps with the darker pockets, and good buoyancy keeps the silt down.
The set-piece is the south plateau, where jacks, snapper and schooling barracuda gather over the reef edge. It is the reliable big-fish moment of Gota Kebir, well short of a shark dive but a genuine wall of fish. When the boat positions divers at the northern tip, the dive changes character. The current splits and accelerates there, drift discipline matters, and the open blue is where the occasional manta or reef shark passes. That tip is the most demanding part of the site in flow. Most groups run the whole thing as a drift, finishing near the moored boat or to a zodiac pick-up with an SMB up.
Gota Kebir is St John's at its most expansive. Where the area's dedicated cavern site is a compact maze you can lap in one dive, this is a sprawling reef big enough that a single tank only samples it, the largest in the system. Three things set it apart. The first is scale: it is varied enough to combine a drift wall, a fishy plateau and a tunnel system in one site, the do-a-bit-of-everything St John's dive. The second is those tunnels, shallow enough to be an accessible introduction to overhead-light diving rather than a true cave. The third is the contrast between the calm reef and the working northern tip, where the current and the blue open up.
It is a scenery and structure reef, not a pelagic guarantee. As of 2025-2026 the Deep South is living through a regional bleaching event, so the living-coral cover is patchier than older accounts suggest, even where the structure stays spectacular. The honest read is a big, beautiful, varied coral reef best dived for its topography, with the plateau fish and the chance of a manta as the bonus.
Plan around the current. Most of the reef is moderate, but the northern tip splits and accelerates, so dive it as a drift, follow the guide's plan and carry an SMB for the pick-up rather than fighting the flow. The tunnels are shallow and daylit but still an overhead, so keep your trim, hold buoyancy off the coral, carry a torch and do not go beyond your certification. The walls reach the 40 metre recreational limit with technical depth below, so set a maximum and a computer alarm and watch your gas.
This is remote, expedition diving, dived only from a liveaboard on a long southern crossing to uninhabited reefs. Advanced Open Water is the sensible level for the full dive, though the shallow garden and tunnels suit less-experienced divers with a guide. Nitrox is worth taking for the shallow, repetitive days. The nearest recompression chamber is around 200 kilometres away at Marsa Alam, so dive conservative profiles and carry DAN-style insurance.
What makes this dive site stand out.
A big oval reef combining a drift wall, a fishy plateau and a tunnel system in one site.
Shallow daylight tunnels at 6-10 m pierce the reef plate with shafts of light.
Jacks, snapper and schooling barracuda gather on the southern reef edge.
The current accelerates at the north tip, the demanding part and the pelagic chance.
The gentle tunnels are an accessible taste of overhead-light diving.

The shallow tunnels and inner reef are accessible, but the depth on the walls, the drift profile and the strong split current at the northern tip push it beyond beginner territory.
