The Blue Hole announces itself from the road: a break in the reef shelf where the turquoise shallows suddenly darken to cobalt. You'll climb down over rocks worn smooth by a decade of divers' booties, entering water that's deceptively calm at the surface. The hole itself is roughly 200 feet across, its walls descending vertically into a void that has claimed over 130 divers. Memorial plaques dot the entry rocks, testaments to the seductive pull of the deep.
“The hole's vertical architecture creates a natural laboratory for observing deep-water species in relatively accessible depths, though its deadliness demands respect and proper training.”

Stay shallow and the Blue Hole is simply spectacular snorkeling. You'll float above gardens of soft coral, watching schooling fusiliers form silver clouds that shift and reform in response to unseen cues. The wall is a vertical aquarium: lionfish perch on ledges, their venomous spines fanned like Victorian collars; cleaner wrasse operate their stations, servicing groupers twice their size. At 90 feet, an archway called The Arch tunnels through the reef wall to the open ocean—a passage that looks deceptively simple but requires technical skill and nerve to navigate safely.
The beach community here is small and specific: freedivers pushing their breath-hold limits, technical divers planning decompression profiles on slates, instructors leading nervous students through their first deep dives. You'll sit at beachside cafés where the talk is all nitrogen narcosis and dive computers, watching kiteboarders carve across the shallows to the north. The Sinai mountains rise behind you, barren and biblical, indifferent to the human dramas playing out in the water below.
