Why dive here
Blue Hole is a cenote dive where divers can encounter dolphins, spinner dolphins and whale sharks. Water ranges 21-28°C, warmest July, August, September.
The Blue Hole, just north of Dahab, is more than a big sinkhole, it's a rite of passage for many Red Sea divers. You start with an easy entry from the shore, finning over a shallow reef teeming with fusiliers before descending into the deep blue abyss. The dramatic vertical walls drop to 100 meters, creating an almost cathedral-like feel, and you’ll often spot Indian Ocean bottlenose dolphins cruising the edges. We like to cross the saddle, a shallow coral garden that connects the hole to the open sea, before re-entering the main cavern. Keep an eye out for the African eel blennies darting into crevices and the occasional Crown of Thorns starfish clinging to the coral. It’s a site that suits those comfortable with depth and a bit of open water exposure.
