The Blue Hole is 200m in diameter and plunges deep. It is a dive that needs to be treated seriously many have lost their lives here, disoriented by narcosis. It has been explored to a depth of 195m but is believed to be deeper than 300m in parts. Quite apart from the abyss itself there is a tunnel leading from the Blue Hole out to the sea at around 56m which has the appearance of a brilliant blue window. Located about thirty minutes jeep ride from Dahab, it is accessible from shore with entry into the blue water just a few metres from the rocky shoreline. Divers can then drop down an enclosed chimney in the reef exiting at 30 metres or so onto the sheer wall. Images
