This reef lies 48km from Port Sudan and surrounds a gorgeous lagoon which can be accessed through a narrow strait having been blasted by Cousteau himself. Outside of the lagoon, just 100m from its entrance is where in 1963, Cousteau built Precontinent II – his futuristic world. Here he conducted his underwater experiments and today the Precontinent provides an insight into the lives of those who had lived under the water in futuristic looking buildings and conducted research on marine life. The cages used for shark feedings still lie where they used to in Cousteau’s time. Sharks still come here as they did decades ago.
