A blue hole is a large marine cavern or sinkhole, which is open to the surface and has developed in a bank or island composed of a carbonate bedrock (limestone or coral reef). Their existence was discovered in the late 20th century by fishermen and recreational divers. Blue holes typically contain tidally influenced water of fresh, marine, or mixed chemistry. They extend below sea level for most of their depth and may provide access to submerged cave passages. Well-known examples are the Dragon Hole (in the South China Sea) and, in the Caribbean, the Great Blue Hole and Dean's Blue Hole.

is a historic and archaeological city in southern Jordan. It is adjacent to the mountain of Jabal Al-Madbah, in a basin surrounded by mountains forming the eastern flank of the Arabah valley running from the Dead Sea to the Gulf of Aqaba.The area around Petra has been inhabited from as early as 7000 BC, and the Nabataeans might have settled in what would become the capital city of their kingdom as early as the 4th century BC. Archaeological work has only discovered evidence of Nabataean presence dating back to the second century BC, by which time Petra had become their capital. The Nabataeans were nomadic Arabs who invested in Petra's proximity to the incense trade routes by establishing it as a major regional trading hub

The three pools part of Three Pools is essentially a dead reef. There is a guy with a whistle telling snorkellers not to touch the coral. But it's too late for the pools themselves, almost all of the coral is dead. There is a small drop-off beyond with ok coral coverage, but literally all of the other dive sites in Dahab Town have way more life. I don't know what happened here. Apparently a few months ago it was not like this and I can't see how even a lot of incompetent swimmers could cause this level of die-off. There is broken dead coral, but mostly there's unbroken, unbleached, sediment covered dead coral. The only thing I can think of is suncreen. This should be investigated.

Wadi Gnai is a little oasis and one could say that it is located directly behind the Sunsplash Divers Resort’s backdoor. Hike through this calming landscape, into the palm grove and the abandoned gardens of the Bedouins. As there’s water in Wadi Gnai it is always lush and green – and in the rare event of rain you will be able to find many different types of desert flowers in full bloom.
