Photo Gallery Diving the Blue Hole

It doesn't have the nicest coral or the most fish, but the Blue Hole in the Gulf of Aqaba on the Sinai Peninsula is a magnet for divers. One reason is the deep tunnel that many want to traverse. Some don't come back. Here, two divers just outside the Blue Hole in 2005.

Many of the problems in the Blue Hole are a result of depth. Compressed air can only be used to a depth of 56 meters. The tunnel's exit is one meter lower than that. Here, a team returning from a deep dive just outside the Blue Hole.

The Red Sea is considered the Holy Grail of diving due to the variety of coral and fish to be seen at relatively shallow depths. Here, a porcupine fish swimming near Sharm el-Sheikh.

Divers come from all around the world to enjoy the sights in the Red Sea waters.
