The canyon is one of the most popular dive sites in Dahab and an essential dive for all fanatics of caves and cavern diving. The Canyon is, itself quite a phenomenon. Up to 10 m deep and virtually closed over at the top, it snakes its way up from the depths, to emerge in a large glass fish filled coral dome, the fishbowl. After an easy shore entry, you cross a sandy lagoon that opens onto a gently sloping reef marked with coral heads. The amazing and eerie canyon soon comes into view. It has three main openings. At about 12 m is the fishbowl. Below that is another large bowl, opening at about 20 m. Deepest of all is a narrow exit at 52 m. In between these openings the walls have grown together to virtually close over the top of the canyon, forming a tunnel. From the top it has the appearance of the fluted mouth of a clam shell. Descend into the Canyon at 20 m and drop to the bottom which sits at around 30 m. Make sure you stick to a depth well within your ability. Take a minute at bottom and enjoy the magnificent view, the light coming through the crack that forms the entry of the canyon while you sit in semi-darkness, it is an amazing sight. From here you exit through the fish bowl. Finish the dive by swimming through a sensational coral garden at about 8 m. Very good chances to find the resident octopus.
