I remember diving the Canyon in Dahab. It is a 30m dive. We went into the cave at a hole about 18m down and you end up in a cave. This was the most spectacular dive I have done. We lay on our backs at 30 m looking up and you could see the light penetrating the cavern.
We exited the cave through a hole big enough for us to go out one at a time.
We then sat in an area called the fish bowl, where you are in the bowl and the fish are on the outside.
