I have been twice diving in Red Sea.
The first was a week boat trip from one wreck to another. Quite interesting. We have seen the famous English Second World War ship wreck with tracks, tanks, motorcycles and so on. Many ship wrecks different nations from different times. The oldest was Greek wooden steam ship 130 years old. Only steam tank and a few metal constructions survived until now.
The second was a shore diving from different places 200 kilometers south from Hurgada. As usual, there was beautiful corals, a lot of small animals, some time waves and fun, fun, fun.
