Hi Paddy,
Greetings from another fisherman! As Alan says, shore fishing in Sharm is not really the done thing and not allowed in the majority of places where you can access the sea. I would imagine the scenario of you or I sitting peacefully waiting for a bite and then hauling in a 3or4 pound parrot fish, only to find our self surrounded by a lynch mob of angry snorkellers/divers! Believe me, once you have snorkelled in the Red Sea and seen the wonders that it holds within its coral reefs, you will not want to be fishing over them!
Having said that, it is possible in Sharm, to be taken out "deep water" fishing by some of the local fishing boats, quite often on a night trip. These trips can only be arranged when you are in Sharm by approaching somebody whom you identify as possibly being able to help you.
In closing, I would say that I have fished in a lot of countries around this world we live on, but after my first visit to the Red Sea, I was a far happier watcher rather than catcher, whilst in Egypt!
Regards,
Roger.
