3 day Liveaboard to thistlegorm wreck was my last great diving trip.... if wreck diving is the ultimatum of diving, then Thistlegorm is the ultimatum of wreck. 140m long, 3 stories, lots and lots of well preserved weaponry of WWII.

also went to Ras Mohamed and did 2 great drift dives there, amazing bottom and lots of marine life.
Careless reef in Hurghada is also one of the best dives in that trip. Lots of gaint morays' turtles and baracudas

Water is crystal clear with 30+ meters visibility, water temp around 24 degree celsius and calm surface except for thistlegorm which was pretty rough surface as it was bombed by a german plane in ww2 (didn't hit the reef as most of redsea wrecks, nearby reefs causes calm surface)

As for topside, the weather is really good, I slept all nights on the sun deck of the boat. Only used the room for bathroom and storage. Before starting the livaboard I arrived at hurghada two nights earlier, learned water skiing and enjoying the nights in local pubs, really fun.

As for prices, Egypt is the place you go if you want to plan a low budget vacation yet as exciting as anywhere else in the world, topside or underwater.. trust me you'll enjoy it. You could get the 3 days livaboard as low as 200 euros
