Maybe not all of this belongs to europe but might give you some ideas for your next trip outside europe.
The past
Diving since 1992 I have been to some very nice places with really nice dive sites
After my OWD at the end of 1991 I started with a 2 week trip to Kuredu Island (Pro Divers), Maldives
The next trip took me to for one week on a wreck dive specialty to France. I dove at the Donator, Le Greg and some other WW-vessels and civil freighters. But no penetration.
After this first contact with wreck diving it was time again for fish. So I spent a week shore diving in Safaga, Egypt plus a week live aboard with Sinai Divers to the south aboard the Ghazala Voyager.
Due to business reasons I had a little break before the next trip. In 1996 I went to Egypt again. Friends seduced me to do a live aboard safari to the south again. This time aboard the Ghazala Explorer.
After two times Red Sea I thought it is time for a different location. Someone in our group said Philippines. The sound of this word made us dream of white beaches, romantic bays, ie. To come to the end - 1998 we spent three weeks at the Coco Beach resort at Mindoro island, Philippines. Very nice relaxed diving. You might think boring - Not one day, some days current but not too much. Just enough ti drive you along the coral walls.
Between 1998 and 2002 I did a lot of diving in Germany and Austria. Especially in Austria diving in most of the lakes offers you a viz up to 50m, 100m and more. Attersee, Fernsteinsee, Samaranger See and Blindsee are here the top spots.
2002 I came back to the Philippines and back to Mindoro island. But this time - due to a special offer during the BOOT 2002 exhibition - we stayed with
Cocktail Divers at the Garden of Eden Resort. Three top class wrecks just in front of the beach (500m to snorkel). Top class not because of their size but the native animals. Pipefish, frogfish, moray eels, stonefish, dragonfish all at a place of less than 5000 square metres.
And finally in 2003 it had to be Egypt again. This time we made our decision on a one week trip aboard the safari boat Ghazala Voyager to the north (Sinai peninsula) where all the big wrecks are. Ghiannis D, Carnatic, Thistlegorm, ie. On an early morning dive friends of mine spotted a tiger shark. Stuff for hours of chatting. Unfortunately on the fourth day on board I had my little toes broken and was unable to wear boots or fins without boots.
The future
And now ??? Only 2 days and a few hours left over to our departure to Hongkong, transfer via Cebu to Bohol.
