For dive site description we make an exception being only of local interest. We recommend you dive also at home and not only on your holidays abroad. You say "yugh!" or "bbrrr!". Don't. With the proper thermal protection you find it's okay. And some very nice dives can be made in your own country. Sign up at a local dive club and check it out yourself. For sure you will be better prepared for your holiday dives if you dive regularly also at home.
