I have been in Croatia a bunch of times and I think that Rovinj is the
best location for diving (if you like wrecks that is). The viz is
great but not the best around Rovinj but the wrecks are. I did about
ten dives on the Baron gautsch (viz around 30 meters) and have not
seen all of it yet (you can go way down into the wreck with an
excellent engine room). The Istra (Hans Schmitt) is also a big wreck
and fun to dive on (also good viz). In the Rovinj region there is also
the Guiseppe Dezza and some other wrecks but they are on a muddy
bottom. Bad viz on those wrecks...around 5 meters.

If you are not interested in wrecks but just great viz and fish then
you have to go to the island of Cres and Mali Losinj. Rule of thumb:
more south = more viz.

I did the diving with these guys: http://www.diver.hr/.

This is the "diving in foreign countries" section of our archive and
you will find a few croatian photo albums here. No hot-stuff...just
some amateur underwater pictures.

Rovinj is 'by the way' also a nice city just to hang out, walk around,
have a beer and a bite to eat.

Next summer I'm going to the Zadar region to check out the diving.

Have fun,
