I'm looking for some places that have good wreck and cave diving in Europe. I figure the Channel, the N Sea near the Channel, the Baltic, etc. are probably good areas for wrecks but what about other areas? Are there any lakes that offer good wreck diving? Are there any areas that offer good cave (not cavern) diving? By good I mean multiple locations sort of near each other so that over the course of a few days you can do multiple sites.
