    Brennsee in Istria offers a different kind of dive. This isn't a coral reef; instead, you'll explore a freshwater lake environment. Expect to see freshwater fish, perhaps some submerged logs, and interesting bottom topography. It’s a good option for divers looking for something a bit unusual, or for those wanting a freshwater dive experience away from the coast.
