Snorkeling in Croatia
Including Brijuni National Park, Cape Kamenjak, and Dubovica Bay. On the map.
The vibe
Floating in these waters feels like peering into a giant, sun-drenched aquarium where the visibility often stretches for dozens of meters. Late spring through early autumn is the ideal window, as the water warms up enough for long, lazy sessions drifting over rocky drop-offs. It is a very accessible, DIY activity that feels perfectly natural to pick up while island hopping, requiring nothing more than your own mask and fins.
