Sea Mates

Istria Peninsula, Croatia

Istria, with its rugged coastline, often gets overlooked for diving in Croatia, but Sea Mates offers a good reason to explore it. They’ve really leaned into the technical diving scene, with their Diamond courses being a standout. If you’re looking to push beyond recreational limits, or simply want to learn from instructors who eat, sleep, and breathe advanced diving, Sea Mates is a solid choice. We’d suggest checking their site for the full course breakdown, but expect serious training in a beautiful, if sometimes challenging, dive environment.
