Murter, ACI Marina Jezera

ACI Marina Jezera sits tucked into the southern end of Jezera Bay on the southeastern coast of Murter Island, and it's one of the cleaner, better-run marinas you'll find in the region — it holds a Blue Flag eco certification and has a reputation for friendly, on-the-ball staff. Rates are pretty standard for ACI (think around 80€ for a ~10m boat), and you're well-placed to explore the Kornati archipelago or nip over to the nearby town of Tisno. It's the kind of spot where the organization actually matches the setting, which isn't always a given in this part of the Adriatic.
