About

The northernmost marina in Croatia and the largest in the ACI group with 475 berths in the water, a few hundred metres from Umag's old town. It is a port of entry from April to the end of September, which for many boats coming down from Italy or Slovenia makes it the first Croatian stop. It carried a Blue Flag in 2026.
