"UNESCO bay, Mediterranean breeze"
World Famous
Ha Long Bay
Vietnam
Thousands of limestone karsts and islands rising from emerald waters. UNESCO World Heritage and one of the world's most recognizable seascapes.
European Alternative
Bay of Kotor
Montenegro
A dramatic fjord-like bay surrounded by towering mountains and medieval walled towns. Cruise between ancient villages, hike fortress walls, and swim in crystal waters.
Why These Two?
Both are UNESCO-listed bays with dramatic karst/mountain formations rising from calm waters, best explored by boat.
