Ha Long Bay is one of the most visually extraordinary environments in the world, with 1,969 limestone karst islands and islets rising abruptly from the emerald waters of the Gulf of Tonkin in northern Vietnam. The bay, a UNESCO World Heritage Site since 1994, covers an area of over 1,500 square kilometres and forms a natural labyrinth of channels, lagoons, sea caves and floating villages that is navigable only by sea. Yachts available from 125,000 euros per week in this setting are typically 40 to 60 metres, with crews of eight or more experienced in the local navigation.
The geology of Ha Long Bay is the result of 500 million years of karst formation and sea level change, producing islands with vertical cliff faces, hollow cave systems and hidden lagoons entered through narrow sea arches. Hang Sung Sot, one of the largest cave systems in Vietnam, contains chambers the size of cathedrals. The floating fishing village of Cua Van provides a living example of the maritime culture that has existed within the bay for generations.
At 125,000 euros per week, the charter fee covers the yacht and crew. The Advance Provisioning Allowance of 25 to 30 percent covers fuel, provisioning and port dues. The nearest embarkation point is Ha Long City, accessible by road from Hanoi in approximately two hours. All-in weekly budgets typically run to 155,000 to 165,000 euros.
The best charter season in Ha Long Bay runs from March through May and September through November, avoiding both the summer heat and humidity and the winter mist that can reduce visibility significantly in January and February.
