What to wear
Wear warm clothes like a thick jacket, sweaters, and long pants. A scarf and hat are helpful if it’s windy.
Since there aren’t many chances for swimming, you don’t need to pack lots of swimsuits. However, bring at least 1 or 2 pairs of waterproof clothes, since kayaking is still available and you might want to avoid getting wet during that time.
Event
January 1st marks the beginning of the new year. While the main countdown and parties happen on December 31st, some cruises still host small celebrations on New Year’s Day. If you’re on a Halong Bay cruise, don’t miss the chance to enjoy a festive Gala dinner.
