4.1 Day 1: Exploring Ha Long Bay
In the morning, you should depart early to arrive in Ha Long before 10 AM, avoiding peak hours. After leaving your luggage at the hotel or checking in early (if possible), head to the port to begin your bay tour – the most important part of the trip, and the first answer to the question Where to go in Ha Long in summer .
