In Halong, traditional bus tours are not the norm. The primary attraction here is the bay's picturesque islands, which draw millions of tourists annually. Halong sightseeing tours are typically conducted on special boats, and the duration can vary from a few hours to several days, depending on your preferences.
The cost of a one-day Halong Bay tour, including stops at the main caves, usually doesn't exceed 80,000 VND. If you opt for a three-day cruise, the price may go up to 630,000 VND. However, keep in mind that the cost of a Halong excursion depends not only on the duration or class of the vessel but also on the pricing policies of the tour operators.
