The best tour I had in my stay in Hanoi. It was worth every penny and I have learned the most in this night tour. A bonus really is going around with a nice weather since it’s not hot/in the middle of the day. Pls pls pls do not hesitate to book this tour. You will even have a lot of hands on experience and the guides are very knowledgeable, patient and approachable.
A must-do activity when visiting Halong Bay. The boat is large and new, with excellent facilities. The food is delicious, and the drinks (at your own expense) are reasonably priced. Highly recommended.
