We took the signature cruise on the Bai Tu Long Bay course. Due to an unexpected incident, it was almost changed to the Halong Bay course, but Alice from Klook worked hard, and as a result, it turned out to be a wonderful trip that exceeded our expectations. The Bai Tu Long Bay route was very quiet and calm, and although the boat was not new, it was lovely and well-maintained, and everywhere felt clean. We were the only Japanese guests, and although we are not good at English, the ship's manager was very kind and attentive, so we never felt anxious. My elderly mother also enjoyed canoeing, swimming, and exploring caves. Many thanks to Alice and the wonderful crew 💖 Highly recommended!
