The Halon Bay tour was okay. The drive to and from the Bay was very long, mainly due to the heavy traffic and sometimes poor roads. It would probably be better to do an overnight tour but I'm not sure how much more there would be to see. Personally, I found the scenery in Guilin China and the coast of Thailand to be more scenic and more enjoyable trips.
The trip was amazing. visited the nice scenery of Halong Bay. lunch wasn't fantastic but still not too bad. we had a slight hiccup along the way back but all was settled. the tour guide English was muxh better than the previous one. he was also very friendly and engaging. the tour bus isn't the most comfortable ride for the 3.5 hours trip back and fro.
This was a fantastic trip, when in Vietnam definitely try Holong bay, its stunning. From views, to comport to fun to yummy food, each side is splendid. Klook partnered with Holong Bay Phoenix cruiser for the trip & boat, guide, activities, food all were good. The only reason for not giving 5 star review is the pricing. If you book with local agencies you might get a cheaper deal, but Klook for sure is reliable.
Scenery is beautiful. Kayaking was fun despite it was only 30 min. The cave is interesting. However, journey from Hanoi to Halong Bay was not comfortable
