Top things to do in Halong Bay

Halong Bay is vast and picturesque. The highlight was Dong Thien Cung. The size and formations within the cave were dramatic. Luckily most ot the bus ride from Hanoi is on a freeway, but even with that the bus ride took 2.5 - 3.0 hours one way

Awesome Service. They are fast in responding with enquiries/updates via Whatsapp. Mike from A21 Tours make sure everything goes smoothly by updating me on the status of the arrangements. We took a Wonderbay Day cruise in Halong Bay via A21 Tours. We stayed a night in Halong bay thus did not take the transport back to Hanoi provided by Wonderbay. A21 Tours provided the return trip to Hanoi using Luxury bus with NO additional charges. We also took their airport transfer to/from Hanoi by A21 Tours. Everything went as beautifully planned and scheduled. This is our first trip to Hanoi/ Halong Bay, A21 Tours makes our trip a breeze. Effortless and enjoyable. Totally satisfying and contented. Will strongly recommend A21 Tours.
