Difficult one to rate, as the tour company were great, although Halong Bay itself did not live up to expectations - The rating here is for the tour company, rather than Halong Bay. Out of all the trips we did in Vietnam, this was the one I was looking forward to most, I'd always wanted to go to Halong Bay. (If you're looking for other tours, Ninh Binh is AMAZING, and also half day Hanoi sightseeing tour is really good). Anyway, can't fault the tour company. We were originally booked to go on the 2 day/1 night cruise on 9/10 Sept but due to the typhoon it was cancelled, we got a refund via TripAdvisor no problems at all. I rebooked direct with the tour company for the day cruise, originally on the Tues (where we got picked up and after about 30 mins were told that they'd just been notified that the authorities weren't allowing boats out so we got dropped back to hotel), and then Weds got cancelled, so we rearranged to Sat 15 Sept as we were doing other tours on the other days. On the Sat we were picked up from hotel and hour late, BUT traffic was horrendous, and we went to Halong Bay. The guide was great. Really informative. The driver used his phone a couple of times whilst driving which was a bit sketchy, but apart from that there were no issues. The tour/ship itself was well organised and food was good. The issue about Halong Bay is the sheer amount of people on all the tours, and the pollution in the water at the key sites. As a world heritage site I was expecting it to be beautiful and protected, but there was crap everywhere in the sea at the core tourist points. The highlight of the day no doubt was the boat ride under the cave into the bay, and we paid a surplus to go on the speed boat (250,000 dong per person, about £7.50) which was amazing value, we all loved it. The lowlight was the "swim", when I heard we'd be swimming in Halong Bay I was really excited, but it's in a little cordoned off area on the beach bit, and the water was filthy. Small chunks of what looked like polystyrene floating all over the water, and tiny bit of - what looked like - oil floating on the surface. Maybe from all the boats parked a few meters away and constantly coming in and out with passengers. I felt very dirty getting out the water but luckily there was a shower on the boat which I used. The boat was very cool inside which was lovely as very hot and humid outside. The food provided on the tour was really good too. Overall, can't fault the tour operator (well apart from the driver using his phone whilst driving passengers) but the cruise was great and very well set up, guide and staff were amazing people, but Halong Bay itself, whilst stunning, was very dirty at points which was sad to see, and way too many tourists (I get the irony of writing that as one of the tourists...) Overall, tour operator great, but Halong Bay needs some TLC to make it clean again at key points. The cave walk on one of the islands BTW was amazing, SO much bigger than we expected, and the caves were just beautiful. The final sunset party on top of the boat was actually really fun, I don't generally like things like this with people I don't know, but it was fun, and Halong Bay at night was stunning.

Haling day - All in all, it was the best experience. The location is breathtaking and amazing. Had a great time, and I hope to see you again soon. Love from India

Good tour booking service by Tuan - Good tour, specially arranged a driver to pick and drop us at our airbnb as we live outside of old quarter. Good service, will recommend to look for Tuan for your tour bookings. Tuan has many different tour packages.

Amazing experience - We had a wonderful day in Halong Bay. Clean, beautiful, and luxurious ship. The price is reasonable for a day cruise. The food is delicious, diverse, and flavorful. We have fun with the kayaking activities. The cruise also has a slide to swim into the sea, which is very amusing.

A wonderful trip - We have a wonderful trip with this company. The lunch was delicious with fresh seafood. Our tour guide was very knowledgeable and shared many interesting stories about Vietnamese culture and the history of Ha Long Bay. Would recommend fitting in this day trip from Hanoi!

Great Halong bay day tour - We very happy with the company & this day tour! Special thanks to our tour guide (Ms Hang) for this beautiful trip. Highly recommend this tour !

Average - 5/10, the ship was dirty and the captain of the boat crashed into other boats multiple times. The tour guide didn't care much for his passengers, all that stood in his mind was hurry hurry. Too many activities with to short time.

If you arrive at the meeting point on time, the bus Guide will not come. - I was in the hotel lobby at the pick-up point at 8:00. But after an hour, no one came. In the end, he is unable to join a day tour and is in a hotel. He's asking for compensation, but there's no indication he'll comply. It's OK to be late, but I wonder if you won't come. Also, the tour Guide was not contacted. It has a Rating of 1 or 0. Because I couldn't go. It may seem like a lie, but this is what happened today in reality.
