There were about 25 people in our tour. They did a quick job of picking everyone up but with so many pick ups it took quite a while to get going. Our tour guide was really great and funny. The bus was a little cramped and there was no wifi even though it said there was on the bus itself. It was okay for me but maybe not for others. The ride was really fascinating to see the northern coastal countryside. I wish we could have stopped at a local coffeee shop or lunch spot instead of a strange factory place they brought us to. The prices here were incredibly high and the exchange rate was criminal. Bring your own food and drink and you'll be fine. Bathrooms here are very clean and there is tp. The lunch on the boat was fine but not outstanding. The views of the bay were really beautiful though. We chose to kayak as our activity and that was the highlight of this tour. We also saw a cave but that activity was very rushed. It was a busy tour but if you only have one day, it's a good option. If you can afford a more expensive tour, I would recommend doing something as a smaller tour group. This tour was a good value for the price though.
Eigentlich sind diese Trips inzwischen der reinste Massentourismus - was nicht jeder mag. Allerdings hat nicht jeder Interessierte ein eigenes Boot...Unsere Tour war perfekt organisiert, sehr gute Reiseleitung, die auch in der Tropfsteinhöhle sehr gute und ausführliche Infos gab. Wir haben trotz Vorheriger Bedenken diesen Trip für einen einzigen Tag von Hanoi aus gebucht. Also ohne Übernachtung auf einem Kahn. Das war eine gute Entscheidung.
