    Mixed reviews - Ups and downs

    This trip had ups and downs. My main concern is it has a target demographic of probably 17-28 years old, not suitable for young kids unless they are super athletic as the kayaking can be quite strenuous and the dark cave can really scare the kids. Our family is use to kayaking and out doors activities so this wasn’t the first time doing this sort of activity. We were travelling with our nieces and nephews which an age group of 36,32,31,14,12,10 years old and we really found that this was not at all kid friendly. The kayaking starts off fine, you get off the boat start paddling but as soon as you get to the cave area there is a strong current which makes it quite difficult for the kids to paddle. There is only one guide, so if you fall behind, you get left behind… no turning around and checking if everyone’s ok. We got to the cave and the tide was very high - the guide attempted to take people through and it was quite dangerous, no light except for one torch at the front of the line for the guide etc. All the kids we were with didn’t like it and were quite scared. After the turning back from the cave the guide headed off again - we were stuck in a strong current and couldn’t get out of it but then were later told you needed to stick by the rocks to skip the current this wasn’t explained as the guide just goes on with no really explanation and at the point it was too late, we were stuck and got very tired trying to fight our way out of it. There was another family of 4 there in exactly the same situation as us who also said they felt like it was not kid friendly, which is fine that’s it not but I think it would be good to explain this to families before they book it. The guide didn’t come back at all to check (it had been 10 minutes or more we had been left for), just carried on with the tour so we decided to make our way back to the boat. We would have liked some warning that it was going to be like that as we would have happily just kayak ‘d around the lovely rocks near the boat and completely avoided the current. I think two guides would be helpful to improve the safety of this tour. The boat was really nice, the food for lunch was so delicious and plenty of it. It catered to differently dietary needs as well. The water around Halong bay had quite a lot of rubbish in it and was fairly sad to see. Lan Ha Bay seemed to have less rubbish and seemed cleaner. On the way back we stopped off monkey island (this wasn’t written on the itinerary). We found this to be very unethical - The macaques on this island were not native to monkey island - they were moved from Thailand to Vietnam (Cat ba) for tourism purposes which ethically is quite questionable. The island itself does not have the resources to sustain the number of macaques on the island and they rely heavily on the tourism to maintain numbers of 60+ (the tour guides and tourist feeding them) and without tourism the numbers drop to 20-30 (we were told this by the guides as well, I don’t think he realised the impact of this). The tour guides take cookies and things to feed the macaques which is a horrific diet for them and there was a lot of teasing, chasing, splashing the macaques which again really isn’t ethical. It causes the animals to get very frustrated and show a lot of aggression towards the guides and visitors once the food is no longer available. We were really disappointed to see this happening and we refused to go onto the island. Reading reviews there have been quite a few injuries caused by the macaques to people - needing hospital visits and rabies treatment. We were just hoping that this review discourages anyone from taking the risk of going onto the island and also helps hopefully prevent the ongoing unethical treatment of the macaques on this island. The guides hopefully will learn that this is not an ethical way of interacting with wildlife and this is unsafe for visitors. Mixed review really but hope this helps.

    Cat Ba Island,Lan Ha Bay on Serenity Grandeur 1 Day Cruise: questions travelers ask

    Practical detail on this experience, plus the wider planning questions for Hanoi.

    How much does Cat Ba Island,Lan Ha Bay on Serenity Grandeur 1 Day Cruise cost?

    +

    Prices start at $70 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Hanoi usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.

    How long does Cat Ba Island,Lan Ha Bay on Serenity Grandeur 1 Day Cruise take?

    +

    Plan for about 12 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Hanoi is not rushed.

    Is Cat Ba Island,Lan Ha Bay on Serenity Grandeur 1 Day Cruise worth it?

    +

    It holds an Outty Ranking of 48 out of 100, which we label "Worth a Look". That score blends traveler sentiment (4/5 across 2 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable outdoors in Hanoi, and how flexible the cancellation terms are.

    Can I cancel or reschedule Cat Ba Island,Lan Ha Bay on Serenity Grandeur 1 Day Cruise?

    +

    No. This experience is sold on a non-refundable basis, so only book a date you are confident about. Similar experiences in the city do offer free cancellation if flexibility matters more than price.

    Is Cat Ba Island,Lan Ha Bay on Serenity Grandeur 1 Day Cruise suitable for kids and families?

    +

    Yes, all ages are welcome. Families should still weigh the 12-hour running time, and strollers are easier on the earlier, quieter departures.

    How far in advance should I book Cat Ba Island,Lan Ha Bay on Serenity Grandeur 1 Day Cruise?

    +

    Around 1 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Hanoi can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.

    What should I bring or wear?

    +

    Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Hanoi and add a light layer if any part of the 12-hour experience runs outdoors or after sunset.

    Where does Cat Ba Island,Lan Ha Bay on Serenity Grandeur 1 Day Cruise start and how do I get there?

    +

    The exact meeting point and directions are on your voucher once you book, and they sit in central Hanoi within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.

    What are the best things to do in Hanoi?

    +

    On Outty we rank every Hanoi experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Ninh Binh Day Trip from Hanoi with Tam Coc or Trang An & Mua Cave, Ha Giang Loop Tour 4 Days 3 Nights with Ha Giang Vision Tour, Halong Bay Day Tour With Titop Island, Cave, Kayak & Lunch. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.

    When is the best time to visit Hanoi?

    +

    Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.

    How many days do you need in Hanoi?

    +

    Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.

    Do I book through Outty or through the operator?

    +

    Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
