The trip to Ant Tong National Park was really disappointing. The speedboat ride was torture. The boat was so crowded that the crew had difficulty seating everyone and people were sitting too close to each other in a terrible crowd. The boat's three engines were very noisy, especially for those sitting next to them. The skipper sailed at a tremendous speed despite the waves and there were terrible jumps during the cruise. The boat's crew was really good in terms of treating the passengers, but the conditions on the boat were unbearable. Maybe a big, slow boat would be better. Because the boat is closed, you can't see the view while sailing, and on this particular cruise, you couldn't stand because of the difficult sailing conditions and the heavy load on the boat. I just waited in anticipation for this day to end.

Thank you for sharing your feedback with us. We are glad to hear that our crew took good care of you, but we are truly sorry that the boat ride itself was uncomfortable.
High speedboats are designed for faster travel, but when sea conditions create rough waves, the ride can definitely feel bumpy and noisy near the engines. We strictly observe official passenger capacity limits on all trips, but we understand that a full boat combined with rough seas made the journey feel crowded and difficult to enjoy.
Your point regarding boat types is very valid—for travelers who prefer a smoother, more spacious, and slow-paced journey with open views, our big boat options are indeed a much better fit. We appreciate your honest review and will use your feedback to help future guests choose the best vessel for their comfort.

Disappointing experience
I joined the tour with my wife and 2 children - ages 10 and 6.
We were generally disappointed with the experience.
Firstly, the itinerary we received said we would begin with a light breakfast. All we were offered was tea and coffee. This meant we began the day feeling hungry. We were also told there would be fruit on the boat - which there wasn’t
Our first stop was snorkelling in a coral reef. We were told we may need water shoes to protect our feet. We felt compelled to take 4 pairs and were only told afterwards they were 1200 baht. There was no mention of needing these in the description of the tour.
The reef felt like a boat yard, with probably 100 other snorkellers. And all the coral was dead. Our tour guide told us this was because so many other tourists had been before, and killed it. This is sad. I think a reputable company like Insea should be more concerned with conserving wildlife they are showcasing.
We then moved onto Ko Mae Ko to climb a viewpoint and snorkel. Our guide gave us no information about how to manage our time. We began the viewpoint climb and came nowhere near the top, before returning and having almost no time left to do any kayaking. It felt very rushed. The guide could have advised us about which of the viewpoints to aim for with kids. And then what time we should turn back to ensure we still have some time to enjoy the kayaking element.
At some point the captain decided to rearrange with schedule without telling us. So the lunch stop was pushed back to 3pm. Our children were crying with hunger, but we moved onto to Ko Wua Ta Lap.
Again we were given no advice about what to do there. So just sat on an extremely congested beach. We gave up and had to buy some ice cream for our kids as they were too hungry to do anything else by this point.
Finally we were taken to the lunch stop at about 3pm (the itinerary we received said this would be 12.30-1.30pm). We were collected from our hotel at 7.30am so our children had not eaten for over 7 hours.
We then returned back to Samui.
Finally I would add that our taxi driver to return us to our hotel drive very dangerously. Lots of heavy acceleration and braking, and beeping the horn. We’ve been in quite a few taxis in our visit to Thailand and Samui, and this was the least safe we’ve felt.

Thank you for your detailed feedback. We have reviewed the points raised with our team and would like to clarify a few matters.
Breakfast: We provide a light breakfast at the pier, including tea, coffee, Ovaltine, bread, fried dough, and jam. Fresh fruit is served at the restaurant rather than on the speedboat due to hygiene considerations.
Water shoes: These can help prevent injuries around rocky or coral areas. K Sea Speedboat does not sell water shoes. At the snorkeling site, other operators may sell them, and our staff only assisted in making an inquiry on the guest’s behalf.
Snorkeling crowd: This is currently high season, and the snorkeling areas designated by the national park are limited. Many tour operators visit around the same time, so some areas can become crowded. The park also closes annually from 1 November to 15 December to allow the ecosystem to recover.
Itinerary changes: The order of activities may be adjusted according to weather and sea conditions, with safety as our priority. At around 11:30 AM, winds suddenly strengthened, so the captain adjusted the itinerary due to expected stronger winds and waves along the route from Koh Wua Talap to Koh Phaluai.
Activity guidance: Guides normally advise guests who wish to enjoy all activities to visit the viewpoint only up to Level 3, allowing enough time for kayaking. However, we acknowledge that clearer guidance should have been provided, especially for families with children, and we will reinforce this with our guides.
Return transfer: We spoke with the driver, who explained that a motorcycle suddenly cut in front of the van, requiring sudden braking and the use of the horn. We understand this may have been uncomfortable and will remind our transfer team to drive with extra care and prioritize passenger comfort and safety.
We sincerely appreciate your feedback, as it helps us identify areas where we can improve our service and communication.

Family visit on speedboat to Ang Thong marine park
We had a brilliant experience on the speedboat to Ang Thong marine park. We travelled as a family of four with two adult children and visited several islands and had time for snorkelling as well as a stop for lunch. Water and soft drinks (cola) provided throughout the day as well as snorkel equipment. Everything was clean and there was plenty of space on the boat, we even had chance to sit salt the font of the boat as well travelled which was a very special experience. The whole team on our boat were informative, friendly and looked after us well. I would highly recommend.

Trip ruined by loud music
We took our kids out to see the national ocean park which was very nice however the speedboat journey was ruined by having to listen to extremely loud party style music..no one
On the boat showed any enthusiasm to get up and party which the rep was trying her best to achieve..
It's not a 18/30 booze cruise if I had know this was going to be the way we traveled I wouldn't of booked it..
At very least there should be a show of hands at start asking for or against loud music even my teenage kids though it was not a great way to travel
Think hard before you book the music is loud and not for us
事業者からの返答
Thank you for your review. We are delighted that you and your kids enjoyed the beautiful national marine park, but we offer our sincerest apologies for the overly loud music during your speedboat trip.
We aim to provide a fun and engaging atmosphere, but we completely understand that a "booze cruise" vibe is not what families book us for. We apologize that this detracted from your experience. Your suggestion to check in with passengers about music preferences is fantastic, and we are sharing this with our operations team to establish better guidelines for on-board music and volume control. We appreciate your helpful feedback and wish you and your family safe travels!

Just OK
Everything was fine, but there were just too many people. When we got to the snorkelling stop it was like a washing machine. The only other-significant downside was at the lagoon. There was a noisy generator about 20 feet from the beach which ruined a very peaceful spot.

Not a good day out
34 of us packed onto a small boat barely any space. I gave up my seat for a family inside so had to sit outside at the front of the boat. They were going way to fast and I was flying off the seat constantly. I felt a big crack in my back and neck. I was visibly hurt so they made space for me inside but still didn't slow down. I dive I've been on so many boats and never experienced this and it wasn't even a rough day. I have been in agony since and have had to go to physio at home with whiplash, left me in pain all holiday. At the end of the day the tour guide (boat 4) then had a rant at all of us because he didn't get the tip he wanted which made everyone really uncomfortable. Very weird experience!

Thank you for taking the time to share your experience with us.
We are truly sorry to hear about what happened during your tour. Your safety and comfort are our top priorities, and it is very concerning to learn that you felt unsafe and were injured during the trip. This is absolutely not the standard of service we aim to provide.
We sincerely apologize for the overcrowding on the boat, the speed of the journey, and the lack of proper care after you were visibly hurt. We are also very disappointed to hear about the guide’s behavior at the end of the tour, which is completely unacceptable and does not reflect our company values.
Please note that we do provide accident insurance coverage for all customers joining our tours. In cases of injury, we kindly ask that this is reported immediately to our guide on the day of the trip so we can assist you promptly and take full responsibility where appropriate. Unfortunately, we are unable to process such cases if they are not reported on the same day.
At the same time, we have checked internally and, so far, have not received similar reports from other customers on the same trip. However, we take your feedback very seriously and are currently investigating this matter with our team and the crew of Boat 4 to ensure that appropriate actions are taken.
We are truly sorry that this experience affected your holiday and caused you ongoing pain. If you are open to it, we would appreciate the opportunity to follow up with you directly.
Thank you again for bringing this to our attention.
