Ang thong marine park day trip
Great day out. Well organised. Wear decent shoes if you’re going to do both view points. Both are excellent the second is longer but views are worth it. Kayaking & snorkelling good fun. Sit at the back of the speedboat if you would prefer a smooth ride. Lunch is ok. Options to buy drinks & snacks at the first viewpoint stop, lunch(2nd viewpoint) & kayak stop. Pick up and comms very good.
Response from the operator: Dear Julie, Thank you so much for your wonderful 5-star review! 😊 We’re delighted to hear that you had a great day exploring Angthong National Marine Park and that you found the trip well organised from start to finish. Your helpful tips about wearing good shoes for the viewpoints and sitting at the back of the speedboat for a smoother ride will be very useful for future travelers. We’re also happy that you enjoyed the viewpoints, kayaking, snorkeling, and our pickup and communication service. The breathtaking scenery of Angthong is truly special, and we’re glad it made your day memorable.

Great Speedboat to Ang Thong
We had a fantastic time on this tour! The snorkeling spot was amazing. The waters were a bit market when first getting out of the boat, which makes sense because we docked with two other boats. Afterwards, near the cliffs the coral and sea life came alive! The hike on the main island was no joke, but so worth it! The monkeys were a sight, as well as the crystal clear water. We ran into a bit of weather when heading to lunch, but the crew handled it so well. We did eat lunch with a couple other tours, so the line to get food was long (just wanted to note that). We chose not to kayak due to it raining some, and just enjoyed the second island. The last stop was the emrald lake, which was cool to see. You can’t get in the water and the hike up the stairs was scary, but worth it! Coming back was rough but nothing too bad. I don’t think the boat was too packed. My companion and I chose to sit at the front, which was awesome because you had views and fresh air. Inside looked more cramped but manageable. The crew was also phenomenal!! Highly suggest booking this to see Ang Thong.
Response from the operator: ⭐⭐⭐⭐⭐ Thank you so much for your wonderful review! We're delighted to hear that you had a fantastic day exploring Ang Thong Marine Park and enjoyed the snorkeling, breathtaking viewpoints, Emerald Lake, and the beautiful scenery along the way. 🌴🐠💙 We're especially pleased to know that our crew took good care of everyone despite the changing weather conditions. Thank you also for sharing your helpful insights about the lunch stop and hiking trails for future travelers. We truly appreciate your recommendation and hope to welcome you back for another unforgettable adventure in Koh Samui soon! Best regards, Tony & the Backpacker Samui Travel Team Koh Samui, Thailand

Great day excursion, trip highlight
The pickup was clear and on time, the tour team was competent and upbeat, and proactively helpful with helping us take pics and get on and off the boat. The value was good, in terms of the number of different stops and activities. The buffet lunch was delicious and home cooked. The rainy season meant the water wasn’t crystal clear for snorkeling, but we still enjoyed it. Note that the hike to the viewpoint is quite sweaty and strenuous- but worth the views!
Response from the operator: Thank you very much for sharing your experience on the Angthong National Marine Park tour. We’re really happy to hear that you enjoyed the day overall and that our team made the trip smooth, punctual, and helpful throughout the journey. It’s great to know you appreciated the variety of stops, activities, and the home-cooked buffet lunch as well. You’re absolutely right about the rainy season conditions affecting water clarity for snorkeling, this can vary depending on the weather, but we’re glad it didn’t take away from your enjoyment of the day. And yes, the viewpoint hike can be a bit of a challenge in the heat, but the panoramic view is usually worth every step! We truly appreciate your helpful tips for future guests, and we hope to welcome you again for another adventure in Koh Samui. Best regards, Tony & the Backpacker Samui Travel Team Koh Samui, Thailand

Super nice but crowded
I really enjoyed this day. We made multiple stops and were well informed at every point about timings, the plan, etc. The staff on board were great and the communication prior to the trip was also great. They make sure you have water at all times and offer snacks throughout the day as well as including a delicious lunch. However, the one place this tour is let down is the amount of people on the boat. There were so many people all crammed in. You had to sit very uncomfortably for up to an hour at a time. Everyone was wet from being in and out of the water and you were literally squished in. (And lots of people stank). This one reason would probably not make me take this tour again.
Response from the operator: Thank you so much for your review and for joining our Angthong Marine Park tour. We’re very happy to hear you enjoyed the trip, the stops, the food, and the service from our team. Your kind words mean a lot to us. We also truly appreciate your honest feedback regarding the boat feeling crowded. We understand this can affect comfort, especially after swimming stops, and we’re sorry for the inconvenience. Your comments are very valuable and will be shared with our team as we continue working to improve the experience. Thank you again for spending the day with us, and we hope to welcome you back to Koh Samui in the future. Best regards, Tony & the Backpacker Samui Travel Team Koh Samui, Thailand

We really appreciate you joining us and hope to welcome you back on another adventure soon! Best regards, Tony & the Backpacker Samui Travel Team Koh Samui, Thailand

Why this scores 67
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Koh Samui: Angthong National Marine Park 42-Island Speedboat Tour: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Koh Samui.
How much does Koh Samui: Angthong National Marine Park 42-Island Speedboat Tour cost?
+
Prices start at $65 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Koh Samui usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does Koh Samui: Angthong National Marine Park 42-Island Speedboat Tour take?
+
Plan for about 8 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 Koh Samui is not rushed.
Is Koh Samui: Angthong National Marine Park 42-Island Speedboat Tour worth it?
+
It holds an Outty Ranking of 67 out of 100, which we label "Solid Choice". That score blends traveler sentiment (4.7/5 across 19 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Koh Samui, and how flexible the cancellation terms are.
Can I cancel or reschedule Koh Samui: Angthong National Marine Park 42-Island Speedboat Tour?
+
Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.
Is Koh Samui: Angthong National Marine Park 42-Island Speedboat Tour suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 8-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Koh Samui: Angthong National Marine Park 42-Island Speedboat Tour?
+
Around 7 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 Koh Samui 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 Koh Samui and add a light layer if any part of the 8-hour experience runs outdoors or after sunset.
Where does Koh Samui: Angthong National Marine Park 42-Island Speedboat Tour 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 Koh Samui 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 Koh Samui?
+
On Outty we rank every Koh Samui experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Angthong National Marine Park VIP Small Group Tour, Cooking Class in Koh Samui with Micro Organic Garden, Half Day Elephant Home Sanctuary in Samui. 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 Koh Samui?
+
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 Koh Samui?
+
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.
