Just book with Kohtours. You won’t regret it.
We did the Angthong Marine Park Tour by speedboat with Kohtours, and it was hands down one of the best experiences of our lives. We were in the Pink Group with Ken as our guide — and honestly, Ken is an absolute legend. He’s without a doubt the greatest single tour host we’ve ever encountered. His energy, humour, and in-depth knowledge of the area made the day unforgettable. Ken kept everyone engaged throughout the day, sharing fascinating history with a hilarious twist, making sure every member of the group felt involved and looked after. He even captured the most incredible photos and videos for us at the top of the national park hike — moments we’ll cherish forever. The whole day was smooth, exciting, and full of beautiful sights — from kayaking through caves to snorkelling in crystal-clear waters. And let’s not forget the Massaman curry at lunch — absolutely delicious! Huge thanks to Kohtours and the entire team. A truly five-star experience from start to finish. If you’re in Samui and thinking of doing a tour, don’t hesitate — just book with Kohtours. You won’t regret it.
Response from the operator: Thank you for your review . Best regards

Never Showed Up and Lied
I have a limited time in Koh Samui and seeing Angthong Marine Park was on my list. I booked to travel to the end on a Wednesday. On Tuesday, I message the company via Viator to ask when they're going to pick us up "tomorrow". They said to wait in our lobby between 7:20 to 7:40 am because the tour started at 8 am. At 7:41am, my lobby concierge calls the tour operator and says that they're picking us up between 8:00 to 8:15 am. At 8:20, I called Viator to complain. Viator basically says that they could not refund because this was a non-refundable. At 8:40 am ish, the company claims that (1) I probably booked the night before and they didn't see the reservation (I did not), (2) they got mad at us and yell on the phone before hanging up on my husband (who asked them to clam down and let him speak), (3) they said that on Monday, I contacted them to cancel my trip date to Thursday (which is not true). After waiting 3 hours (around 9am): me: I am speaking with Viator and they are offering a refund (which they alleged that they could not do without approval from the tour operator). Husband: he is speaking with the tour operator, who is offered a tour the next day and a free pick up to the airport. So basically, Viator offered a refund, which they originally told me that they could not do without speaking to the tour operator. They offered a refund despite never speaking to the tour operator. The tour operator (despite claiming that our booking was for Thursday (it was not)) is offering a free airport pick up. Anyways, it felt like both companies (Viator and this local tour) lied to us. They offered no help to fix the problem. Offered only a refund for a trip that a booked. Both companies are complete trash for alleging that I called and changed the ticket for a different day, offering no apologies, for saying one thing and then some completely opposite in the next moment, and having no accountability. Viator offered no help and instead claimed- we're not the company and just a platform. The tour company said they I changed the date. And basically - this experience has taught me to not trust Viator to hold no accountability for the vendors they recommend us. The tour operator can lie and basically ruin a day of vacation for the limited time at Koh Samui and no one well ever here the wiser. I got a refund for a tour that never picked me up, no apology, and no one fix the issue. Instead, I booked a tour for the next day (Thursday) with my hotel (reliable) and lost $203 dollars for canceling a jet ski tour that I had for Thursday (because I booked at trip for everyday I was in Koh Samui) and now, I am leaving on Friday. Basically, Viator did not refund me for a trip that I had on Thursday because they cannot do refunds (again-no accountability). I had to change the jet ski to a different company so that I could go in the after on Wednesday and have the Angthong trip on Thursday if I wanted to make both trips before leaving Koh Samoi.

Highlight of our holiday
A fantastic day out. So many activities included, both on and off the water. The crew were fantastic, from being unofficial photographers to delivering a tasty, filling lunch. This was a definite highlight of our Koh Samui holiday. From pick up to drop off, this tour was really well organised.

Why this scores 46
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Koh Samui Angthong Marine Park Day Tour with Lunch by Big Boat: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Koh Samui.
How much does Koh Samui Angthong Marine Park Day Tour with Lunch by Big Boat cost?
+
Prices start at $1100 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 Marine Park Day Tour with Lunch by Big Boat take?
+
Plan for about 9 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 Marine Park Day Tour with Lunch by Big Boat worth it?
+
It holds an Outty Ranking of 46 out of 100, which we label "Worth a Look". That score blends traveler sentiment (3.9/5 across 40 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 Marine Park Day Tour with Lunch by Big Boat?
+
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 Marine Park Day Tour with Lunch by Big Boat suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 9-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Koh Samui Angthong Marine Park Day Tour with Lunch by Big Boat?
+
Around 14 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 9-hour experience runs outdoors or after sunset.
Where does Koh Samui Angthong Marine Park Day Tour with Lunch by Big Boat 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.
