Strong oil pollution of the Angthong Marine Park during day trip!
The boat leaks huge amounts of heavy black oil into the sea! But you should only use reef-safe sunscreen for snorkeling?

Long Day but Worth It
I probably would actually give this 4.5 stars, if it allowed me to. The only reason I did not give it 5 stars was because the description wasn't exactly accurate. Here is how the day goes... The pick up from the hotel was smooth, about a 30 minute trip to the port. Get on the boat and there was coffee, muffins, bananas and cereal waiting for us, that was nice. About 80-100 people on the boat. Then we head to the Marine Park. It's a 2 hour boat ride. Honestly, I guess your only other option would be to pay more and take a motorboat but considering I paid less than 40 bucks, this was worth it. Just bring a book or something to watch on your phone during the long boat rides. Once you get to the first island it's a 500m climb to the top. it is not mandatory, but well worth the effort. By the time you are at the top, you are tired and sweating big time. The hike to the top and down takes a good hour. You have about 30 minutes once you come down to take a dip in the beautiful ocean. Then lunch aboard the boat at 12:15pm. It was quite good actually, 2 types of chicken, rice, some veggies and watermelon. Then about a 20 minute boat ride to the second island. Get there around 2pm Time for kayaking. It's around a leisurely 30 minute kayaking journey in the most beautiful of settings. You end on a cute beach and have about an hour to swim, snorkel (although no fish to be seen), take a hike and see a lagoon or just buy a coconut or ice cream and chill. At 3pm it is back on the boat for the 2 hour ride back to Koh Samui. Once you get back to port, your driver was waiting to take you back to the hotel. From pick up to drop off, it was just over 11 hours. Long day but enjoyable.

It's good experience...
It's good experience overall but a bit rushed if you are with family and not very fit especially for the hike in the hot sun. It is very well managed with activities and good food as well as very courteous staff
via Viator
No fish in the Sea
The food was Great for the price but the experience with the Island hopping were less so. Not being able to swim when arriving on an Island for example and it was very hot.
via Viator
Terrible trip
It was a really long trip to the national park, just to climb a steep hill to a viewpoint. Really good views from the top but the climb was hard and not for the feint-hearted. The snorkeling was terrible (or rather - non-existent). The water was filthy from all the boat debris and it was very shallow. The coral was dead and broken. It was far too difficult to see anything, probably there are no good fish that would be found in that over-traded dirty snorkeling area. The beach area was incredibly small. The staff on the boat were friendly and inviting but the trip was a waste of a day.

Why this scores 55
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Angthong National Marine Park Tour by Large Boat: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Koh Samui.
How much does Angthong National Marine Park Tour by Large Boat cost?
+
Prices start at $39 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 Angthong National Marine Park Tour by Large 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 Angthong National Marine Park Tour by Large Boat worth it?
+
It holds an Outty Ranking of 55 out of 100, which we label "Worth a Look". That score blends traveler sentiment (3.8/5 across 44 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 Angthong National Marine Park Tour by Large 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 Angthong National Marine Park Tour by Large 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 Angthong National Marine Park Tour by Large Boat?
+
Around 15 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 Angthong National Marine Park Tour by Large 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.
