Great day trip
Boat was great, I picked over a speedboat so I could see the view and did not disappoint. Having lunch on the boat with the view of the islands was amazing. Breakfast was light- tea, coffee, croissant and banana and lunch was buffet style. They had some vegetarian options too! Hikes were difficult but worth it and snorkeling is not worth it, just swim on the beach or do one of the hikes.
via Tripadvisor
Gorgeous islands, highly recommended.
The tour was great. Must have sunny weather to properly enjoy the view. The boat ride out was about 2 hours and was pretty rough! A lot of people were sick so keep that in mind. The guide talked A LOT and you couldn't understand any of it. A clearer, shorter explanation would probably have been better. Either way I still give it 5 stars because the islands are just so beautiful nothing else really matters.

Beautiful views and long day
Hotel pickup was prompt and our driver was funny. Then we embarked on a 2 hour boat ride where the swells bothered most of the guests and many sick bags were handed out and used. I think the tour guides should have provided ginger ale and ginger snaps as ginger helps many people with sea sickness. The two islands we visited were beautiful. The views of the islands were stunning and my friends and I took many memorable pictures. Getting in and out of the longtail boats on the floating docks was an adventure in itself. I’m a huge snorkeling fan as it’s my favorite hobby, so this was the biggest disappointment for me. This is not a snorkel trip at all whatsoever. Our second stop on a beach with ropes to indicate where to swim, was supposedly where we were to snorkel. It was not a guided tour, we were not by reefs and there were no fish. The water was murky and the top layer had so much trash from tourism, I was shocked. My friends and I hung out in the water a bit to cool off then we sat on the beach and enjoyed the Mountain View’s. Would I go back out to this marine park, absolutely. However, I would go on a speed boat, likely on a private tour, and I would specify that snorkeling is a top priority. This region of Thailand is suppose to have some excellent spots so I will definitely try again.

Angthong National Marine Park Snorkeling Trip By Big Boat From Koh Samui: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Koh Samui.
How much does Angthong National Marine Park Snorkeling Trip By Big Boat From Koh Samui cost?
+
Prices start at $38 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 Snorkeling Trip By Big Boat From Koh Samui 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 Angthong National Marine Park Snorkeling Trip By Big Boat From Koh Samui worth it?
+
It holds an Outty Ranking of 54 out of 100, which we label "Worth a Look". That score blends traveler sentiment (4/5 across 4 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 Snorkeling Trip By Big Boat From Koh Samui?
+
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 Snorkeling Trip By Big Boat From Koh Samui 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 Angthong National Marine Park Snorkeling Trip By Big Boat From Koh Samui?
+
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 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 Angthong National Marine Park Snorkeling Trip By Big Boat From Koh Samui 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.
