What you'll see and do
Begin your journey at the southwest of Koh Samui where we will pass the picturesque Five Islands. These islands are home to a mysterious and rarely seen phenomenon, the harvesting of bird`s nests.
Pass by without stopping
Our first stop in the Ang Thong Marine Park archipelago is also the most remote and magical spot, exclusive to our tour. Go for a guided sea kayaking tour along the coastline to explore the dramatic cliffs, limestone islands, caves, magical tunnels, as well as a secret lagoon. Alternatively, hop on our dinghy that accompanies the kayaks.
60 minutes here
Sail north beyond the Marine Park waters, to Koh Wao, where you will find the best snorkeling sites.
Pass by without stopping
Sailing further north we will reach the Ko Wao island group, which offers some of the best sites to explore the vibrant tropical reef. It's considered one of the top 20 snorkeling sites in Thailand. We're the only non-speedboat vessel to reach this destination. We'll select the optimal site depending on conditions, to ensure you have the best underwater journey possible. After a short safety briefing, our crew will fit you with complete snorkeling gear, and take you on a guided underwater tour, to see some amazing marine life. Non-swimmers and young children are welcome to get into our netted floating raft, which allows you to see the tropical reef from the safety of a raft.
60 minutes here
We head back to the marine park and will pass Ko Lao Yu to enjoy the scenery. At this point, we will offer you a delicious buffet lunch while you journey along Ang Thong park`s most interesting limestone islands, which rise from the sea as dramatic rock cliffs and bizarre rock formations.
Pass by without stopping
Koh Thong Thaeng is one of the bigger islands in the Marine Park, and a beauty to behold.
Pass by without stopping
Next, we pass Ko Wa Noi on our way to Ko Mae Ko to see the Blue Lagoon.
Pass by without stopping
As we head south, we will also pass Ko Sam Sao or three sister island, with its notable natural stone bridge that extends out into the sea, with clean white sandy beaches.
Pass by without stopping
Ko Mae Ko is where you will find the famous "Blue Lagoon", the inspiration for Alex Garland's book and later movie, "The Beach". Also known as the "Emerald Lake", locals call it "Talay Nai", which means "inside sea" and it is widely considered the highlight of the Ang Thong Marine Park. We are the last boat allowed to visit Ko Mae Ko, which means that we do not meet other organized tours.
15 minutes here
Blue Lagoon Emerald Lake
Here you can decide to climb up to the viewpoint or relax on the secluded beach. Climb up the steep stairs along narrow ravines to reach a panoramic view of the Park's 42 islands. Once we've reached the top, you will venture to the other side to take a closer look at the hidden saltwater lake completely enclosed, which besides its beauty, also acts as a natural nursery for all sorts of marine life.
45 minutes here · Admission not included
Ko Wua Ta Lap
As we head back to Ko Samui, we will also pass Ko Wua Talap, the Marine Park headquarters.
Pass by without stopping
Cruise past Phaluai Island, one of the few inhabited islands in the Ang Thong Marine Park, home to a small community of "sea gypsy" fishermen, which are the original people that settled in the Samui archipelago. Enjoy the scenic cruise back to Ko Samui, cool down with a few drinks and a banana split on the deck, or take a dip in our jacuzzi. On most days you will embrace wonderful views of the sunset that will remain with you for a lifetime.

Amazing Day at Ang Thong Marine Park
A fantastic experience exploring the hidden treasures of Ang Thong Marine Park! We really appreciated the relaxed pace of the trip, with plenty of time to enjoy the beautiful scenery and simply unwind during the cruise. The highlights were definitely jumping into the crystal-clear water straight from the yacht and kayaking through the spectacular surroundings. A perfect combination of adventure and relaxation, and a wonderful way to experience Ang Thong!

Good experience,...
Good experience, beautiful islands, nice atmosphere and vibe. It’s not ‘private’ or ‘semi-private’, we were about 20-25 people on board, but the trip itself was good.
Response from the operator: Thank you, Zeev, for taking the time to share your feedback. We’re pleased to hear that you enjoyed the beautiful islands, atmosphere, and overall experience with us. We would, however, like to clarify the meaning of our Semi-Private tour for future guests. The Red Dragon is a large 78-foot yacht, and we intentionally limit the number of guests on board to a maximum of 28 to provide significantly more space and personal service than conventional large-group tours. When we have more than 20 guests on the Red Dragon Yacht, two guides lead the activities to provide a more personal service. Our semi-private concept is not intended to mean a private charter. Rather, it combines the comfort and facilities of a large yacht with a deliberately limited number of guests. Our boats, facilities, and activities are designed to provide plenty of room and a nice balance of adventurous activities and relaxation in between. Another important part of our semi-private experience is what happens once we reach the islands. Our tours are carefully timed to avoid the peak hours when most other boats arrive, helping our guests enjoy kayaking, snorkeling, and the Marine Park’s most scenic locations with fewer people around — making the experience feel more personal, peaceful, and exclusive. Thank you again for joining us, Zeev. We’re glad you enjoyed the trip and appreciate the opportunity to clarify what we mean by our Semi-Private Ang Thong experience. Aom

Amazing day of activities!
We had such an amazing day on this excursion! We went kayaking, snorkeling, and did a short hike, but the snorkeling was definitely the highlight for me. Our snorkeling guide stayed with us the entire time and pointed out so many beautiful fish and sea cucumbers that I probably would have missed on my own. The boat crew was incredible from start to finish. They took the time to learn everyone’s names and made sure to take pictures of everyone throughout the day, which made the experience feel so personal. Most importantly, they made me feel completely safe and comfortable, especially while snorkeling, which I really appreciated. The food that was included was also surprisingly delicious! Overall, this was such a fun, well-organized, and memorable experience. The crew truly went above and beyond to make sure everyone had a great day. I would absolutely recommend this excursion!
Response from the operator: Thank you so much, Andrew, for your wonderful and detailed review! We’re delighted to hear that you enjoyed all the activities, and especially the snorkeling. Our guides are always available to help guests feel safe and confident in the water, and we provide all top-quality equipment for your comfort and safety. Having your guide stay alongside you and point out the beautiful fish, sea cucumbers, and other marine life is exactly the kind of personal experience we want our guests to have. It also means a lot to hear how much you appreciated our crew remembering everyone’s names and taking photos throughout the day. Our crew is delighted to provide a warm, attentive, professional service to ensure every guest is safe and comfortable throughout the journey, whether guiding a kayak, snorkelling, or climbing to the viewpoint. Those personal touches are an important part of making the experience feel special rather than simply another group tour. And we’re especially happy that the food surprised you! We pay great attention to dining during our tours. Our chefs prepare all of the food during the tour from scratch, sourcing local ingredients to provide our guests with fresh and delicious food. We firmly believe that good food and drinks are an important part of providing an all-around outstanding experience. Thank you again for your recommendation, Andrew. Knowing that you felt completely safe, comfortable, and personally looked after while having such a fun day means a great deal to our entire team. We hope to welcome you aboard again on your next visit to Koh Samui! Aom

We believe these details, together with our small group experience, allow our guests to truly relax and enjoy the beauty of the day without the crowds. Thank you again for choosing to sail with us.

Why this scores 96
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Semi-Private yacht adventure to Ang Thong Park’s hidden treasures: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Koh Samui.
How much does Semi-Private yacht adventure to Ang Thong Park’s hidden treasures cost?
+
Prices start at $131 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 Semi-Private yacht adventure to Ang Thong Park’s hidden treasures take?
+
Plan for about 10 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 Semi-Private yacht adventure to Ang Thong Park’s hidden treasures worth it?
+
It holds an Outty Ranking of 96 out of 100, which we label "Peak Performance". That score blends traveler sentiment (4.9/5 across 902 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable most popular in Koh Samui, and how flexible the cancellation terms are. Scoring 90 or above puts it in the Outty 90+ Club, the top tier of everything we rank.
Can I cancel or reschedule Semi-Private yacht adventure to Ang Thong Park’s hidden treasures?
+
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 Semi-Private yacht adventure to Ang Thong Park’s hidden treasures suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 10-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Semi-Private yacht adventure to Ang Thong Park’s hidden treasures?
+
Around 316 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 10-hour experience runs outdoors or after sunset.
Where does Semi-Private yacht adventure to Ang Thong Park’s hidden treasures 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.
