This company is absolutely amazing. Their service is so professional, from the facilities and the bathrooms to the transportation. Everything was first class. I thoroughly enjoyed traveling with them and will definitely use them again. They were great.

Lomprayah Speedboat + excellent shuttle service. The staff were very helpful, but allow about 45 minutes for check-in at Koh Tao because there are a lot of people. When booking tickets from Koh Tao to Samui, the ticket stated "Nathon Pier," but upon check-in, my name wasn't found. The staff took a considerable amount of time, calling the Phuket center. When they changed it to "Pralarn Pier," my name appeared. This was quite time-consuming. I wish Klook would provide more detailed pier information on the tickets or vouchers. We almost missed our boat due to the check-in issue. We had to ask staff to help clear a path so my family and I could board. We arrived at the pier 35 minutes early, but still almost didn't make it.

was a bit skeptical because of some of the bad reviews but my experience was flawless for the 28/8/26 full moon festival. Punctual pick up time at 6:00pm at the hotel and was on the boat at around 7pm. You receive a wrist band that you use for your return trip and it’s based on a first time first serve basis. when we arrived back at the pier at 1am we were assigned a colour and a number and groups are sent based on this so there is no pushing and shoving to get onto the boat. the boat departed at about 1:30am. When we got back to Koh Samui, there were drivers waiting to take us back to our hotels as part of the service. Overall good and smooth experience. Waves were a bit choppy on the way back but overall the boat felt safe and life jackets are provided. Highly recommend this service if you want smooth and easy transit to and from the full moon party 👍

Had a leisurely drive around Koh Samui with our reliable driver, Wat. We gave him a list of sights we wanted to visit and he brought us around to those sights except Na Muang Falls (not his fault, it's dry season and he advised it wasn't worth it since can't swim). We had the van all to ourselves which is nice and didn't feel rushed like in a group tour.

Today, 5 of us went on a self-planned island tour. Our driver, Yachtboy, got us to every destination quickly and safely. In between stops, there was always time for a chat to learn more about island life. We saw so much, even off the beaten path of mass tourism. Highly recommended!

Evenings, we still sit there and just say: Wow! That was by far the coolest adventure and the highlight of our vacation.
The quad tour was simply incredible – through water, up and down the mountains, with beautiful views. Everything was explained perfectly, and we felt safe the entire time.
But the best part was the guides, especially Kodi. So friendly, attentive, and motivating! They always made sure no one was left behind. I was really scared of the zipline, but Kodi encouraged me the whole time and told me I could do it. Luckily, I listened to him – it was one of the highlights of the day!
It was also great that the guides took our phone and took photos and videos during the tour. Now we have incredibly beautiful memories of that day.
Many thanks to Kodi and the entire team. You made this excursion unforgettable. Absolutely recommended – our best day on Koh Samui! 🌴🛵⛰️📸✨❤️

Great tour, helps you check off the different landmarks around the island of Koh Samui in just a day! The aircon van is also perfect for a hot and sunny day in Koh Samui to chill while going to the next location! One thing i wished could be improved is more introduction to the history of Koh Samui, I felt that there was very little explaination and wished there was more information about the different places and their rich history. Other than that, a very good tour! Would highly recommend!

Great tour with my guide. The coconut ice cream was good and the pace of tour was good.
Quick facts about Ko Samui
General info
What to know before visiting Ko Samui
Top Ko Samui Attractions
Big Buddha Temple (Wat Phra Yai)
Located on a small rocky island connected by a causeway, Big Buddha Temple features a 12-meter-tall golden statue that shines brightly in the sun. From here, you can enjoy peaceful views of the sea and nearby islands while learning about local Buddhist traditions.
Chaweng Beach
Chaweng Beach is one of Koh Samui’s most popular spots, known for its white sand and turquoise water. It’s perfect for swimming, sunbathing, or joining water sports like jet skiing and paddleboarding. As the sun sets, you can visit lively beach bars, enjoy Thai food, or take a relaxing beach walk under the stars.
Fisherman’s Village in Bophut
In Bophut Beach, you’ll find the charming Fisherman’s Village, a must-visit on your Koh Samui trip. The area is full of stylish shops, restaurants, and cafés set in old wooden houses. On Fridays, the famous night market comes alive with live music, souvenirs, and delicious authentic Thai food—a great place to enjoy the local vibe.
Ang Thong National Marine Park
If you love adventure, take a day trip or boat trip from Koh Samui to Ang Thong Marine Park, a group of 42 islands with vibrant coral reefs and beautiful marine life. You can go kayaking through hidden lagoons, hike to the emerald lake, or snorkel around the reefs.
Secret Buddha Garden
High in the hills of Koh Samui, the Secret Buddha Garden (also called Tarnim Magic Garden) offers a peaceful escape surrounded by lush jungle. As you walk through, you’ll see hand-carved statues of animals, gods, and Buddha figures. It’s a cool and quiet spot that gives you a different side of Koh Samui’s beauty away from the beaches.
Na Muang Waterfall
For a refreshing break, visit Na Muang Waterfall, one of the island’s most scenic natural spots. The area has two waterfalls—Na Muang 1 and Na Muang 2—surrounded by greenery and pools where you can swim. It’s a great stop while exploring Koh Samui, especially if you want a nature-filled adventure.
Tips before visiting Ko Samui
Stay connected with a Thailand eSIM
Before your trip, get a Thailand eSIM on Klook so you can easily use maps and translation apps and book activities online. It’s cheaper and more convenient than buying a local SIM card after you arrive.
Choose the right season to visit
The best time to visit Koh Samui is from December to February for cool, dry weather, or from March to June if you love sunny beach days. Avoid heavy rains between October and November unless you prefer a quiet getaway.
Pack light but smart
Bring breathable clothes, sunscreen, and a hat—it’s warm and sunny most of the year. If you plan on exploring Koh Samui’s temples like Wat Phra Yai or Wat Plai Laem, pack modest clothing that covers your shoulders and knees.
Book activities early
Popular tours like Ang Thong Marine Park or island hopping to Koh Tao and Koh Phangan can fill up fast. Booking ahead on sites like Klook ensures you get good prices and guaranteed spots for your favorite adventures.
