2-Hour Koh Samui ATV Quad Tour

dominiqueet, Sep 2026

A must do!

Start to finish this tour was amazing! Pick up was prompt (they gave us 30 min time frame but was there from the start time) It was pretty much a private experience as we were one of two couples which I felt was better as the guides stopped and managed to take pictures and videos of us. The best ATV experience ive ever done, it was really challenging and the route was very long! Stopped off for 30 mins at the tree top cafe so if youre not doing zip lining but want to see the amazing views this is definitely worth doing. They also look after your belongings and give you a water proof bag for the valuables which was a helpful touch. Would recommend using water shoes or trainers you dont care about as we went through alot of muddy water :) 1000% recommend this trip.Thank you :)

Great family day in Koh Phangan

We stay in Koh Samui with our family in July and this was one of the best days of our holiday. The boat was very nice and not crowded because it was only for us. The crew was friendly and always smiling. They take us to nice snorkeling spots and also to a quiet beach that you can only reach by boat. The water was so clear and the kids really enjoyed it. Lunch cooked by the chef was fresh and very good. We never felt rushed and the whole day was relaxed. Thank you to all the crew for making our family trip so special. We hope to come back next time we visit Samui.

Semi-Private yacht adventure to Ang Thong Park’s hidden treasures

Romeo_T, Sep 2026

Don’t hesitate, just book it!!!!

Worth every single penny. Everyone on staff was extremely kind, helpful, and very motivating to have the best time possible. Value the conversation and company of the boat crew and felt taken care from start to finish. This was the most worth it tour I have ever taken on any vacation I’ve ever been on. Thank you for making this the highlight of our entire trip.

Amazing diving experience in Koh Toa from Koh Samui

Very professional organisation, with safety first, good supervising and instruction, nice diving spots and explanations about what to see, underwater life. Very good diving instructor, good food on the boat, transfer from the hotel etc. Everything organized online directly with Discovery Dive Centre.

Sail rock - amazing

I recently did the 2 dive trip to sail rock, I can’t recommend it enough. My guide Pierre was amazing and super nice, he made the trip feel safe and also very very fun, there was a good briefing at the start and time to get to know your group you are diving with. The lunch on board the boat in between dives was fab. 10/10 !

Koh Samui 2-Dive Trip to Sail Rock for certified divers

F4110GLmarciac, Aug 2026

Best diver ever!

If I could give this place double the stars, I would. I hadn’t logged a dive in maybe 8 years before today and I was a little anxious, especially with the chop at sail rock. He calmly talked me out of my worries and made me feel so comfortable. We did a simple refresher then had two great dives saw barracuda, angelfish with purple stripes and many I don’t know. It was fascinating and good to be down again thanks to the great assistance from Discovery!

It was a great experience to do the Open Water Diver Course with DISCOVERY, Our guide Jo was great character, very experienced and a good teacher. Everything else worked very well starting from the hotel pick up to the boat and the great Thai food served on the boat.

Real off-road adventure – demanding, fast-paced, and brilliant!

The quad tour was absolutely exciting, technically demanding, and exceeded my expectations more than I could have imagined. Exactly the right adventure for anyone looking for a real challenge. The tour is definitely not suitable for children. I would book it again anytime!

Mr. Tu Day Trip to Angthong Marine Park by Speed Boat from Koh Samui

525mazd, Aug 2026

Enjoyable family day out

Lovely day out. The stops were really good, a little rushed in places but the whole trip worth the experience. In hindsight the boat ride was a little much for a 4 year old but overall a great adventure and our active 12 year old is still raving about it.

Private Yacht Charter in Koh Samui with Chef”

joelwG1591XP, Aug 2026

Perfect day cruising the Gulf of Thailand

While of course the beautiful 52-foot perfectly-finished boat and the location, the stunning Gulf of Thailand, already make the perfect experience for incredible memories which will last a lifetime, the fantastic hospitality from Captain Luca and his amazing crew really make this 100% guaranteed the best experience you could ever have on your vacation. Their warmth and sincerity (and the prosecco they serve) really completed the perfect day. **Bonus tip: to my complete surprise, if you have some Zucchero numbers queued up in your playlist that will completely take the experience over the edge!

Wonderful relaxing trip

Lovely experience and only 30 other guests in the boat. Staff could not have been more welcoming and helpful. Food lovely and plenty of it. Boat not glamorous so don’t expect everything to be perfect and shiny but just what is needed for visiting the area around Samui.

Koh Samui Jungle Kitchen – Evening Cooking Class (max 8 guests)

m3000, Aug 2026

Our Teenagers Loved It!

We spent 3 weeks in Asia and this was literally the highlight of the entire trip for our teenagers. You get a tour of all the different plants you'll be using in the dishes you'll be eating, and then make several dishes that then all taste amazing.It does take a bit until you actually eat, but the area you'll be cooking in is gorgeous and it was so much fun. Made some red duck curry, fried chicken, fish, and Pad Kra Pao. And get the recipes afterwards. Water is free and beers were 100 baht a bottle while you cook.So if you're looking for a cooking class on Koh Samui then I'd highly recommend it. It's a bit pricey but worth it.

Koh Samui Custom Sightseeing Tour with Private Guide

kitty_knows, Jul 2026

German tour, super fun, saw everything and more, family-owned

We booked the German guide as one of us spoke no English. It was so enjoyable and we had such a good time. The private guide / driver option is so much better and well worth every penny. You don’t have to wait for random people coming back late to the bus or taking a million selfies. You can just get on with what you are interested in. We were three ladies in the end (2 guests and one guide) and it made for a real fun day out. We saw everything we had intended to see and more. The company Mr Samui is family-owned and it was a pleasure being their customer and being looked after (proper Thai hospitality). Next time we go to Samui we will definitely choose them again.
