Comprehensive and concise day trip to cover main attractions on the island.
Reviews: Private Customized Tour with Driver in Koh Samui

It was great, with an 8 hours private driver we were able to visit all attractions we were willing to, in our pace and with comfort. I would recommend.

It was a decent tour, but its main drawback was probably the price; I wish it were cheaper. We were picked up from the hotel on time, then driven around half the island to pick up the others—the Chinese are very unpunctual, and we had to wait a long time. We were taken to the pier, given water and buns, and loaded onto a speedboat for about 30 people. The ride to the first spot took about an hour and a half. Along the way, they offered free water and soda, and also sold beer and swim shoes. The place is very beautiful; I even saw a turtle! But there was a lot of trash in the water... Then we were taken to the second spot, and then to lunch. The lunch was meager, but oh well, we didn't go there to eat. After that, they dropped us off at a beautiful beach for a couple of hours, but be careful—the sun is very strong. The ride back also took about an hour and a half, plus transfer to the hotel. Overall, I can recommend it!

It was a fantastic experience from beginning to end. Everything was perfectly organized. The explanations were excellent, we saw incredibly beautiful islands, and enjoyed some great activities. Everyone was friendly… I can't find a single bad thing to say. 10/10 points! TOP TOP! Thank you, Boat 19! 😁👍🏻
