Koh Tachai is located at the northern tip of the Similan Islands National Park and the latest addition to the coverage of the National Park area along with Koh Bon. Koh Tachai boasts spectacular white beaches and crystal-clear waters surrounding it.

According to National Geographic Society Koh Tachai is due to its remoteness among the top 10 diving destinations in the world. On the island you can trek the nature trail to spot hermits, various reptiles, and Nicobar pigeons. This ancient jungle is full of wonders and mysterious wildlife that is hard to find elsewhere.

What Our Guests Say

★★★★★ 5.0 Google| TripAdvisor| Trustpilot
★★★★★

During our 2 week Phuket vacation we booked 2 tours with private-yacht.com and were really impressed by the warm and friendly manner of the entire crew. The booking process was uncomplicated and well advised, the boats were very clean and well maintained. What particularly impressed me was the passion with which the guides explained details about the country, people, culture and nature. Thailand and Phuket are beautiful, but from the boat they are simply gorgeous.

Did a tour to the Phi Phi Islands via private yacht and it was really top! Communication with the agency was straightforward and my contact Stefan friendly with a pleasant pinch of humor. A lot of emphasis is placed on good service. Personal requests were taken into consideration, sometimes very spontaneously. The crew was super nice and the trip made even more enjoyable. 5/5 can recommend!

Tim L. TripAdvisor
★★★★★

We booked the Jana 43ft sailing catamaran for a private day trip to Ang Thong Marine Park and it was truly the highlight of our stay in Koh Samui. The boat was spacious, clean, and very comfortable. The crew was fantastic — professional, friendly, and extremely accommodating. The views were breathtaking, and we enjoyed a delicious lunch on board. A special moment was on the way back — we caught a fish! Highly recommend this experience.

★★★★★

Incredible day on the water with a fantastic crew! From the first contact to the last wave, everything was perfectly organized. Steven handled all the details, from flexible booking to perfectly timed hotel transfers. The crew was professional, friendly, relaxed and so much fun. If you're looking for an exclusive and carefree catamaran experience in Thailand, this is the place to go. Would absolutely book again.

★★★★★

We booked a private snorkeling tour around the most beautiful islands near Phuket — one of the best family experiences we've ever had. Steve organized everything and made the whole process completely stress-free. The yacht was spacious, clean, and super comfortable. The snorkeling spots were stunning — crystal-clear water, colorful fish, and quiet beaches. Absolutely recommended!

★★★★★

Amazing day boating around Koh Phangan! Great help to schedule the day on yacht. Super helpful to book and prepare schedule and all important things. The crew was amazing. They made everything to ensure our day. Would highly recommend!
