I definitely recommend Andaman. My wife and I were on a four day trip (13 dives). It was unforgettable. The Similan Islands are a great place to dive and the Andaman team did everything to make the most of this place. The ship was clean and comfortable, nice atmosphere and delicious food. All diving equipment is in excellent condition. A team of professionals who are ready to answer any of your questions. The trip went perfectly without any disruption to the schedule and any complications.
Visited dive sites: Surin Islands, Richelieu Rock, Koh Tachai, Koh Bon, Similan Islands on a 4 Days / 4 Nights Liveaboard Trip in Thailand.
