Snorkeling with manta rays
Where to snorkel with manta rays in Thailand
The most common place for sightings is Koh Bon which has always been the best place, it’s where the mantas come to be cleaned. They are also being seen at Koh Tachai. Both Koh Bon and Koh Tachai islands are within the Similan Islands national park which is open to boats from November to April. The best months for manta ray sightings are January to April.
We do not have snorkeling day trips to going to Koh Bon or Koh Tachai, you can only get there by liveaboard.
Manta rays can also be seen at the more northern Similan dive sites, around the big granite boulders, but only the dive boats go there.
The same is true of Racha Noi, Hin Daeng and Hin Muang which are all dive sites south of Phuket. They are not places for beginner snorkelers so it can be hard to find a suitable boat.
