The 15 Best Snorkelling Trips in Thailand

Koh Tao for reliability, the Similans for the best water, the Krabi islands for convenience. These 15 trips are priced with the gear, and honest about how deep the coral sits and how crowded each stop gets.

Koh Samui: Pig Island & Koh Tan Snorkeling by Speed boat

1.Koh Samui: Pig Island & Koh Tan Snorkeling by Speed boat

★★★★★★★★★★4.5 · 4,149 reviews · 4 hours · from $52Our pick

Visit Koh Madsum, better known as Pig Island, with guides such as Sun, Joe, Cola, and Alex. You’ll have time for photos, swimming, and feeding the pigs, then snorkel near Koh Tan before a Thai buffet lunch. Short boat rides make this a good choice if you want island scenery without spending half the day at sea.

“Was advised not to snorkel due to murky waters but water was still clear enough. Nice food at buffet although small selection & pig island is definitely worth the visit!”

I did feel sorry for the turtles - we were told not to swim above the turtles or too close to them, but I felt people swarmed the turtles and got way too close to them, all for a photo! Just be mindful not to get too close!!”

★★★★★★★★★★4.6 · 1,244 reviews · 4 hours - 390 minutes · from $51

Start early from Tonsai Pier with an English-speaking guide such as Batman, Matt, or Birdy, depending on the boat. You will visit Maya Bay, Pileh Lagoon, Monkey Bay, Viking Cave, and several snorkeling sites. Choose the half-day trip for the main sights or add Bamboo Island, lunch, and extra swimming with the full-day option.

“Brilliant day from start to finish. Matt was friendly and helpful, probably the best guide we’ve ever had. Plenty of fresh pineapple and bottled water/Pepsi on board the speedboat, which was smoothly and professionally driven. The entrance fees to Maya Bay were included, as well as Bamboo island, which made for a very reasonably-priced tour. If anything, the lunch of chicken and rice was a bit lacklustre, but the cafe on Bamboo island had loads of decent options if you had a fussy member of your party! Really great tour overall, would definitely recommend it, and it is 100% worth getting up early for!”

The beach was lovely to relax and chill before heading back. Was a perfect experience for us who didn’t want to get off at every island and didn’t want to spend the whole day doing an excursion.”

Our guide Pichi (Peachy?) was full of energy and spoke great English. The sunset was incredible, the activities were spaced out nicely, the food was delicious. We swam with the bioluminscent plankton under the stars. Just magical. I obviously highly recommend this tour.”
