“Another amazing day! Very modern boat and crew were very helpful and as previous tour with “happy Samui” they are all as name suggests. We had booked for later in day but Viator rep James, advised of poor weather for our planned time and offered refund or change of time, thankfully was able to accommodate earlier session and weather was perfect as were the stunning islands we visited, and as for the pigs, well cuteness overload! So many piglets and amazing to get so close to all the lovely piggies inhabiting! I to next island and a lovely lunch provided, highly recommend this trip!”

“Went with a few friends, had a lot of fun. If you really want to jump some waves and go wild, get a jetski to yourself - otherwise the person on the back will be pretty uncomfortable. Oh, and definitely bring sunglasses or even goggles, the water will be assaulting your eyes non stop. Pigs on the beach were pretty cool.”

“We visited 3 beaches on the tour and 2 of them had a noticeable amount of trash on them. Disappointing for a National Park, they need to ensure they are cleaning up and implement something to safeguard against people littering. Wouldn't recommend going until they get it cleaned up. We saw about 3 fishes in the snorkelling, experienced much better snorkling at a beach on Koh Tao. Our tour seemed a little bit unorganised as we had to wait quite a while to have a turn in the kayak and didn't think we were going to get the chance to do it. We could have enjoyed the beach we were…”
