The hotel pickup was on time and the car was clean. Breakfast on board consisted of bananas, muffins, and drinks. You need to fill out the passenger manifest. The guide tries hard to explain the precautions in English. They talk for a long time, but to summarize: when heading to the island, you will transfer to a smaller boat (a long-tail boat) and get off at the island's floating pier. Your feet won't get wet. The paths on the island consist of extremely steep, ladder-like stairs, so please pay attention to your footwear. Since it is a national park, do not swim outside of designated areas. When snorkeling, please borrow a mask from the staff on the island. Don't lose it. Those who want to kayack can transfer to a kayak from the back of the boat. For that, we will lend you a waterproof bag, so put your valuables in it and take it with you. Also, the boat has free water, cola, and sprite in a cooler box, so please help yourself with a cup. Please throw trash in the trash can. We also sell beer, snacks, instant noodles, and smartphone waterproof cases, so please check them out. The boat travels slowly at around 10 knots. Just take it easy. Along the way, your cell phone signal might drop to 3G. Lunch is served after returning from the first island by small boat, where food is plated one by one in order, cafeteria-style. It is not a buffet. It might be difficult for picky eaters. Please wear a life jacket for kayaking, taking small boats, and snorkeling. On the way back, a tip box will somehow appear. It's a tour you can enjoy even if you don't understand English. However, you can't expect much from the snorkeling. There are no fish and no coral reefs. You would be better off joining a tour to places like Koh Tao where that is the main focus. The underwater area is full of rocks, so even if you wear water shoes, it will hurt. There are showers on the island. You can also change clothes there.

We had a wonderful day! It started with breakfast after the transfer, consisting of toast and fried dough, jam, peanut butter, as well as Nescafé, water, and juice. There's medication available for seasickness. Afterward, we took a speedboat for about an hour to go snorkeling. Unfortunately, the corals are damaged due to tourism. However, you can still see some fish. We then continued to the main island. Here, you could hike to the viewpoint and go kayaking. Kayaking is unguided, and for the hike, you shouldn't expect an easy path. According to the guide, the ascent and descent take 45 minutes to 1 hour, depending on your fitness level. I personally only went to the first of five viewpoints; even the viewpoint to Emerald Lake is not an easy walk. It involves more ladders than stairs. We were lucky with our guide, Maÿya; she kept everyone in good spirits all day and kept an eye on everyone. Thank you!

we went on the 8am-12pm slot, it was great. not many tourists if visit pig island early, at the same time September isn’t a peak season but there might be transient showers and the sea can be more wavy in the afternoon. Snorkeling time was abit short but we managed to see some cute fishes.

our guides, mikey, Dennis, mr arm & captain jack sparrow were incredible, especially mikey, he was so happy, funny and nothing was to much for him, he also played music. The boat trip itself was very bumpy but me & my family enjoyed that. We didnt see much while snorkeling at koh tao which was slightly disappointing but cant be helped. koh nangyuan was the most beautiful place we have ever seen, my teenagers walked to the viewpoint which they loved. & the water there where you can snorkel was absolutely insane, so clear & warm. We were given toast & hot/cold drinks before we left, then had lunch on a beach at koh tao which was lovely. There was also water/diet coke & Pepsi on board the boat which you could help yourself too. Would recommend this trip.

Great tour, helps you check off the different landmarks around the island of Koh Samui in just a day! The aircon van is also perfect for a hot and sunny day in Koh Samui to chill while going to the next location! One thing i wished could be improved is more introduction to the history of Koh Samui, I felt that there was very little explaination and wished there was more information about the different places and their rich history. Other than that, a very good tour! Would highly recommend!

OMG! Out of the world experience. The staff there is so jolly and fun and supportive. They also take your video. There is a tree house which have the most spectacular view of the Jungle and the Ocean. We spent all our afternoon there. Must go!
