Fantastic 5.0
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.

Wonderful experience in Koh Samui! Thank you to the team for the smooth arrangements for my last-minute request. They were very responsive with a reasonable price and the private trip was very flexible. Although we had limited time to go snorkelling and visit Pig Island, we could communicate with the captain to fit our schedule. Highly recommended to go there with Discover Thailand!✨

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.

Very well organized and great spots. Only the light breakfast is a bit sparse.

Prompt pick up at lobby, smooth ride. Clear information, easy to follow instructions. 2hrs on Pigs Island, ample time to take pictures, feed the pigs and chill around. You can even choose to kayak (included) if you want. Free cold drinks provided on speedboat. No hard pressing to purchase anything. Up to 45min snorkeling before returning to Samui for yummy Thai lunch. Overall very satisfied with the tour!

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!

What to know before visiting Ko Samui

What to expect in Ko Samui

The things-to-do catalogue here is led by Tours, Outdoor & sports activities, Water activities, Massages and Cruises, so you can mix guided sightseeing with active outdoor options and plenty of water-based choices. That spread means travellers can easily slot a short massage or water activity between longer tours or multi-hour cruises. Demand peaks in February and eases to its quietest in October, so expect busier services around February and a calmer booking environment in October.

Choosing which activities to book

A key decision is whether you want broad variety or a simple, affordable option — Tours offer a wide range of prices while Water activities sit at the most affordable typical price. Tours show a wide spectrum of options from SGD 42 entry-level up to SGD 134 at the upper end, so shopping around can find very different experiences; by contrast, Outdoor & sports activities are tightly priced around SGD 72, so there is less variation to exploit. Use Water activities as the most affordable way to fill gaps in your itinerary, and pick Tours or Cruises if you want the widest choice of styles and budgets.

When travellers from Singapore book

Most travellers book at short notice, typically around 2 days ahead, while the earliest planners usually book about 6 days out. Plan on booking one to four weeks ahead only if you prefer extra cushion for peak periods — that cushion matters most in February.

Water activities SGD 44 SGD 44 – 59
Massages SGD 48 SGD 40 – 59
