Koh Samui: Koh Tan and Koh Madsum Half-Day Tour by Catamaran

The star of this half-day outing is Koh Madsum’s friendly swimming pigs, but the boat time is just as important. You’ll ride a roomy power catamaran from Koh Samui, stop at Koh Tan for snorkeling and water activities, then spend time on the beach with the pigs. I like the generous mix of swimming, paddleboarding, kayaking, and the onboard slide. I also like that the price includes transfers, food, drinks, equipment, and insurance.

The main catch is that the snorkeling can be hit or miss. One stop may offer clear water and colorful fish, while another may produce little to see. You should also expect a busy schedule, some waiting before boarding, and a fairly energetic boat day that is not suited to people with certain medical conditions, back or heart problems, pregnancy, or limited mobility.

Key points at a glance

• Pig Island gives you real time with friendly pigs: You can feed, pet, and photograph them in the shallow water, then relax on the beach.
• The catamaran has more comfort than a basic speedboat: Seating includes chairs, sofas, bean bags, and sunbeds, with an air-conditioned room and toilets onboard.
• Koh Tan is the active stop: Expect snorkeling, swimming, paddleboarding, kayaking, and a large inflatable slide.
• The $70 price covers plenty: Hotel transfer, a cooked meal, fruit, water, soft drinks, equipment, crew, guide, and insurance are included.
• Snorkeling depends on conditions: The sea may be clear, but fish sightings are not guaranteed.
• This is a lively boat outing, not a quiet island escape: The schedule suits families and active adults more than people seeking solitude.

From Koh Samui hotel pickup to the pier

Your day begins with a shared transfer from Koh Samui to the Ocean King Samui pier. Pickup areas include Mae Nam, Bophut, Bangrak, and Choeng Mon, followed by Nathon, Chaweng, Chaweng Noi, Lamai, and Hua Thanon.

The stated pickup windows vary by trip and location. Morning departures are generally collected between 7:45 and 8:30 a.m., while afternoon pickups begin around noon and can extend into the early afternoon. The more specific afternoon schedule lists Mae Nam, Bophut, Bangrak, and Choeng Mon at about 12:00 to 12:15 p.m.; Nathon, Chaweng, and Chaweng Noi at 12:15 to 12:30 p.m.; and Lamai and Hua Thanon at 12:45 to 1:00 p.m. Confirm the exact time in your email before setting out.

The transfer is a useful part of the deal. You do not need to arrange your own taxi to the pier, and recent departures have used comfortable minibuses with reclining seats. Allow some patience at the pier, though. You may arrive before boarding while the operator gathers people from around the island. Bring water and sun protection for this waiting period, since refreshments may not be served until you are onboard.

A power catamaran with room to spread out

The boat is one of the stronger points of the outing. It is described as a speedy power catamaran, so the crossing feels quicker than a slow sightseeing cruise. At the same time, it has several seating areas instead of one cramped deck.

You can find chairs, sofas, bean bags, and sunbeds, with places at the front, middle, and upper level. An air-conditioned room offers a break from the heat, and onboard toilets are available. These details matter on a four-hour trip, especially if you are traveling with children or prefer not to sit in direct sun for the whole ride.

The catamaran also carries life jackets and snorkeling equipment. The professional team includes the captain, crew, and an English and Thai speaking guide. The guide provides information about the islands and their sea life, while the crew handles the practical work of moving people between activities.

The boat is set up for fun rather than quiet luxury. The inflatable slide is a major attraction and is put out during the water stop. You can also swim beside the boat, use a paddleboard, or take a kayak. Kayaking may cost an additional 300 baht, so carry cash if you want that option.

Koh Tan: snorkeling, swimming, and the inflatable slide

Koh Tan, also called Coral Island, is the first main activity area. The scheduled stop lasts about an hour, although the exact timing and order of activities can change with sea and weather conditions.

You can snorkel with the provided mask and other equipment, look for coral formations and tropical fish, and spend time in the water. The island is promoted for its marine life, but keep your expectations sensible. Snorkeling visibility varies, and one stop may have very few fish. This is best treated as a chance to get in the water rather than a guaranteed wildlife encounter.

The water stop is more than snorkeling. The crew sets up an inflatable slide from the catamaran, and this becomes a favorite activity for children and adults who enjoy a splash. Paddleboarding is available, and kayaking gives you another way to explore the calm water, though the kayak charge is separate.

If you prefer not to use the slide, you can sit on the boat, swim at your own pace, or watch the action from the deck. I like this flexibility because the tour does not force everyone into one activity. Still, the stop is active and social. If your ideal boat trip means silence, a small group, and long stretches of empty sea, this will feel too busy.

Food is served onboard around this part of the outing or later in the schedule. The meal has included fried chicken, fried rice, noodles, Thai dishes, and fruit. Vegetarian choices have been available, but the range may be limited, so tell the operator about dietary needs when booking rather than assuming a broad vegetarian menu.

Koh Madsum and its famous pigs

Koh Madsum is commonly called Pig Island, and it is the most distinctive stop. After arriving, you can walk onto the beach and see pigs wandering and swimming in the shallows. They are accustomed to visitors and may come close for food and photographs.

The pig encounter is simple, slightly silly, and memorable. You can feed and pet the animals, take pictures in the shallow water, or step back and watch. The pigs are the reason many people choose this trip, so the island can feel crowded around the animals and landing area.

You also get time away from the pigs. The beach is suitable for a short walk, sunbathing, and swimming, with scenic views along the shore. The scheduled break is about an hour, though some departures have allowed around an hour and a half. That is enough time to enjoy the pigs without rushing every photograph, but not enough for a long, unhurried island afternoon.

Bring sandals or beach shoes, swimwear, sunscreen, and a camera. Cash is also sensible for personal purchases and any food or activity charges. Keep your belongings secure near the water, and follow the crew’s instructions around the pigs. The animals may be friendly, but they are still animals, not props.

What the $70 price really includes

At $70 per person, this is a strong value if you plan to use the full package. You are paying for round-trip hotel transfer, catamaran transport, crew, an English-speaking guide, snorkeling equipment, life jacket, slide access, a cooked meal, seasonal fruit, drinking water, soft drinks, and accident insurance.

The meal adds meaningful value. You are not simply buying a boat ride and then paying for lunch on the island. Food is served onboard, and the portions have been substantial enough to fill people up. Fresh fruit and bottled water are also available, which saves you from buying drinks at each stop.

The price is less attractive if you want a private or peaceful trip. This is a shared excursion with a range of ages and interests. You are paying for a convenient bundle of transport and activities, not for a small boat with a personal guide.

The national park fee is not included, and personal expenses are extra. Kayaking may also cost 300 baht. Carry Thai baht for these additions, even though the main tour is prepaid.

Timing, comfort, and practical drawbacks

The advertised duration is four hours, which makes this easy to fit into a Koh Samui itinerary. You still need to allow extra time for hotel pickup, the drive to the pier, boarding, and the return transfer. The actual time at the islands can shift with traffic, sea conditions, and weather.

A morning trip gives you an earlier start and may leave more of the day free afterward. An afternoon departure offers a later beginning and can work well if you prefer not to rush breakfast. Check the available starting time for your date because the schedule is not identical for every departure.

The tour is not suitable for pregnant women, people with back or heart problems, people with pre-existing medical conditions, or anyone over 60 according to the supplied restrictions. The insurance information also excludes children aged 0 to 3, people with breathing difficulties, and people aged 75 or over. The operator may decline a pregnant passenger’s reservation.

Those rules are worth taking seriously. A fast catamaran, boat ladders, swimming, and an inflatable slide place more demand on your body than a beach day. If you are unsure about your fitness or a medical condition, ask the operator before paying.

The schedule may change because of weather, sea conditions, and traffic. That is normal for a boat trip in the Gulf of Thailand. A rough day can reduce snorkeling quality, alter the route, or shorten time in the water. Free cancellation is available up to 24 hours before departure, and you can reserve now and pay later, which helps if your island plans are still shifting.

Who will enjoy this tour most

I would recommend this outing to families, couples, and active adults who want several activities in one compact trip. Children tend to have plenty to do between the slide, swimming, paddleboarding, pigs, and snacks. Parents also benefit from the boat’s seating, air-conditioned room, toilets, meal, and hotel transfer.

It suits you if you want photographs and easy entertainment more than serious marine study. The pigs provide the unusual photo opportunity, while the catamaran itself offers good spaces for group pictures and sea views.

You should think twice if snorkeling is your main reason for booking. The water may be excellent, but marine life is not assured. Likewise, people seeking a remote beach with few other visitors may find Pig Island too social.

Vegetarians should ask about the menu in advance. The main meal has included several Thai and Western-style dishes, but vegetarian variety has not always been broad. Anyone with allergies should also raise the issue before departure, since no detailed allergy policy is provided.

What to bring for an easier day

Pack light, but bring the essentials:

• Swimwear and a change of comfortable clothes
• Sandals or other secure beach footwear
• Sunglasses and sunscreen
• A camera or waterproof phone protection
• Cash for personal expenses, the national park fee, and possible kayaking
• Any required medication and your booking confirmation

A dry bag would be useful for phones and valuables, although it is not listed as an included item. Use reef-safe habits in the water, avoid touching coral, and listen carefully to the crew before entering the sea.

Should you book Koh Tan and Koh Madsum?

Book this trip if you want a good-value half-day packed with activities and like the idea of combining a comfortable catamaran with Pig Island. The included meal, fruit, drinks, equipment, and hotel transfer make the $70 price easy to justify, especially for families.

Skip it if you want a quiet island day, guaranteed snorkeling, or a private experience. The boat may be busy, the snorkeling can be ordinary, and the waiting and transfers add time around the four-hour cruise.

For most visitors who want an easy, cheerful outing from Koh Samui, this is a sensible choice. Go for the pigs, stay for the slide and water sports, and treat the snorkeling as a bonus rather than the whole point.
