Pig Island(Koh Mudsum) and Koh Tan Half Day Snorkeling Tour
Pig Island is the star of this half-day outing, but the real appeal is the easy pairing of friendly pigs on Koh Mudsum with a short snorkel stop at Koh Tan. You get a speedboat ride, beach time, snorkeling gear, a Thai meal, and hotel transfers in one tidy package.
I like the simple timing and all-in-one price, especially if you have only a few days on Koh Samui. I also like the choice of morning lunch or afternoon dinner, which lets you fit the trip around your plans. The weak point is snorkeling quality can vary, and one recent participant found the site disappointing, so do not book this mainly as a serious snorkeling trip.
Key points to know before booking

- Koh Mudsum is the main attraction: Meet friendly pigs, relax on the beach, and take photos in the shallow water.
- Koh Tan gets about one hour: Bring modest expectations, since the snorkeling stop has received mixed feedback.
- Two useful departure choices: Leave at 08:00 for lunch or 13:00 for dinner, with the afternoon outing ending around 19:30.
- The price covers the basics: At $64 per person, you get a speedboat, guides, transfers, meal, insurance, mask, and life jacket.
- Hotel pickup is shared: Your driver may arrive early or late, and the operator confirms the pickup time in advance.
- This is not for everyone: The operator excludes pregnant women, wheelchair users, babies under one, and people with certain medical conditions.
Why this four-hour island trip works

I see this as a compact sampler of Koh Samui’s nearby islands rather than a full marine excursion. You get two different moods in one outing: the playful, photo-friendly stop at Koh Mudsum and the quieter water time around Koh Tan.
The short format matters. A full-day boat trip can consume an entire holiday day, while this outing leaves room for other plans. At the same time, four hours means each stop is brief. You are not getting a long, unhurried beach stay or an extended snorkeling session.
At $64 per person, the value comes from the bundle. Round-trip hotel transport, the speedboat, an English-speaking guide, snorkeling equipment, life jacket, insurance, and a Thai lunch or dinner are included. You still need money for personal expenses, and the price does not turn the tour into a private charter. It is shared transport and a shared boat experience.
The operator is Northern All Star Co., Ltd. The tour provides English-language guiding, with both a live guide and an English audio guide listed. No individual guide names are provided, so do not book this expecting a particular guide.

The speedboat ride from Koh Samui

Your day begins with pickup around Koh Samui. Enter your hotel name and address when booking, then wait in the lobby five minutes before the confirmed time. The pickup is shared, so the vehicle may arrive early or late. I would avoid scheduling a tight connection immediately after the tour, particularly for the afternoon return.
The listed boat journey takes about one hour. That is a useful part of the experience, not just a transfer. You get open-water views and a fast ride toward the islands, though the motion can be lively. If you are prone to seasickness, bring whatever personal remedy you normally use and stay aware that the tour is not designed for people with serious medical conditions.
The speedboat itself has been one of the strongest parts of the experience for some participants, along with the friendly crew and tour leadership. That praise is worth noting because the boat ride gives the trip energy before you even reach the islands.
The boat portion also sets the practical tone: this is an active outing, not a slow cruise. Protect your phone, carry cash as advised, and bring a change of clothes. You will have water, sand, and spray to deal with.
One hour with the pigs on Koh Mudsum

Koh Mudsum, commonly called Pig Island, is where the tour gets its unusual hook. You can walk along the sandy shore, meet the pigs, and take photos as they move around the beach and shallow water. The pigs are described as friendly and comfortable around people, making this a playful stop rather than a wildlife-watching trip from a distance.
The island is best approached with realistic expectations. Its appeal is the combination of beach scenery and animal interaction, not a long list of sights. You will have about one hour, so the visit gives you enough time to enjoy the shore and take pictures, but not enough time for a slow island day.
A recent participant found Pig Island crowded and less impressive than expected. That is a fair warning. The experience can feel special when the pigs are active and you get a clear moment for a photo, but busy timing can make the beach feel less peaceful. The afternoon outing, which starts at 13:00, may also put you on the island during a hotter part of the day.
Bring sun protection and water-friendly clothing. The tour advises a change of clothes, and that is sensible if you plan to enter the shallows or get close to the swimming pigs. Treat the animals calmly, keep your belongings secure, and follow the guide’s instructions.
Kayaking may also be available at no extra charge, according to one recent account, but it is not listed among the formal inclusions. Consider it a possible bonus, not a guaranteed part of the package. If kayaking is important to you, confirm it with the operator before booking.
One hour of snorkeling at Koh Tan
Koh Tan provides the tour’s quieter nature stop. After the lively Pig Island visit, you get roughly one hour for snorkeling in clear water and time around the island’s unspoiled surroundings. The operator supplies a snorkeling mask and life jacket, so you do not need to bring those items unless you prefer your own equipment.
The setting sounds appealing, but this is where you should keep your expectations in check. One participant called the snorkeling excellent, while another found the snorkeling spot very disappointing. That difference may reflect sea conditions, visibility, expectations, or the exact spot used on the day.
I would book this as a pleasant chance to look beneath the surface, not as a dedicated marine-life expedition. If snorkeling is the main reason you are visiting Koh Samui, you may want a tour built around longer water time and a stronger focus on reef conditions. If you simply want an hour in the sea as part of a wider island outing, Koh Tan fits the bill.
The water may look clear, but clear water does not guarantee a spectacular underwater scene every day. Weather and conditions can change the experience. The included life jacket is useful for comfort and safety, especially if you are not a confident swimmer.
After snorkeling, you return to Koh Samui by speedboat. The scheduled experience finishes with hotel or personal-address drop-off, which makes the package convenient for visitors who do not want to arrange their own taxi.

Morning lunch or afternoon dinner
The schedule is one of the tour’s better features. The morning trip leaves at 08:00 and provides lunch. The afternoon trip leaves at 13:00 and provides dinner, with the end time around 19:30 and some return options listed around 20:00.
Choose the morning outing if you want cooler conditions and a daytime meal. It also gives you the rest of the afternoon back on Koh Samui, with the listed return around 15:00. This is the better choice if you have dinner plans or want to avoid arriving back late.
Choose the afternoon outing if you prefer a slower start or want to pair the trip with dinner. The tradeoff is heat and timing. One participant specifically advised caution about hot days and peak times, and that is useful advice for Pig Island, where the beach can feel less relaxing when crowded and exposed to the sun.
The meal is Thai food, with lunch for the morning session and dinner for the afternoon session. The supplied details do not specify the menu, so do not choose this tour based on a particular dish or dietary promise. If you have food restrictions, ask the operator before paying.
One helpful detail comes from a participant who had to leave early for a ferry. The staff prepared a packed lunch, which suggests the crew can be considerate when plans change. That was a special situation, not a published guarantee, so you should still plan around the normal schedule.
What the $64 price really includes

The $64 price is reasonable if you need transport and equipment. Paying separately for a hotel transfer, boat ride, guide, snorkeling mask, life jacket, meal, and insurance could become more expensive and less convenient. You also avoid the trouble of arranging a boat to two islands yourself.
The value is less convincing if you already have transport, your own boat plans, or little interest in snorkeling. Pig Island is a short visit, and Koh Tan receives about one hour. You are paying for convenience and variety more than for long time at either island.
This is also a shared tour. You should expect other people in the vehicle and on the boat. Shared trips keep the cost down, but they reduce control over departure and return timing. The pickup can be early or late, and the operator confirms the actual time in advance.
Free cancellation up to 24 hours before departure and reserve-now-pay-later booking add useful flexibility. Those policies matter in Koh Samui, where rain and sea conditions can affect outdoor plans. Check the exact terms at booking, especially if your schedule may change.
Who should book this outing

I think this tour suits first-time visitors who want a short taste of Koh Samui’s nearby islands without giving up an entire day. Families with children aged four and older may like the pigs and beach time, provided everyone meets the health and safety requirements.
It also fits couples and small groups who want a light adventure with a meal included. The speedboat gives the day some excitement, while the island stops keep the plan simple.
I would be more cautious if you are a committed snorkeler. The mixed impressions of Koh Tan mean the water stop may not meet high expectations. You should also think twice if you dislike shared transfers, crowds, heat, or a fixed schedule.
The activity is not recommended for pregnant women, wheelchair users, babies under one, people with high blood pressure, epilepsy, heart disease, or other serious medical conditions. The information also excludes people over 70 and separately lists people over 95, so the age guidance is unusually restrictive. Ask the operator if you are unsure about eligibility.
Practical packing advice for Koh Mudsum and Koh Tan

Keep your packing light. A change of clothes is specifically recommended, and it will be useful after the boat ride, beach stop, and snorkeling. Bring cash for personal expenses, plus sun protection and any medication you normally need for boat travel.
A phone or camera is worthwhile for Koh Mudsum, but protect it from water and sand. You will want both hands free at times, especially near the pigs and while getting on or off the boat.
Wear clothing that works for swimming and beach time. The tour supplies a mask and life jacket, but you may bring personal snorkeling equipment if you prefer. The operator does not list towels or other personal beach items among the inclusions, so pack accordingly.
Arrive at the departure location 10 minutes before the selected departure time, even though hotel pickup instructions ask you to wait five minutes before the scheduled pickup. The key point is to be ready early. Do not assume the 08:00 and 13:00 options are interchangeable after booking.
Should you book the Pig Island and Koh Tan tour?

Book it if you want a convenient half-day outing with a fun animal encounter, a speedboat ride, a short snorkeling stop, and a meal wrapped into one price. The pigs give Koh Mudsum a memorable twist, and the friendly crew and lively boat ride can make the day feel easy and enjoyable.
Skip it if your priority is outstanding snorkeling, quiet beaches, or a private island experience. Koh Mudsum can be busy, and Koh Tan may not deliver the underwater quality you hope for.
For most visitors, I would choose the 08:00 departure. You avoid some afternoon heat, receive lunch, and return around 15:00 with the evening free. Choose 13:00 only if dinner on the water appeals to you or your morning is already full. At $64, it is a solid convenience-focused trip, as long as you see Pig Island as the main event and Koh Tan as a pleasant extra rather than the reason to book.
