REVIEW · SURAT THANI PROVINCE
Koh Samui: Koh Madsum and Koh Tan Long Tail Boat Trip
Book on GetYourGuide →Operated by Grand Sea Discovery · Bookable on GetYourGuide
Koh Samui gets a whole lot calmer on this island hop. You’ll get hotel pickup, a private boat ride, and two standout stops: beach time at Koh Madsum and snorkeling at Koh Tan in clear, warm water. I love how it feels like a mini reset—less planning, more time in the sun and sea.
The trip also has real people-care built in. Guides such as Arthur and Albert have been praised for being attentive, quick to help if you get scratched by coral, and even for snapping good photos while you relax by the shoreline. My only caution is timing: this is a short 5-hour format, and you’ll want to be ready for a bit of a fast pace between islands.

Key things to know before you go

- Private group of up to 3 people means quieter time on the boat and more flexibility with your pace
- Koh Madsum beach time includes swimming, relaxing, and options like kayaking
- Koh Tan snorkeling comes with mask and life jacket, with lots of small fish and even ray sightings
- You can get wet on the boat ride, so plan for a dry bag and a change of clothes
- Koh Madsum admission fee (THB 50 per person) is not included, so budget a little extra
From Bo Put, Maenam, or Maret to Thong Krut Pier: the start matters

This tour is built around convenience. Your guide picks you up from Bo Put, Maenam, or Maret, then you ride to Thong Krut Pier to connect with your private boat. If you hate “meet here at 9” logistics, this part is the easy win.
Once you reach the pier, it’s a short water transfer over to Koh Madsum—about 15 minutes from Koh Samui by boat. That quick hop is nice because it keeps you from wasting the morning in transit, but it also means conditions can feel breezy and splashy, especially on a longtail-style ride.
Koh Madsum beach time: where the sand-and-sea plan pays off

Koh Madsum is the first big highlight, and it’s a classic “arrive, drop your bag, and do nothing” island. When you step off the boat, you get free time on the beach—time to swim, relax, and explore the island at your own pace. If you like your vacations to include at least one slow, salty block of hours, this stop delivers.
It also comes with a small catch you should plan for: Koh Madsum admission is THB 50 per person and is not included. Bring some cash just in case, and don’t wait until the last minute to sort it out.
You might hear the vibe described as Pig Island (people do talk about the resident pigs when they’re there). Either way, the real reason you’re going is the water-and-sand combo. One guide helped guests take care of bags while people chilled at the beach, which is a smart detail: you can focus on relaxing instead of constantly managing your stuff.
What to do during your Koh Madsum time
You’ll have options, including:
- Swimming and wading (the whole point)
- Relaxing on the beach without a strict agenda
- Kayak time if you want to move around a bit
And here’s my practical advice: treat the beach time as your “reset window.” If you’re going to snorkel later, start lighter here. Sunscreen, a hat, and a towel are your friends, and a packed lunch can save you if you get hungry between stops.
Koh Tan snorkeling: crystal water, simple gear, real marine life

After Koh Madsum, you head onward to Koh Tan for snorkeling. This is where the trip earns its bragging rights. The water is described as clear, and you’re guided into what’s under the surface—so you’re not just paddling around looking for a “maybe fish” moment.
Snorkeling equipment is included: you get a snorkeling mask and a life jacket, plus a guide. That matters because Thailand’s coastal water can be calm one minute and choppy enough to be annoying the next, and having the right gear makes it easier to enjoy the sea life instead of wrestling with equipment.
What you might see
The most common “what you’ll get” is fish and marine life in the clear water. A really specific detail to note: some experiences include two ray sightings during the snorkeling portion. Even if you don’t see rays every time, it’s a strong sign that Koh Tan can have surprising life.
How to make snorkeling more comfortable
If you’re not a daily snorkeler, keep it simple:
- Rinse your mask quickly if it fogs up
- Go slow when you enter the water
- Keep your breathing steady so you can actually watch what’s around you
Also, coral is beautiful—but it’s also where scrapes can happen. One guide was praised for noticing a cut by coral and helping right away. That’s exactly the kind of calm, competent attention you want in the water.
The boat ride reality check: getting wet is part of the deal

This tour is a “boat day,” even if you’re only on the water for short stretches. One of the more practical lessons here is that you can get quite wet on the journey—enough that a dry change of clothes and a waterproof bag can be a lifesaver. Pack smarter than you think you need to.
I’d also plan for basic comfort:
- Bring sunglasses (you’ll want them)
- Wear swimwear you don’t mind rinsing later
- Use sunscreen before you’re out in the sun
- Keep a towel accessible
One more small point: this is a short day. If you’re sensitive to rushed transitions, you might want to check how your guide plans timing between Koh Madsum and Koh Tan before you commit. A couple of experiences have felt tight on time, so your best defense is asking for a clear expectation.
Guide attention and small moments that change the day
In a good island tour, the guide does more than point at scenery. Here, the guide role shows up in three helpful ways.
First, the guide is often praised for being attentive and quick to help if someone gets nicked or scraped. That coral-awareness matters. Second, there’s photo support: one guide was noted for taking great photos without making the group feel awkward or rushed. Third, guides can help with practical stuff like handling bags while you’re relaxing at the beach, which keeps you from doing your “bag-juggling tango” every five minutes.
You may meet different guides depending on your day. Names mentioned include Arthur and Albert, and both have been described as friendly, supportive, and focused on making the experience work for the people on board.
Price and value: is $188 per group up to 3 a fair deal?

Let’s talk money in a way that helps you decide. At $188 per group (up to 3 people), you’re not paying for a big mass-market cruise. You’re paying for a private setup that includes:
- Hotel pickup and drop-off
- A private boat trip
- Water and soft drinks on board
- Snorkeling mask and life jacket
- An English-speaking guide
You’re also paying for the time efficiency: the Koh Samui to Koh Madsum transfer is quick, and the day is structured around two water-focused stops.
So where can value feel shaky? Two reasons:
- Time limits: it’s a 5-hour tour, so you’re not settling in for an all-day island hangout.
- Food isn’t included: if you’re used to tours where meals are part of the package, you’ll need to plan your own lunch/snacks.
If you’re traveling with 1–3 people and you want privacy plus snorkeling gear plus pickup, it can feel fair. If you’re mostly after a simple boat crossing with minimal time in the water, you may feel the price is high for what you get.
My suggestion: decide based on your style. If you’re the kind of traveler who values a calm, guided schedule with the right gear, it’s a good fit. If you want a slow, long island day, you might prefer a longer day trip.
What’s included vs what you’ll pay on your own

Here’s the practical checklist.
Included:
- Pickup and drop-off
- Private boat trip
- Water and soft drinks
- Snorkeling mask and life jacket
- Guide
Not included:
- Koh Madsum admission fee: THB 50 per person
- Food and drinks at the islands
Because food isn’t included, bring a plan. The tour’s guidance includes packing a lunch and bringing food/drinks. Even if you don’t eat everything, you’ll feel better having options when the day gets sunny and you’re burning energy in the water.
Who should book this, and who should skip it
This trip is best for people who want two water moments in one day: beach time first, snorkeling second, with pickup to reduce hassle.
It’s a great match if:
- You’re traveling in a small private group
- You want snorkeling gear handled for you
- You like relaxed beach time, not a strict museum-style itinerary
- You appreciate a guide who helps keep things smooth and safe
It’s not suitable for:
- Pregnant women
- People with back problems
- Wheelchair users
Also, be honest about weather and motion tolerance. Short as the ride is, it’s still a boat day, and you can get wet quickly.
Should you book this Koh Madsum and Koh Tan boat trip?
If you’re craving clear water and white-sand downtime without spending hours organizing transport, I think this is a solid booking. The biggest strengths are the private group, the guided snorkeling setup, and the way Koh Madsum gives you a real chance to slow down.
Still, I’d book with eyes open. This is a 5-hour experience, so it’s not for people who want long, lazy island marathons. Bring a dry bag, consider packing a change of clothes, and plan for the THB 50 Koh Madsum fee so the day stays stress-free.
