Island Hopping Koh Samui: Top Tours & Guide 2026

Short answer up front. The island-hopping day trips worth booking from Koh Samui fall into four groups: the near-Samui snorkel day (Pig Island / Koh Madsum & Koh Tan, calm water, great for kids), the best-reef day (Koh Tao & Koh Nang Yuan, a long day but the clearest water reachable from Samui), the dramatic-landscape day (Angthong Marine Park, 42 limestone islands), and the party transfer (Koh Phangan for the Full Moon Party). Shared join-in trips with us run from ฿1,200 to ฿1,900 per adult, private longtail charters from ฿5,640 per boat — every price includes free hotel pickup and drop-off anywhere on Koh Samui. Most visitors book the first tour a concierge pushes and end up on a 70-passenger boat with a set menu nobody wanted; this guide tells you exactly which islands are worth the boat ride, which tours we actually run, the real per-person prices, and every worry you probably have between now and getting on the water.

The short version so you can stop researching

• Near-Samui snorkel day (beginner, kids, calm water): Pig Island VIP Longtail at ฿1,650 adult / ฿1,400 child, or Pig Island Speedboat at ฿1,350 adult / ฿1,150 child. Departs the south-coast pier. 4–6 hours.
• Best reef day: Koh Tao & Koh Nang Yuan day trip at ฿1,900 adult / ฿1,650 child. 6 AM pickup, ~18:30 return. Long day, genuinely the best snorkel water accessible from Samui.
• Dramatic landscape (42 islands, limestone karst): Angthong Big Boat at ฿1,200 adult / ฿800 child for budget, or Angthong VIP Speedboat at ฿1,750 adult / ฿1,500 child for a smaller, faster group.
• Private charter (groups 5+): Private Longtail at ฿5,640 per boat (1–5 guests; ฿7,560 for 6–10).
• Partying: Koh Phangan Full Moon Party transfer at ฿1,350 — dates only on the full-moon calendar.

The seven islands around Samui worth knowing about

1. Koh Tan (the beginner reef)

20 minutes by longtail from the departure pier on Samui's south coast. Shallow 1–3m reef, white sand sandbar, calm sheltered water. Safe for absolute beginners and kids from age 4. Marine life: clownfish, butterflyfish, parrotfish, small rays on the sand. This is where every family tour we run stops first.

2. Koh Madsum (Pig Island)

The famous one. A small island off the south coast of Samui with a family of pigs that live on the north beach — descendants of pigs released by fishermen years ago. Kids love it. Adults photograph it. The south side of the island has a better coral reef than Koh Tan, accessible only on private tours.

3. Koh Tao (the reef destination)

1.5–2 hours by speedboat from the departure pier on Samui's north coast. Thailand's diving hub. The reefs around Koh Tao deliver 15–20m visibility on clear days, reef sharks, turtles, and hard/soft coral. If you have one day to spend on the water and you want the best snorkeling accessible from Samui, this is it. Long day, not suitable for kids under 8.

4. Koh Nang Yuan (the Y-shaped sandbar)

Three tiny islands connected by a white sand sandbar. The most photographed spot in the Gulf of Thailand. Included on every Koh Tao day trip. The 15-minute climb to the viewpoint gets you the famous Y-shape photo. Snorkel spots around the islands are beginner-friendly because the water is shallow and sheltered.

5. Angthong Marine Park (42 islands, emerald lagoon)

A national marine park 1 hour by speedboat from Samui. 42 limestone karst islands, a hidden inland saltwater lagoon (Talay Nai) inside a crater, a 500-step viewpoint climb, and kayak channels between cliffs. The snorkeling has been damaged by decades of tour traffic — come here for the landscape, not the reef.

6. Koh Phangan

30 minutes by speedboat from Samui's north-coast pier. Famous for the Full Moon Party at Haad Rin beach, but also home to quieter beaches like Bottle Beach (Haad Khuad) and Secret Beach on the north side. During non-party days Koh Phangan is a nicer beach destination than Samui itself.

7. Five Islands (Koh Si Koh Ha)

Rocky limestone cluster on the west coast of Samui. Deeper snorkel spots (4–8m) with dramatic overhangs. Not beginner-friendly but great for people who have done Koh Tan and want something different. Usually combined with Koh Samui highlights tours.

"How many people will be on the boat?" — the group size question

This is the single biggest worry for island hopping. Most travellers book a cheap tour and discover at the pier that they are on a 70-passenger cattle boat with a fixed itinerary and no flexibility. Our group sizes by boat type:

• Longtail: Maximum 8 passengers. Traditional wooden boat, small-group feel, captain knows everyone by name.
• Speedboat group: Maximum 20 passengers. Faster but still manageable group. Multiple pickup stops.
• Angthong big boat: 50–70 passengers. Cheapest option, fixed itinerary, expect queues at the viewpoint climb.
• Angthong VIP speedboat: 20–30 passengers. Faster, smaller group, better lunch, worth the extra baht if you hate crowds.
• Koh Tao day trip: 20–30 passengers. The speedboats are comfortable.
• Private longtail: Whole boat for your group only, up to 10 passengers. For groups of 5+ this is cheaper per person than the group tour.

"The boat ride is going to destroy me" — the seasickness worry

Longtail boats are stable and slow. Speedboats are fast and bouncy. Nobody gets sick on a longtail doing the 20-minute Koh Tan run. Everyone feels the 2-hour Koh Tao speedboat ride. The mitigation:

• Take a motion sickness tablet 60 minutes before pickup. We keep spares on board at 40 THB each.
• Sit in the middle of the speedboat, not the front. The front bounces hardest.
• Eyes on the horizon, never on your phone.
• Light breakfast (toast, banana) — not coffee and pastries on an empty stomach.
• Stay hydrated with water.

If you know you get violently seasick even with medication, skip the Koh Tao day trip. Book a Koh Tan longtail instead.

"What if the reef is dead?" — honest site-by-site assessment

The reefs near Samui (Koh Tan, Koh Madsum) are moderate — 5–10m visibility, healthy enough coral, plenty of fish for beginners. Not world-class but absolutely worth a half-day. The reefs at Koh Tao are genuinely good — 15–20m visibility on clear days, coral walls, reef sharks, sometimes turtles. The reefs at Angthong have been damaged by decades of tour traffic — 3–5m visibility, mostly dead coral. Come to Angthong for the landscape, not the snorkeling.

"What about hidden fees and park entries?" — what we include

Every tour we quote is all-in:

• Hotel pickup and drop-off anywhere on Koh Samui in an air-conditioned minivan
• Boat, captain, and crew
• Snorkel mask, snorkel, fins (sized for everyone including kids)
• Life jackets in every size
• Bottled water and fresh fruit, unlimited
• Lunch on full-day tours (buffet on Koh Nang Yuan beach or Angthong)
• National park entry fees (300–500 THB per adult — included, not charged at the pier)
• English-speaking captain and guide

Not included: alcohol on board (beer and soft drinks can be bought), tips (optional, 100–200 THB per adult is standard).

"What is the best route if I only have one day?" — honest recommendation

If you have one day and want the best experience: book the Koh Tao & Koh Nang Yuan day trip. The boat ride is long but the reefs on the other side are genuinely good.

If you have half a day and are travelling with kids: book the Pig Island VIP Longtail. Short, sheltered, kid-friendly.

If you have two days: do Pig Island + Koh Tan on day one (relaxed, builds confidence), Koh Tao on day two (the big one).

If you are a landscape photographer: do Angthong Marine Park. The emerald lagoon and limestone cliffs are what you came to Thailand to photograph.

If you are a group of 5 or more: book a private longtail charter at ฿5,640 per boat (1–5 guests) — cheaper per person than group tours and fully flexible.

Weather — exact thresholds, no judgement calls on the day

We cancel tours automatically when the wave forecast exceeds 1.2 metres, wind crosses 25 knots, or there is lightning within 30 km of Koh Samui. The decision is made by 06:00 based on the Thai Meteorological Department forecast. You get notified by chat. Full refund or free reschedule to another day in your trip — your choice, no pressure to go anyway. During monsoon months (late October through early December) cancellations happen more often, so book with flexible dates. December through April is reliable — 1–2 cancellations per month at most.

Who we are — killing the "is this a scam" worry

Tour In Koh Samui is the retail brand of Southeast Asia Co., Ltd., a Thai-registered company operating under TAT Tourism Licence 44/00448 (Company Reg. 0845567018501). We partner directly with the local captain-operators — booking flows through us so the captain keeps the full margin, not a platform, and not a subcontracted marketplace. When you book direct with us the price goes to the crew, not to a Viator or GetYourGuide platform taking 20–25% margin. If you want to verify us before booking, our TAT licence 44/00448 is public on the Thailand tourism registry, and our verified guest reviews are on our reviews page.

How to book

Chat with us at tourinkohsamui.com with (1) your dates, (2) your hotel on Samui, (3) group size and ages, and (4) any specific interests. We reply within 2 hours during the day with 2–3 specific options that fit, a clean price with child or group discounts already applied, and confirmation of availability. No card details needed to check availability. Full refund up to 48 hours before departure.

Seasonality — which months are best

Koh Samui has two distinct seasons. The dry season runs November through April — calm seas, reliable sunshine, minimal rain, and the most dependable tour conditions. This is peak booking time and prices can rise slightly around Christmas, New Year, and Chinese New Year (late January to early February). The shoulder months of March, April, and November tend to offer the sweet spot of good weather with fewer crowds.

The rainy season is mid-October through early December, when the north-east monsoon hits the Gulf of Thailand. Afternoon thunderstorms are common, wave heights increase, and we see more tour cancellations (typically 4–6 days per month). If you are booking during monsoon, have flexible dates and expect at least one weather-based reschedule. May through September is in between — warmer, humid, afternoon rain possible but mornings usually clear. Visibility underwater is best from March through May.

Hotel pickup logistics and timings

Every tour we run includes hotel pickup from anywhere on Koh Samui. We use air-conditioned minivans with seat belts, and the drivers carry extra bottled water for guests. The night before your tour, you receive a chat confirmation with the driver's name, van plate, and exact pickup time.

Pickup times vary based on your hotel location and the departure pier used for the tour. Chaweng and Lamai hotels get picked up earliest because they are furthest from the south-coast pier — morning tours typically start collection around 07:30. Bophut, Maenam, and Choeng Mon are 30–45 minutes closer. Hotels on the south side of the island, Taling Ngam, or Laem Sor are only 10–15 minutes from most piers. Afternoon and sunset tours adjust proportionally — usually 14:30 to 16:00 pickup depending on departure time and pier.

Combining this tour with other activities

Most guests do not book just one tour during a Samui trip. Pairing tours well gives you variety and maximises your time. Our most-requested combinations:

• Morning boat + afternoon temple: A snorkel or sunset tour in the morning, then a half-day cultural safari in the afternoon. Works well because the boat tour ends around midday and the land tour is shorter and easier.
• Morning temple + afternoon boat: Start with a Big Buddha and Wat Plai Laem stop, then head to a half-day longtail. Best for travellers who want cultural depth before the water.
• Full day cultural immersion: Thai cooking class in the morning (09:00–13:00), temple visit in the afternoon, Muay Thai stadium in the evening. The "deep Thailand" day.
• Adventure + relaxation: ATV or zipline tour in the morning, sunset boat tour in the evening. Opposite pace, best of both.
• Family two-day combo: Day 1 — elephant sanctuary half day + afternoon beach. Day 2 — Pig Island longtail. Gentle pacing for kids.

If you send us your dates and group composition, we will suggest 2–4 tour combinations that fit your interests, budget, and pacing preferences. We do not upsell — if your budget says one tour is the right answer, we tell you that.

Why our prices are what they are — and where you can save

Tour prices in Koh Samui vary wildly, often by 50% or more between operators running similar routes. The differences are not random. Cheaper operators typically skip one or more of these: proper children's life jackets in every size, first-aid equipment, licensed insurance, English-speaking captains, a fuel buffer for route flexibility, or the park entry fees (which then get charged at the pier as a "surprise"). Our quoted prices include all of these.

If you want to save money without compromising safety, the best levers are: (1) book direct with us rather than through Viator, GetYourGuide, or Klook — the platforms take 20–25% margin that goes to them, not the operator; (2) book in shoulder season (March–April or November) when demand is lower; (3) look at group discounts for parties of 10+ which can cut the per-person cost; (4) consider a private charter if you are 5 or more people — per-person prices on a private longtail often match or beat group tours.

What guests tell us after — the recurring comments

After nine years of running these tours we have heard the same things over and over. The feedback patterns are useful for setting expectations before you book:

• "It was easier than I thought" — a significant share of first-time travellers arrive expecting the activities to be harder or scarier than they actually are. The longtails are more stable than people expect, the snorkel sites are more forgiving, the kayaks are easier to paddle.
• "The small group size made the difference" — guests who book our small-group options (max 8 passengers on longtails) frequently mention it versus previous trips they did on 50-passenger cattle boats elsewhere in Thailand.
• "We wish we had booked longer" — about a third of guests finish their tour wishing they had booked a full day instead of a half day, or a private charter instead of a group.
• "The honest weather cancellation policy was a relief" — people who have had bad experiences with operators forcing them onto the boat in marginal conditions specifically thank us for the "we cancel for safety" approach.
• "The kids loved it more than we did" — family groups consistently report that kids enjoyed the day more than parents expected.

Common mistakes first-time travellers make — and how to avoid them

• Booking the cheapest tour on arrival from a concierge. Hotel concierges are paid commissions, so they push specific operators — often 50-passenger cattle boats with fixed itineraries. Research ahead and book direct before you arrive.
• Skipping motion sickness medication. Even travellers who say "I don't usually get seasick" can struggle on a 2-hour speedboat ride. Take a tablet 60 minutes before pickup as insurance.
• Bringing too much stuff on the boat. You do not need a beach bag for a 4-hour boat tour. You need sunscreen, hat, water, phone, and cash. Everything else stays in the van.
• Wearing flip-flops on boats. Wet flip-flops are dangerous on fiberglass decks. Bring sandals with straps or proper water shoes.
• Not drinking enough water. Sun, salt, wind, and exercise all dehydrate you faster than you realise. Water is free and unlimited on the boats — use it.
• Booking only one day on the water. Koh Samui is worth at least two boat days. Book a relaxed half-day first to get your sea legs, then a full day trip after.

People also ask — island hopping from Koh Samui

Q: What boat trips can you do from Koh Samui?
A: The main island-hopping day trips from Koh Samui are: Pig Island (Koh Madsum) & Koh Tan for easy snorkeling and beaches (from ฿1,350 adult); Angthong Marine Park for 42 limestone islands and an emerald lagoon (from ฿1,200 adult); Koh Tao & Koh Nang Yuan for the best snorkeling reachable from Samui (฿1,900 adult, a long day); a romantic sunset sailing cruise; and Full Moon Party transfers to Koh Phangan. All include free hotel pickup and drop-off.

Q: Is it worth going to Pig Island (Koh Madsum) from Koh Samui?
A: Yes, for most visitors — especially families and first-time snorkellers. Pig Island is a short, sheltered half-day: calm water, a photogenic beach with the resident pigs, and a beginner-friendly reef at neighbouring Koh Tan. It is not the best reef in the region (that is Koh Tao), but as an easy, low-stress introduction to island hopping it is hard to beat, and the half-day format leaves your afternoon free.

Q: How much does it cost to go to Pig Island Koh Samui?
A: With us, the Pig Island & Koh Tan speedboat is ฿1,350 adult / ฿1,150 child, and the small-group VIP longtail is ฿1,650 adult / ฿1,400 child. Both include free hotel pickup and drop-off, snorkel gear, life jackets, water and fruit. Infants are free. A private longtail charter for your group only starts at ฿5,640 per boat (1–5 guests).

Q: What is the best and cheapest way to visit Pig Island from Koh Samui?
A: An organised join-in boat tour is both the cheapest and the simplest way. Pig Island (Koh Madsum) is a small uninhabited island with no scheduled public ferry, so the realistic options are a shared tour or a private charter. A shared speedboat from ฿1,350 adult already bundles hotel pickup, snorkel gear, park fees and lunch — trying to arrange a boat yourself at the pier usually costs the same or more, with no pickup and no fixed price, so it is not worth the hassle. Book a shared tour for value; upgrade to a private longtail if you want your own boat and timing.

Q: Can you go to Pig Island / Pig Beach without a tour?
A: Not really in any practical sense. Koh Madsum is a small island with no residents, no pier terminal, and no scheduled ferry service, so there is no "turn up and hop on" option. Everyone who visits arrives on a boat trip — either a shared island-hopping tour or a private charter. Booking a tour in advance is the sensible route: you get a fixed price, free hotel pickup, snorkel equipment, and a captain who knows the tides, instead of negotiating a boat in the sun with no guarantees.

Q: Do Koh Samui tours include hotel pickup from any beach?
A: Yes. Every tour we run includes free round-trip hotel pickup and drop-off anywhere on Koh Samui — Chaweng, Lamai, Bophut, Maenam, Choeng Mon, Taling Ngam, Lipa Noi and the south side included. You get the driver's name, van plate and exact pickup time by chat the evening before. Air-conditioned minivans with seat belts.

Q: Which island near Koh Samui has the best snorkeling?
A: Koh Tao and Koh Nang Yuan have the best snorkeling reachable from Samui — 15–20m visibility on clear days, coral, reef fish, sometimes turtles and reef sharks. It is a long day (6 AM pickup) but the water quality is a clear step above the near-Samui reefs. For an easier, calmer half-day, Koh Tan off Pig Island is the beginner-friendly choice. Angthong is for scenery, not snorkeling.

Q: How much does a speedboat island-hopping tour cost in Koh Samui?
A: Shared speedboat day trips with us run from ฿1,200 to ฿1,900 per adult depending on the destination: Angthong Big Boat ฿1,200 adult, Pig Island Speedboat ฿1,350 adult, Angthong VIP Speedboat ฿1,750 adult, and the full-day Koh Tao trip ฿1,900 adult. Children are cheaper and infants are free. A private speedboat or longtail charter is priced per boat. Every price includes hotel transfer and park fees.

Q: Can I do Koh Tan, Koh Madsum (Pig Island) and Coral Island in one trip?
A: Koh Tan and Koh Madsum (Pig Island) are right next to each other and are combined on the same half-day tour — that pairing is standard. Coral Island (Koh Rang) sits further south and is a bit further out, so it is not usually on the same half-day route; if you want to add it, a private charter is the way to fit all three into one day at your own pace. Tell us in chat and we will map a route that works.

Q: Is half a day enough for Pig Island from Koh Samui?
A: Yes. The standard Pig Island & Koh Tan trip is a 4–6 hour half-day, which is plenty of time for the beach, the pigs, and a couple of snorkel stops without feeling rushed. It leaves the rest of your day free for a temple visit, a cooking class, or the beach. Only book a full day if you specifically want to add more islands or a private charter.

Q: How do I get to the Full Moon Party on Koh Phangan from Koh Samui?
A: The easiest way is a round-trip Full Moon Party transfer with hotel pickup and drop-off from ฿1,350 — a speedboat across to Koh Phangan in the evening and a guaranteed boat back after the party, so you are never stranded at Haad Rin at 3 AM. Parties run to the full-moon calendar, so dates are fixed each month; book ahead because transfers sell out on party nights.

Q: How many days do you need in Koh Samui for island hopping?
A: Two to three days on the island is enough to fit in the island hopping worth doing without rushing. A good rhythm is a relaxed near-Samui half-day (Pig Island / Koh Tan) to get your sea legs, then a full reef day to Koh Tao & Koh Nang Yuan, with a scenery day at Angthong if you have a third. Space boat days apart with a land day (temples, elephants, cooking class) so you are not on the water back to back.
