There are a lot of Koh Samui tours for sale, and on booking sites they tend to look the same: a smiling photo, a price, “hotel pickup included”. On the day they can be very different. One trip has a toilet, lunch and insurance; another has a cooler of water and an extra fee at the jetty. This guide sorts the main tour types on the island by price, what is usually included and who each one suits, then shows how to check the operator before you pay.
We are a TAT-licensed tour operator based on Samui (licence 44/00252) and we run three of the trips mentioned below. We have tried to be fair to the ones we do not run, because a good choice matters more to us than a quick sale.
Quick answer: For a first visit, most people book one boat day to the nearby islands and one land day (a 4×4 safari or an elephant sanctuary visit). Expect roughly ฿1,300–3,500 per adult for most shared day tours. Before paying, check the operator’s tour licence, what is excluded from the price, the cancellation and weather policy, and whether accident insurance is included.

The main types of Koh Samui tours compared
Prices below are what we saw listed by Samui operators and the big booking sites in early October 2026, rounded. They change with the season and the agent, so treat them as a guide to what is normal, not as quotes.

Boat and island tours
A day on the water is the trip most visitors remember, and it is where the gap between cheap and good is widest. There are three main kinds.
Speedboat and half-day trips to Koh Tan and Pig Island
These leave from the south and south-west coast, usually Thong Krut or Bang Kao, and pair snorkelling at Koh Tan with the beach pigs on Koh Madsum. Listings run from about ฿1,300 to ฿2,200 per adult for four to six hours. They suit people with half a day to spare. The trade-off is comfort: small boats feel every wave, shade is limited and many have no toilet. Check whether the Pig Island landing fee is included; one listing we checked charges ฿50 per adult on top.
Full-day catamaran trips
A bigger, steadier boat spends the whole day around the southern islands, with lunch and drinks on board. Ours visits the Five Islands, Koh Tan and Pig Island, and the price includes the landing fee, snorkel gear, water toys, a Thai massage, accident insurance and hotel transfers. Our catamaran price guide lines up half-day and full-day prices item by item if you want to compare.
Ang Thong Marine Park (when it is open)
Mu Ko Ang Thong is a national park of 42 limestone islands west of Samui, with the Emerald Lake viewpoint and kayaking under the cliffs. Big-boat tours are the cheapest way in, at roughly ฿1,000–2,000 per adult; speedboats are faster and cost more. The park fee (฿300 per foreign adult, ฿150 per child) is often paid on top. It is a long day with steep steps, and the park is closed from 1 November to 15 December 2026. Our Ang Thong or Pig Island guide compares the two days in detail, and this guide covers what to do during the closure.
4×4 island safari
A driver takes you up into the hills in an open-backed 4×4, with stops at temples, a waterfall, viewpoints and usually lunch. Shared tours are listed at roughly ฿1,400–2,100 per adult; a private 4×4 for the day can run to ฿9,000 or more per vehicle. This is the easiest way to see the inside of the island without driving steep roads yourself, and it keeps going when the sea is too rough for boats.
What to compare: how many people share each truck, whether lunch and entrance fees are included, and how long you get at each stop. If you are weighing a safari against a quad bike tour, read our jeep safari vs ATV guide first, mainly for the insurance points.
Elephant sanctuary visits
Samui has several elephant camps that call themselves sanctuaries, and half-day visits are listed at about ฿1,500–3,500 per adult. The word “sanctuary” is not regulated, so look at what the visit involves. Places that offer riding, shows or painting are not ones we recommend. Feeding, watching and learning about the animals is the better model. Our guide to choosing an ethical elephant sanctuary has a checklist.
These visits suit families with young children well, because they are short and close to the main beaches.
Cooking classes
A Thai cooking class usually lasts three to four hours, often starts with a market visit, and ends with you eating what you cooked. Booking-site listings run at about ฿2,000–2,600, and resort classes can cost around ฿4,500. Ask how many dishes you cook yourself versus watch, and whether transfers are included. It is a good booking for a wet afternoon.
Diving and snorkelling
Samui is a base for diving rather than a top dive site itself. Day trips go to Sail Rock, between Koh Phangan and Koh Tao, or to Koh Tao. Two-dive days are listed from about ฿2,500 to ฿6,000, depending on the boat and what is included, and PADI Open Water courses at roughly ฿12,500–18,000. The UK government’s Thailand travel advice warns that some dive schools cut corners, so ask whether there is oxygen on the boat and check the instructor’s certification.
For snorkelling only, you do not need a dive centre. Koh Tan off the south coast is the easiest reef to reach; our water activities guide covers the other options.
Koh Phangan and Koh Tao day trips
Koh Phangan is close enough to do on your own. Ferries leave from Nathon, Maenam and Bangrak and take roughly 20 to 45 minutes, at about ฿200–500 each way. Hire a driver on the other side, and check the last boat back before you set off.
Koh Tao and Nang Yuan are further out. Organised speedboat day trips are listed from about ฿1,700–2,300 per adult and take seven to eight hours, with snorkelling and the Nang Yuan viewpoint. Nang Yuan charges its own entry fee in cash, reported at anything from ฿100 to ฿250. The crossing is long and open, so skip it if you get seasick or the forecast is windy.
How to spot a good tour operator on Koh Samui
Most problems people report with Koh Samui tours come down to a handful of things that were never checked. These are the ones that matter.
- A tour business licence. Tour companies in Thailand need a licence from the Department of Tourism, usually called a TAT licence. The number should be on the website or booking page, and you can look it up with the department’s licence check at dot.go.th. Ours is 44/00252.
- Insurance. Look for “accident insurance” in the inclusions. If it is not listed, ask.
- Pickup. Check that your hotel area is covered, roughly what time you will be collected and whether villas up steep roads need a meeting point.
- Cancellation and weather policy. You want it in writing: how late you can cancel for free, and what happens if the sea is too rough (new date, refund, or both).
- Group size and boat size. Twenty people on a big catamaran feels very different from twenty on a speedboat. Ask how many guests the trip carries and whether there is a minimum to run.
- Reviews. Read the recent ones, not the average. Look at guests’ own photos, and read the two- and three-star reviews: they tell you what goes wrong on a bad day.
- Safety kit. Life jackets for every guest, in child sizes if you need them, and a first-aid kit.
A very low price is not a warning sign in itself, but it usually means something has been left out. Add the extras before you compare.
Questions to ask before booking Koh Samui tours
- What is the final price per person, with every fee included?
- Is lunch a proper meal or snacks? Are drinks included?
- Are park fees, island fees and snorkel gear in the price?
- What time is pickup from my hotel, and when will I be back?
- What language do the guides speak?
- How many guests will be on the boat or in the vehicle?
- What happens if the weather is bad, or the minimum number is not reached?
- How late can I cancel for free?
Want one tour that has the answers already sorted?
The Samui Journey 1-Day Catamaran visits the Five Islands, Koh Tan and Pig Island with hotel transfers, lunch, drinks, snorkel gear, accident insurance and the landing fee included. Free cancellation up to 24 hours before pickup, and in bad weather a new date first, then a full refund if that date is also hit. Adults ฿3,300, children (5–11) ฿1,900, under 5s free. Check dates and book or ask us on WhatsApp: +66 94 751 4988.
Where our three trips fit
We run three day trips. Each one fills a different slot in a holiday, and none of them is the right answer for everyone.
- 1-Day Catamaran (฿3,300 adult, ฿1,900 child 5–11, under 5s free). A full sea day from Bang Kao Pier on a VIP four-engine catamaran with a toilet, a water slide, banana boat (ages 5+), kayaks and paddleboards. Hotel pickup is about 9:00–9:40 AM depending on your area, and you are back around 4:30 PM. It needs at least 40 guests to sail; if that is not reached, you choose a new date or a full refund. It does not go to Ang Thong.
- Explore the Real Samui 4×4 Island Safari (from ฿1,950 adult, ฿1,650 child 5–11, under 5s free). Our land day, and the one to book when the sea is rough.
- Samui Elephant Kingdom (฿3,000 adult, ฿1,700 child, under 5s free). A half-day visit to a sanctuary we support and book guests into. We do not own it.
Our guides speak English and Chinese. We do not run diving, cooking classes, Ang Thong or Koh Tao trips, and we do not hire out the catamaran privately. For private or custom days, see our private tours page.
Fitting tours into your stay
- Book boat days early in your trip. If the weather moves one, you still have days to reschedule.
- Do not stack two long days. A full boat day followed by a 7 AM Koh Tao pickup is hard going, especially with children.
- Keep one land option in reserve for windy days, mostly from mid-October to early December.
- Need more ideas? Our list of things to do in Koh Samui covers what you can do without a tour.
FAQ
What are the best Koh Samui tours for a first visit?
A boat day to the southern islands (Five Islands, Koh Tan and Pig Island) or Ang Thong when it is open, plus one land day such as a 4×4 safari or an elephant sanctuary visit. That gives you the sea and the island’s interior without spending every day in a vehicle.
How much do tours in Koh Samui cost?
Most shared day tours are listed at roughly ฿1,300–3,500 per adult. Half-day boat trips sit at the low end, full-day all-inclusive boats and sanctuary visits at the higher end. Diving courses and private boats cost more.
Should I book Koh Samui tours in advance or on the island?
Booking a day or two ahead is usually fine, and booking online lets you read the cancellation policy first. In the busy months (December to April) popular boat days can fill, so allow a few days.
How can I check if a tour company in Thailand is licensed?
Ask for its tour business licence number and search it with the Department of Tourism’s licence check at dot.go.th. If the company cannot give a number or it does not show up, book elsewhere.
Which tours still run when Ang Thong is closed?
Trips to Koh Tan and Pig Island are outside the national park and still run when the sea is safe. Land tours, sanctuary visits and cooking classes are not affected by the closure.
Do Koh Samui tours include hotel pickup?
Most do for the main beach areas (Chaweng, Lamai, Bophut, Maenam and the west coast), but not all. Check your area is covered and ask what time to be ready.
