What to do in Ko Samui
Koh Samui is not an island where you go "just to lie on the beach".
Sure - beaches are the main reason most people come here. But if you stay here for a few days, you'll quickly discover that it's the combination of beaches, excursions to nearby islands and slightly "resort-like" comforts that makes Samui so powerful.
Koh Samui is also one of Thailand's main entertainment spots - the discos and beach clubs there are renowned, yet much nicer and more sedate than, say, Pattaya.
Below, you'll find a rundown of the activities that make the most sense on the island - without the sauce, from the perspective of someone who's dealt with it exactly the same way you have: what to actually do here that won't be boring.

Beaches: reality vs. expectations
Koh Samui will be a true paradise for beach bums and tropical enthusiasts. The local beaches are simply renowned, although quite frankly - for me there are much better places for beautiful beaches in Thailand. I can think of Krabi, for example.
The island is generally small and you can find a nice beach pretty much anywhere, just walk/drive along the coast and pick your own.
The nature of the beaches
We mostly came across beaches with the following characteristics:
- fine white sand (mostly really pleasant to walk on), some of the sand is coarser but still relatively comfortable and without large pebbles
- gradual entry into the water (ideal for non-swimmers)
- warm water all year round
- lots of resorts right on the beach
- lots of restaurants or food stalls
- water sports often available on the main beaches
- sun lounger hire but only at the resorts or restaurants
Most of the beaches are more urban and are built up with villas, resorts or restaurants.
Purely natural beaches tend to be offered by luxury gated hotel resorts. In this respect, the Thai region of Krabi is much more photogenic.
Where are the best beaches?
We travelled almost all the way around the island in our rental car and visited most of the beaches.
In general, we liked the western and northern part of the coast much better.
We found the beaches on the east and south to be narrow, far from everything, not very photogenic and the water seemed a bit dirty.
We would personally rate these beaches as the top 5 on Koh Samui:
- Bophut Beach - this beach is my personal favourite. Lots of people, very lively but beautiful walking promenade, great variety of shops and restaurants and comfortable entrance to the sea
- Chaweng Beach - the liveliest, largest range of water sports, nicest colour of water, but the most people
- Silver Beach - smaller, photogenic, "instagram" vibe, lots of people
- Coral Cove Beach - quieter, a bit wilder sea, but visually beautiful
- W Beach - visually beautiful beach at the W Koh Samui hotel we stayed at. There is also public access from the east.
π Interested in more tips on the best resorts and locations for accommodation? Check out our article Top hotels on Koh Samui.
Where are the worst beaches on Koh Samui?
Honestly:
- the east and south of the island has worse water and not much photogenic coastline - we didn't enjoy this part at all
- quiet and small bays are often prone to algae formation - typically the northern part of Chaweng
- the beach tends to be less well maintained at the cheaper resorts
π This is why it pays to sort accommodation by location.
For example, we stayed at a really nice resort called Homm Chura Samui for the first part of our stay. Great location, great value for money, but the worst beach on Koh Samui.
Where are the calmest beaches on Koh Samui?
Once you escape the main tourist areas, the difference is immediate.
I felt the most peaceful on Mae Nam and generally in the north of the island. It doesn't mean you'll be alone there, but compared to Chaweng, it's a whole different world.
Similarly, some parts of Bophut off the main promenade or smaller beaches that you don't get to "by accident of the road" but rather through the resort reception.

What is the sea like on Koh Samui?
The sea on Samui is exactly the type that is great for a holiday, but not the nicest in the world.
β What I liked:
- Warm practically all the time
- mostly calm
- beaches have mostly fine nice sand
β What didn't I like?
- The sea is not always completely clear
- the colour of the water varies depending on the location and the weather
- if there are bigger waves, the beaches are full of algae
π If you are expecting Maldives or Seychelles, you will be disappointed.
π If you want a relaxing tropical holiday, you will be happy.
When to go to Koh Samui for the beaches?
This is one of the most underrated factors in my opinion.
You can have a perfect beach and hotel, but if you arrive at the wrong time of year, the water won't be nice and the overall impression will drop.
In general:
- the best conditions are February - August.
- the weakest period is October - early January
The difference in experience is greater than the difference between beaches.
Seasons and when to go to Koh Samui
π Context of the whole of Thailand: which islands and regions to visit during the year?
Where to find empty beaches on Koh Samui?
Honestly, don't expect completely empty beaches here. Samui is a developed and densely built-up island.
The quietest beaches usually belong to the luxury resorts, so if you really want peace and quiet, you'll have to pay extra for better accommodation.
- π¨ Our tip: reviews and my photos from my stay at W Koh Samui
- π Where to stay in Koh Samui - in general
If you're looking for significantly less frequented beaches, hop on a ferry and within 40 minutes you'll be on smaller and quieter islands:
- Koh Phangan - our tips and stay experiences
- Koh Tao - we haven't visited yet
Are the beaches on Koh Samui suitable for children?
Yes - and that's why Samui is so popular with families.
Most of the main beaches have:
- Gentle entry into the water
- minimal waves
- warm sea
Koh Samui is an extra developed island with all services. De facto here everything works on a western level.
I would consider Mae Nam and Bophut to be the best for children.
Excursions to nearby islands and national parks
The island's great location is when you stop seeing Samui as just a place for a "nice beach holiday".
You can take day trips (or even multi-day trips) to the surrounding smaller islands.
We tried 3 trips, but there are more options.
Is Ang Thong Marine Park worth it?
For me, definitely yes - and I'd safely say it's the best day trip from Samui.
We were there and it met expectations exactly:
- dozens of small islands
- sights that are really worth seeing
- kayaking between the rocks
- snorkeling
- lagoon in the middle of the island
The whole day is quite intense but at the same time well organized. It is not a "tourist trap" but a real highlight of the area.
If you only have time for one activity, this will most likely be it.
- π Detailed information and our experience of the trip in the article Ang Thong Marine National Park
- π Book your trip on GetYourGuide.com
Pig Island - the perfect half day trip
A tropical island with free-roaming pigs. A bit of a quirk, but ultimately a fun experience.
We were there - and surprisingly we enjoyed it more than I expected.
- pigs on the beach (yes, really)
- a short boat ride or an adrenaline-pumping jetski ride
- combination with other stops
It's perfect as a half-day or relaxing trip when you don't want to spend all day on a boat like at Ang Thong.
If you are on Koh Samui for multiple days, for me this is a must-see. It works great as a diversion for your stay.

Does it make sense to go to Koh Phangan from Koh Samui?
The island of Koh Phangan is similar in size to Koh Samui and lies about 30 minutes by ferry from here.
For me, it definitely makes sense to visit it, but for multiple days rather than as a day trip.
Koh Phangan is completely different from Samui:
- more of a backpacker vibe
- more nature
- less "resort"
- more laid back
Most people are only familiar with the Full Moon Party, but realistically the island is interesting beyond that.
- π Our complete guide to Koh Phangan
- π How we enjoyed the Full Moon Party + practical info
- π Book your ferry - 12.go.asia
The Full Moon Party is just about the only activity that makes it worthwhile to go to Koh Phangan from Koh Samui for just a one-day detour. In fact, ferries from Koh Samui directly to Full Moon Party run all night round trip.
Does it make sense to go to Koh Tao from Koh Samui?
If you're attracted to the sea and snorkeling, then yes, by all means, take a day trip. Koh Tao is significantly smaller than Koh Phangan.
The boat ride takes about 60 minutes.
Koh Tao is a world away from Samui in terms of snorkelling:
- Clearer water
- more fish
- better conditions for snorkelling and diving
We haven't been there yet, but it's one of the most recommended things to do in the area.
However, if you want to enjoy the peace and quiet of Koh Tao's clean beaches to the max, we'd rather recommend going for 2-3 nights.
What is Koh Phaluai and does it make sense to go there?
This is more of a "hidden gem" than a mainstream trip.
Koh Phaluai lies in the Ang Thong area, but:
- it's not as touristy
- it feels more authentic
- minimum infrastructure
- you can stay overnight here - perfect for absolute tranquillity
We haven't been there yet, but if you want something less touristy than the classic tours, it can be an interesting alternative.
A trip more for those who are new to Samui.
What trips from Koh Samui to choose (quick decision)
If you want to simplify it:
- 1 trip β Ang Thong
- 1 short trip β Pig Island
- more time β Koh Phangan / Koh Tao
Nightlife, discos and beach clubs
Koh Samui has one big advantage - it's not a "party or nothing". It's not wild Pattaya, nor is it Patong.
You can have:
- A wild night in Chaweng
- a quiet evening by the sea
- a stylish beach club during the day and evening
And often you can combine it all in one stay.
But the difference between the different areas is huge. The choice of location decides more than anything else.
Find a hotel near the nightlife
Where is the best nightlife on Koh Samui?
If you're looking for the classic "party scene", you'll end up in Chaweng.
- The bars next door
- clubs open late into the night
- Lots of people, lots of noise
It's the kind of place where you go for one drink... and come back at 3am.
Fisherman's Village, on the other hand, has a completely different vibe:
- stylish bars.
- the lights, the boardwalk.
- more of an evening atmosphere than a party
Are beach clubs on Koh Samui worth it?
For me, yes - and quite a lot.
It's something in between:
- bar
- restaurant
- a swimming pool
- lounge by the beach
And you can often spend half a day there.
What are the best beach clubs on Koh Samui?
Most often recommended (and it makes sense):
- Nikki Beach β the most famous, upscale vibe
- Chi Samui β modern, stylish
- SEEN Beach Club β design + music
- Ark Bar (during the day) β more of a party atmosphere
- Coco Tam's β modern club and disco in Bophut
Each has a slightly different style - from chill to "day party".
How much do beach clubs on Koh Samui cost?
Depends on how much you want to "deal".
- Free entry (mostly)
- sun loungers β often subject to a spending fee and sun loungers on the beach often have to be booked in advance
- drinks β approx. 150-300 thb
- food β western prices
Most common model: minimum spend instead of entrance fee (but no one checks this in reality).
Are there parties on Koh Samui during the day?
Yes - and that's pretty underrated.
- pool parties
- beach parties
- DJ sets during the day
If you don't want classic clubs, this is the perfect alternative.
How does the nightlife work on Koh Samui?
It's pretty "free" - no strict schedule.
Typical evening:
- Dinner
- drink on the beach / market
- bar / beach club
- possibly disco
Everything is close and flexible and Grab/Bolt operate on Koh Samui 24/7.
Is it worth going to Koh Samui for a party?
Yes... but with expectations.
- It's not Phuket
- It's not Bali.
- It's a soft party + resort vibe.
Koh Samui is also a great starting point for a Full Moon Party on the neighbouring island of Koh Phangan.
Ideal if you want a combination: beach during the day + evening entertainment.
Where to stay for nightlife?
This is a key decision.
- Chaweng β if you want to be in the heart of the action
- Bophut β if you want evenings out but quiet for sleeping
This will fundamentally affect the whole stay.
Is the nightlife on Koh Samui safe?
Generally yes.
- minimum problems
- normal tourist precautions
What to watch out for:
- pickpockets in the crowd
- exorbitant prices in some bars
Nothing unusual compared to other destinations.
Massages
A full-body massage overlooking the sea is something you can count on at all beaches on Koh Samui.
The masseuses here are very skilled. You'll find them on every corner, all eager to greet you and offer you the best price.
How much does a massage on Koh Samui cost?
- Approx. 300 thb to 400 thb per hour / body massage
- better spa more
The price/performance ratio here is extremely good.
Night markets and food
One of the activities I enjoyed the most - and yet people often underestimate it. I love the markets and Koh Samui is full of them.
Which night markets on Koh Samui are worth checking out?
We didn't get to visit all the markets by far during our stay, but these were our favourites:
What to taste on Koh Samui?
- pad thai
- red or green curry
- mango sticky rice
- fresh seafood
The best and cheapest food I've always had was at street food.
Cooking classes
This is exactly the kind of activity we haven't tried ourselves, but I've seen it literally everywhere.
And judging by other people's reactions, it's one of the top rated experiences.
Is the cooking course on Koh Samui worth it?
Apparently yes - and quite a lot.
Typically:
- a small group of people
- buying raw materials (sometimes even a market)
- cooking several meals
- eating dinner together
It's a combination of experience + practical skills.
What will you learn to cook on Koh Samui?
Mostly:
- pad thai
- green curry
- tom yum
- mango sticky rice
This is exactly the kind of experience you'll take home and enjoy for the rest of your life.
How much does a cooking course on Koh Samui cost?
As a guide:
- Approx. 1 000 - 2 500 thb
Depends on the length of the course and the size of the group.
Does it make sense to book a cooking course in advance?
Yes - this is where booking makes sense.
- Limited capacity
- better schools tend to sell out
- often include pick-up from the hotel

Water sports
Honestly - I took water sports on Samui more as an "add on". The tradition of water sports here isn't as big as, say, Phuket, but you can still have fun here.
Unlike other islands, here you have:
- easy access (directly from the beach)
- a wide range of activities
- relatively good prices
π You can find most of it on Chaweng and Bophut, where there is also the biggest concentration of centres.
What water sports can I do on Koh Samui?
The most common combination you'll see on any major beach:
- jetski
- parasailing
- banana boat
- flyboarding
- paddleboard/kayak
- wakeboard / waterski
How much do water sports cost on Koh Samui?
The prices are surprisingly "tourist normal", not extreme.
As a guide:
- jetski β approx. 1 400-3 800 thb depending on time
- flyboard β approx. 2 000-3 500 thb
- banana boat β approx. 1 000-1 600 thb
- wakeboard β approx. 1 500-2 600 thb
- kayak rental β from 300 thb per hour
Is it worth booking water sports in advance?
Honestly - usually not.
- jetski / banana β deal directly on the beach
- prices can sometimes be negotiated
- flexibility is an advantage
But:
It makes sense to book in advance:
- organized trips
- combination packages
- jet ski safaris / longer tours, e.g. to Pig Island

Is jetskiing on Koh Samui safe?
In principle, yes, even for beginners. I just went to Koh Samui for the first time in my life on a longer jet ski trip.
However, we were unlucky with the weather and there were big waves. We still made it, but the adrenaline was almost uncomfortable in places.
I describe in detail our experience and practical info in the article Jet Ski Tour to Pig Island.
Snorkeling
This is where I had perhaps the highest expectations - and the biggest "reality check".
Is the snorkeling on Koh Samui good?
Probably not.
- The water tends to be murkier
- the corals are weaker
For a quick snorkel ok, but definitely not a highlight of the island.
Where is the best snorkeling off Koh Samui?
Simple answer: outside Samui.
- Koh Tao
- Organized trips to Ang Thong Marine National Park
π‘ The difference is really noticeable - if you enjoy snorkelling, this is a must-do: venture off the island.
Book snorkeling trips - GetYourGuide
Right on Koh Samui, the best snorkelling conditions are probably at the edges of Silver Beach and Coral Cove Beach, but you really can't compare to the Koh Tao sites.
Is diving on Koh Samui worth it?
- If you just want to try β yes
- If you want top sites β more like Koh Tao
Things to do off the beach (sights, nature, views)
This is exactly the part that people often underestimate.
Samui is not just about the beaches. But at the same time, it's not an island of "iconic sights".
It's more about a combination of smaller places that together make sense.
What to see on Koh Samui beyond the beaches?
The most common mix:
- Temples - Big Buddha, Wat Plai Laem, Red Temple
- Waterfalls - Na Muang 1, Na Muang 2
- Viewpoints - Overlap Stones, Chaweng Pagoda
- Inland jungles
None of these are "must-see world attractions" - but together they work well.
What to do on Koh Samui when you don't want to just lie on the beach?
For me, the perfect combination:
- 1 day trip (Ang Thong / Koh Tao)
- 1 day exploring the island
- evening meal / market / massage
It is this combination that makes Samui interesting.
