Why visit Koh Samui?
Koh Samui stands out for its diverse beaches and more developed infrastructure compared with many smaller Thai islands. You’ll find plenty of restaurants, accommodation, shops and transport options, while still being able to stay in much quieter areas.
The island also makes it easy to combine beach time with temple visits, waterfalls, markets, snorkelling and excursions to other islands in the Gulf of Thailand.
For additional information about the island and its attractions, you can consult the official Koh Samui guide from the Tourism Authority of Thailand.
If you’re comparing destinations on Thailand’s different coasts, take a look at our Phuket travel guide and Krabi travel guide.
Koh Samui, Koh Phangan or Koh Tao?
Of the three islands, Koh Samui is generally the easiest choice for travellers looking for a wide range of accommodation, restaurants and services. Koh Phangan offers a greater contrast between peaceful beaches, wellness retreats and party areas, while Koh Tao particularly appeals to visitors interested in diving.
When is the best time to visit Koh Samui?
Koh Samui’s climate differs from that of Phuket or Krabi. Its heaviest rainy season generally occurs later in the year.
- January to April: generally favourable conditions for beaches and outdoor activities.
- May to September: hot weather with a mixture of sunshine and showers. June to August can be a good option for visiting Thailand during the summer months.
- October and November: usually the wettest period of the year.
- December: a transitional month, with conditions that can vary from year to year.
To understand how Koh Samui’s climate compares with other regions, read our guide to the rainy season in Thailand and our article about visiting Thailand in summer.
How many days do you need in Koh Samui?
Three days are enough to discover several major attractions, but five days allow for a much more relaxed pace and give you time for a boat trip without sacrificing your beach days.
3 days in Koh Samui
- Day 1: explore your local area, enjoy the beach and spend the evening at Fisherman’s Village or in Chaweng.
- Day 2: visit Big Buddha, Wat Plai Laem, Hin Ta and Hin Yai, followed by some time at Lamai Beach.
- Day 3: discover Na Muang Waterfalls or take a boat excursion, depending on your interests.
5 days in Koh Samui
- Days 1 and 2: follow the first two days of the itinerary above.
- Day 3: explore Na Muang Waterfalls and enjoy more time on the island, rather than booking a boat excursion.
- Day 4: take a day trip to Ang Thong Marine National Park.
- Day 5: explore the quieter beaches along the northern, southern or western parts of the island.
If you have more time, consider extending your trip to neighbouring Koh Phangan or Koh Tao. You can also use our Thailand itinerary planner to organise a longer journey.

Big Buddha and Wat Plai Laem
Two of Koh Samui’s best-known religious attractions are located in the northeastern part of the island.
- Big Buddha (Wat Phra Yai): a large golden Buddha statue overlooking the Bang Rak area.
- Wat Plai Laem: a Buddhist temple complex particularly known for its multi-armed statue of Guanyin.
Both are active places of worship, so visitors should dress appropriately and behave respectfully.
Hin Ta and Hin Yai Rocks
Located near Lamai, these natural rock formations are famous for their unusual shapes. A visit is relatively quick and can easily be combined with Lamai Beach or a drive around the southern part of the island.
Na Muang Waterfalls
Na Muang Waterfalls are among the main natural attractions in Koh Samui’s interior. Water levels vary considerably depending on the season and recent rainfall.
The rocks can be slippery, especially after rain. Wear suitable footwear and take care around the pools.
Lad Koh Viewpoint
Located between Chaweng and Lamai, this viewpoint offers an easily accessible panorama of the island’s eastern coastline. Its convenient location makes it a worthwhile stop when travelling around Koh Samui.
Fisherman’s Village in Bophut
Fisherman’s Village is now one of the most popular tourist areas in northern Koh Samui. It offers restaurants, shops, cafés and markets on certain days of the week.
It’s particularly enjoyable in the late afternoon and evening, providing a different atmosphere from Chaweng.
Best day trips from Koh Samui
Ang Thong Marine National Park
Ang Thong Marine National Park consists of an archipelago of limestone islands west of Koh Samui. Day trips usually include a selection of activities depending on the operator and weather conditions, such as boat tours, kayaking, viewpoints, snorkelling or beach stops.
Access to some areas may be restricted due to weather conditions or environmental protection measures. Before booking your excursion, check the Tourism Authority of Thailand’s information on seasonal national park closures and confirm the park’s current status with your tour operator.
Koh Phangan
Koh Phangan can be explored during a separate stay or, depending on available ferry connections, as part of a day trip. The island is known for its beaches and quieter areas, as well as the famous Full Moon Party.
Koh Tao and Koh Nang Yuan
Koh Tao is particularly well known for scuba diving and snorkelling. However, a day trip from Koh Samui involves more travel time than a local excursion, so make sure you check the total journey duration before booking.

How to get to Koh Samui
By plane
Koh Samui has its own airport. Flights connect the island with Bangkok and other destinations, depending on schedules and the time of year.
If you’re travelling through the capital, our Bangkok travel guide can help you plan that part of your journey.
By ferry
Another option is to travel to Surat Thani province and take a ferry from the Donsak area to Koh Samui. Depending on the operator, ferries arrive at Nathon or Lipa Noi on the western side of the island. Check your arrival pier and onward transfer before booking, especially if you’re staying in Chaweng, Lamai or Bophut.
How to get around Koh Samui
Distances can be considerable, and the beaches are spread around the island’s coastline. The best way to get around therefore depends on where you’re staying and what you plan to visit.
- Songthaews: shared passenger vehicles operating along several main routes.
- Taxis and ride-hailing services: convenient for occasional journeys. Compare fares or agree on the price beforehand when necessary.
- Rental car: a practical option for exploring the island as a group or with children.
- Scooter: suitable only for experienced riders with the appropriate licence and insurance coverage.
Before renting a motorbike, read our practical guide to renting a scooter in Thailand.
Is Koh Samui expensive?
Koh Samui can be noticeably more expensive than some mainland destinations, especially when it comes to beachfront accommodation, taxis and high-end resorts.
However, the cost of your stay depends heavily on the area, season and level of comfort you choose. Chaweng and the main tourist areas offer accommodation across a wide price range, while luxury villas and resorts can quickly increase your budget.
For a broader estimate based on your travel style, read our Thailand travel budget guide.
Markets, food and nightlife
Markets and small local restaurants are great places to discover southern Thai cuisine beyond the tourist restaurants and hotels.
