Ko Samui travel guide: areas, getting around and when to go

Ko Samui is best visited from February to September, with July and August being particularly good months for a beach holiday. Unlike Phuket and Krabi, the island gets its heaviest rain between October and December, with November usually the wettest month. For your stay, choose Chaweng for nightlife and convenience, Lamai for a more relaxed beach atmosphere, or Bophut for boutique hotels and Fisherman's Village. Getting around is easiest by Grab, local songthaews or taxis, although taxi fares can be expensive. You can fly directly from Bangkok to Samui or save money by flying to Surat Thani and continuing by bus and ferry.

Is Ko Samui for you, and how long to stay

Ko Samui is one of Thailand's most popular island destinations, known for its palm-lined beaches, luxury resorts, relaxed beach bars and a good choice of restaurants. Unlike many other Thai islands, Samui has its own airport, making it relatively easy to reach from Bangkok.

The island offers something for different types of travellers, from couples looking for a romantic getaway to families wanting a comfortable beach holiday. You can spend your days exploring temples, visiting local markets, relaxing on the beach or taking boat trips to nearby islands.

Plan to stay around 4–7 days to enjoy the main beaches, explore the island and take a day trip. If you want to visit Ko Phangan or Ko Tao as well, consider adding a few extra days.

When to go: Samui's rain comes later than the Andaman side

Ko Samui has a different weather pattern from Phuket and Krabi. While the Andaman coast generally experiences its rainy season between May and October, Samui gets most of its rain between October and December.

This makes the island a good alternative during the middle of the year, particularly in July and August.

February to September: The better months to visit

February to September is generally the drier period. February and March tend to have the least rainfall, while July and August are also good months for a beach holiday. April and May can be particularly hot, with temperatures often reaching 32–33°C.

October to December: Rainy season

Rainfall increases from October and reaches its peak in November. November is typically the wettest month, with an average of around 445 mm of rain.

During this period, rough seas and strong waves can affect swimming conditions and boat trips. Always check local weather and beach warning flags before heading into the water.

January: A transition month

January is generally drier than November and December, but occasional rain is still common. Conditions usually improve as the month progresses.

Where to stay: which area suits you

Choosing the right area can make a big difference to your Samui holiday. Each part of the island has a different atmosphere, so think about what you want from your stay before booking.

Chaweng – Best for first-time visitors and nightlife

Chaweng is the island's busiest beach area, with a wide choice of hotels, restaurants, shops and nightlife. It is a convenient base if you want everything within easy reach, but it can get noisy, especially in the evenings.

Lamai – Best for a relaxed beach holiday

South of Chaweng, Lamai offers a more laid-back atmosphere while still having plenty of restaurants, bars and accommodation. It is a good middle ground for travellers who want beach life without staying in the busiest part of the island.

Bophut – Best for couples and families

Bophut is known for Fisherman's Village, where traditional shophouses sit alongside boutique hotels, restaurants and beachfront bars. It has a more relaxed atmosphere and is a good choice for couples and families.

Maenam – Best for quiet stays

Maenam has a long, quieter beach and a more peaceful atmosphere. It is a good option if you want to slow down and spend more time relaxing. The area is also convenient for ferries departing from Pralarn Pier.

Choeng Mon – Best for upscale resorts

Located in the north-east, Choeng Mon has smaller bays, luxury resorts and a quieter atmosphere than Chaweng. It is a good option for travellers looking for a comfortable beach escape.

West coast – Best for sunsets and a slower pace

Areas such as Lipa Noi, Taling Ngam and Nathon offer a quieter side of Samui, with beautiful sunset views and fewer crowds. They are better suited to travellers who do not mind being further away from the island's main nightlife and shopping areas.

Getting to Ko Samui and from the airport

There are several ways to reach Ko Samui from Bangkok, depending on your budget and how much travel time you have.

By plane: The fastest option

Flying directly to Samui Airport (USM) is the easiest way to reach the island. Bangkok Airways operates most flights, and the journey from Bangkok takes approximately 1 hour and 5 minutes.

The main disadvantage is the price. Flights to Samui are often more expensive than flights to other destinations in southern Thailand.

Via Surat Thani: A budget-friendly alternative

If you want to save money, fly from Bangkok to Surat Thani Airport (URT), then take a bus or minivan to the ferry pier and continue by boat to Samui.

You can book combined bus-and-ferry tickets, which make the journey easier to organise. However, allow several additional hours for transfers and the ferry crossing.

By train: A slower but scenic option

Trains from Bangkok to Surat Thani depart from Krung Thep Aphiwat Central Terminal. You can choose a daytime journey or an overnight sleeper train, then continue to Samui by bus and ferry.

This is a good option if you enjoy train travel and want to avoid flying.

By bus and ferry

Several operators offer combined bus-and-ferry journeys from Bangkok to Samui. It takes longer than flying, but can be a practical option for travellers on a tighter budget.

Getting from Samui Airport to your hotel

You can arrange an airport taxi, shared minibus or private transfer. Ride-hailing services are another option, but pickup arrangements and driver availability can vary.

Getting around: songthaews, taxis, apps and scooters

Ko Samui does not have an extensive public transport network, so choosing how to get around is important.

Songthaews: These shared pickup trucks are one of the more affordable ways to travel between popular areas. They operate mainly along the main roads, and you should agree on the fare before getting in.
Taxis: Taxis are available across the island, but most do not use meters. Always confirm the price before starting your journey.
Grab: Grab operates on Samui and is useful for checking fares before booking. However, driver availability can be limited in some areas.
Bolt: Availability is less reliable, so do not depend on it as your only transport option.
Scooters: Renting a scooter gives you more freedom to explore the island. However, Samui has steep hills, winding roads and busy traffic. You need the correct motorcycle licence and an International Driving Permit covering motorcycles. Always wear a helmet and check your insurance before riding.

If you are not an experienced motorcycle rider, using taxis or arranging a private driver is a safer way to explore.

Money and rough daily costs

Ko Samui is generally more expensive than neighbouring islands such as Ko Phangan and Ko Tao, particularly when it comes to accommodation, transportation and flights.

Your daily budget will depend on where you stay and how you spend your time.

Budget: Guesthouses, local restaurants and shared transport.
Mid-range: Comfortable hotels, restaurant meals and occasional taxi or Grab rides.
Luxury: Beachfront resorts, private transfers, fine dining and organised tours.

One thing to budget for is transportation. Taxi fares can add up quickly, especially if you travel between different beaches every day.

Keep some cash with you for local markets, street food and songthaews. ATMs are widely available, although foreign bank cards may incur withdrawal fees. If an ATM offers to convert the withdrawal into your home currency, choosing Thai baht is generally the better option.

Staying safe and polite: the sea, jet skis and the roads

Ko Samui is a popular holiday destination, but there are a few things worth knowing before you arrive.

Swimming and beach safety

Pay attention to red flags on the beach. They indicate dangerous swimming conditions, and you should not enter the water when they are displayed. This is particularly important during the rainy season, when waves and currents can become stronger.

Jellyfish

Box jellyfish have been reported in the waters around Samui and neighbouring islands. Follow local beach warnings, avoid swimming where warnings have been issued and use designated protected swimming areas where available.

If someone is stung by a suspected box jellyfish, pour vinegar over the affected area for at least 30 seconds, do not rub the skin and call for emergency medical assistance (1669).

Jet ski rentals

If you rent a jet ski, photograph and video the vehicle from every angle before using it. Check for existing damage and agree on the rental conditions. Never leave your passport as a deposit.

Road safety

Roads can be steep, winding and slippery during rainy weather. If you rent a scooter, make sure you have the correct licence, appropriate insurance and a helmet.

Temple etiquette

When visiting temples such as the Big Buddha, dress respectfully by covering your shoulders and knees. Remove your shoes before entering designated temple buildings.

Emergency numbers:

Tourist Police: 1155
Medical emergency: 1669

Local tips: markets, temples and the quiet side

Beyond the beaches, Ko Samui has plenty of places worth exploring.

Fisherman's Village Walking Street

Located in Bophut, Fisherman's Village is one of the island's best-known evening spots. Its Friday walking street is particularly popular, with food stalls, local crafts, souvenirs and live entertainment.

Big Buddha and Wat Plai Laem

These two temples are located close to each other in the north-east of the island. The Big Buddha is one of Samui's most recognisable landmarks, while Wat Plai Laem is known for its colourful statues and distinctive architecture.

Hin Ta and Hin Yai Rocks

Located near Lamai Beach, these unusual rock formations are also known as Grandfather and Grandmother Rocks. They are an easy stop if you are exploring the southern part of the island.

Na Muang Waterfalls

Na Muang has two waterfalls surrounded by tropical greenery. They offer a change of scenery from the beaches, although paths can become slippery after rain.

Sunset on the west coast

For a quieter evening, head towards Lipa Noi or Taling Ngam. The west coast is a lovely place to watch the sun set over the Gulf of Thailand.

Island trips: Ang Thong, Ko Phangan and Ko Tao

Ko Samui is also a convenient starting point for exploring other islands in the Gulf of Thailand.

Ang Thong National Marine Park

Ang Thong is an archipelago of around 40 limestone islands, known for its emerald lagoon, beautiful viewpoints, kayaking and snorkelling.

Most visitors explore the marine park on a full-day boat trip from Samui. However, the park closes for part of the monsoon season each year, so check the official park announcement before planning your visit.

Ko Phangan

Ko Phangan is a short ferry ride from Samui and offers a different atmosphere, with quiet beaches, jungle-covered hills and beachside cafés. It is also famous for the monthly Full Moon Party at Haad Rin.

It works well as a day trip, although staying a few nights gives you more time to explore the island.

Ko Tao

Ko Tao is particularly popular with divers and snorkellers thanks to its clear waters, coral reefs and marine life. The island also has several beautiful viewpoints overlooking its bays.

The boat journey takes longer than the trip to Ko Phangan, so staying overnight is a better option if you want to explore beyond the main beaches.

Ferry departures and journey times depend on the operator and weather conditions. During the monsoon season, services may be delayed or cancelled due to rough seas.
