Stay first. Then what to do.
Most first-timers do best on White Sand Beach or Klong Prao. Families love Kai Bae. Want a party? Try Lonely Beach. Want peace? Head to Klong Kloi or the east coast. Tap an area, or if you're not sure, use the quick picker below.
Two quick taps and we’ll match you to the right part of the island.
A simple solo plan for Koh Chang: stay on White Sand Beach for the first night, move to Lonely Beach if you want a social scene, or Bailan and Klong Kloi for quiet, and hop on a snorkelling boat to meet people.

The easiest landing spot. It is the first beach from the ferry pier, with the most restaurants, bars, ATMs and songthaews.

The island’s backpacker hub, with hostels, beach bars and fire shows. The easiest place on Koh Chang to meet people.

Wooden bungalows over the water at Bailan, or a chilled beach in the far south at Klong Kloi. Great for reading and switching off.

Group boats from Bang Bao visit Koh Wai, Koh Rang and the small islands to the south. A fun, easy way to meet other travellers.

Shared songthaews (pick-up taxis) meet the ferry and run up and down the west coast. Scooters are easy to rent, but the hills south of Kai Bae are steep.

Lonely Beach has the best choice of hostels and cheap bungalows, and Pajamas at Klong Prao is a stylish budget pick.

Koh Chang is about 5–6 hours from Bangkok by road and ferry, so it fits well after Pattaya or Koh Samet. Koh Kood and Koh Mak are a short boat ride away.

White Sand Beach, or Hat Sai Khao, is the first big beach you reach from the ferry pier and the busiest part of Koh Chang. The main road behind it is lined with restaurants, bars, 7-Elevens, massage shops and tour desks, so everything is within walking distance. The north end has the best sand and the biggest resorts, and the south end is quieter, with a rockier shore. In the evening, restaurants put tables out on the sand for seafood barbecues, and some bars have fire shows.

Planning when to visit Koh Chang? The dry season, from November to April, is the best time. From about June to September Koh Chang is one of the wettest islands in Thailand, and some places close. Here’s a simple guide.
Quick pick: Want the best weather → aim for November–February. Want lower prices → try May or October. Want full waterfalls → go just after the rains, in October or November. Want to avoid crowds → skip Christmas–New Year and Songkran.
Best: November to April · Rainy season: roughly May to October
November to February is cool, dry and sunny. March to May is very hot. From about May to October the south-west monsoon brings heavy rain, especially from June to September, when there can be days of rain in a row.
Effect on travel: In the rainy season the sea on the west coast can be rough, some boat trips stop, and some restaurants and bungalows close. The waterfalls are at their best.
Best areas in the rainy season: Kai Bae and White Sand Beach, with plenty of restaurants and resorts with pools.
💡 In the rainy season, book boat trips last-minute, on a calm, sunny day.
Every Friday evening to Sunday, plus Thai public holidays
Koh Chang is a popular escape for Thai families from Bangkok on long weekends and public holidays. The ferry gets busy, and hotel prices go up. Christmas, New Year and Songkran are the busiest times of all.
Effect on travel: There can be queues for the ferry, rooms sell out and many hotels ask for a minimum stay on holidays.
Best areas when it’s busy: Klong Kloi and the east coast stay calmer than White Sand Beach.
💡 Avoid arriving on a Friday of a Thai long weekend if you can.
Mid-April (usually 13–15 April)
Thailand’s biggest festival. Koh Chang gets very busy with visitors from Bangkok, and there are water fights along the main road on White Sand Beach. Fun if you want to join in; tiring if you want a quiet holiday.
Effect on travel: Boats and hotels fill up, prices rise, and you will get wet whenever you go out.
Best areas during Songkran: White Sand Beach for the party; the east coast or Klong Kloi if you want to stay dry.
💡 Book early, and carry a waterproof pouch for your phone.
| When | What happens | Effect on travellers |
|---|---|---|
| November – February | Cool, dry season (best weather) | Sunny and dry, pleasant temperatures, busiest with foreign visitors — book early |
| March – May | Hot season | Very hot and mostly dry, good beach weather; Songkran in mid-April is very busy |
| May – October | Rainy season | Heavy rain at times, rough seas on the west coast, very quiet and low prices |
| Thai long weekends | Thai holidaymakers | Busy ferry, full hotels and higher prices |
| April | Songkran | Water fights, very busy boats and beaches, higher prices |
| November (full moon) | Loy Krathong | Candle-lit krathongs floated on the sea |
| Late December | Christmas & New Year | Peak prices and crowds, fireworks on the beaches |
Planning rule: On Koh Chang, the season matters most. Come between November and April for sunshine and calm seas, and book early for Christmas, New Year and Songkran.
It can be, if you like it quiet. May and October are usually fine, with sunny spells and low prices. From June to September it can rain for days, the sea gets rough and some places close.
At least three nights. The journey from Bangkok takes most of a day, and the island is big, with lots to see.
Yes — at weekends, on Thai public holidays, and especially over Christmas, New Year and Songkran. Book as early as you can for those dates.
Tap any tip for the short version. Practical stuff that saves you a bad first day.
Shared songthaews (open pick-up taxis) meet the ferry and run up and down the west coast — expect about 100–200 baht each, depending on how far you go. Ask the price before you get on.
Scooters cost about 250–400 baht a day. The road south of Kai Bae has some of the steepest hills in Thailand, so only ride if you are experienced. Wear a helmet, take photos of the bike first, never leave your passport as a deposit, and check that your licence and travel insurance cover you.
White Sand Beach is the easiest first base, with the most restaurants, bars and shops, and it is closest to the ferry. If you want it calmer, Klong Prao has a long, quiet beach and good resorts, and Kai Bae is great for families and food.
Take a bus from Bangkok’s Eastern Bus Terminal at Ekkamai to Trat or the Ao Thammachat ferry pier, or a minivan or taxi. The car ferry to Ao Sapparot on the island takes 30–40 minutes. The whole trip takes about 5–6 hours. You can also fly to Trat.

Minivans with combined ferry tickets run from Pattaya every day (about 4–5 hours in total), or take a private taxi to the Ao Thammachat pier and the ferry across.
There is no fee to land on Koh Chang. Foreign adults pay about 200 baht in cash at national park gates, such as the waterfalls. Fees can change, so carry a little extra cash.
Car ferries from Ao Thammachat usually run from about 6:30 am to 6:30 pm. If you arrive later, you will need to stay the night on the mainland, so try to reach the pier by late afternoon.
November to April is the best time, with dry, sunny days and calm seas. From June to September Koh Chang gets a lot of rain, the sea can be rough and some places close.
Christmas and New Year, Songkran in mid-April and Thai long weekends. Book hotels early for these dates.
Not on the west coast. Shared songthaews run between the beaches. Scooters are easy to rent and handy for the east coast, but the hills south of Kai Bae are very steep, so only ride if you are experienced, and never leave your passport as a deposit.
Yes. Kai Bae and Klong Prao have calm water and family resorts with big pools, and children love the waterfalls and snorkelling boats.
Hotel prices on Koh Chang change a lot between weekdays and weekends, by season and with special offers, so a fixed price would often be wrong. Tap Booking.com, Agoda, Expedia or Trip.com on any hotel to see today’s live price in your own currency. Weekends, Thai holidays, Christmas, New Year and Songkran are the most expensive times.
