Koh Chang Travel Guide: Beaches, Waterfalls & Jungle Treks

Phuket and Samui are busier and pricier than ever in 2026, and many travellers want a Thai island that still feels wild without a flight and a long transfer. Koh Chang fits that need. It sits in Trat province near the Cambodian border, about 315 km from Bangkok, and it is covered in rainforest. The catch is that the island is hilly, has no complete ring road, and shuts down partly in the rainy season, so a little planning matters.

What Makes Koh Chang Different

Koh Chang is Thailand’s third-largest island, and most of it lies inside a national marine park. Steep green mountains drop almost straight into the Gulf of Thailand. Development is squeezed into thin strips along the west coast, while the interior stays jungle. You get hornbills in the trees, hanging vines over waterfall pools, and cicadas so loud they sound like machinery by late afternoon.

The vibe is relaxed and more outdoorsy than party-focused. Families, hikers, divers, and backpackers all share the island, and the pace is slower than on Phuket.

Best Beaches by Area

• White Sand Beach (Hat Sai Khao): The longest and busiest stretch, with the most restaurants, bars, and shops. Good if you want everything within walking distance.
• Klong Prao Beach: A long, quieter beach with shallow, calm water. A good middle ground for couples and families.
• Kai Bae Beach: Smaller and relaxed, with easy swimming and sunset views over the islands.
• Lonely Beach: Backpacker territory with cheap huts, beach bars, and a younger crowd. The beach itself is small, but the social scene is strong.
• Bang Bao: A fishing village built on stilts. It is more about the pier, seafood, and boat departures than swimming.

Water clarity is decent but not Andaman-level. Swim in the dry season, when the sea is calmer and clearer.

Waterfalls Worth the Walk

Klong Phlu is the most popular, with a wide pool where you can swim under a curtain of cool water. Go early, before tour groups arrive around 10:00. Than Mayom has three tiers, and its rocks carry royal initials left by Thai kings who visited. It is less crowded and feels more like a nature walk.

Khlong Nonsi is the most adventurous option. You reach it by a longer jungle path, and the pool is deep and quiet. Park entry for foreigners is usually around 200–300 THB at the main falls, so carry cash. Waterfalls flow strongest from July to November, but in the driest months, February to April, some shrink to a trickle.

Jungle Treks and Boat Trips

Trails here are humid, slippery, and steep. The air is thick with the smell of wet earth, and the light inside the forest turns green and dim. Guides cost around 800–1,500 THB for a half-day trek and are worth it for longer routes, such as hikes between waterfalls or to viewpoints in the interior. Wear shoes with grip, not flip-flops.

Boat trips head to Koh Wai, Koh Rang, and the Koh Mak area for snorkelling, usually costing 800–1,300 THB with lunch. Kayaking around Salak Kok’s mangroves, on the island’s quieter east side, is a calm alternative to busy beaches. If you want elephant encounters, choose a sanctuary that offers observation only, with no riding and no shows.

Where to Eat

Seafood is the main event. At Bang Bao, restaurants line the wooden pier, and you can eat grilled barracuda or crab curry while fishing boats bump gently against the posts. Salak Phet, on the quieter southeast coast, is known for fresh crab and fish, with a calmer atmosphere and fewer tourists.

On White Sand Beach and Kai Bae, small family kitchens serve pad kra pao and green curry for 80–150 THB. At Lonely Beach, cheap noodle stalls and late-night food carts fill up after dark. For the best value, eat where Thai families are eating and check prices by weight before ordering seafood.

Getting to Koh Chang

The standard route is by road to Trat, then a ferry. From Bangkok’s Ekkamai (Eastern) Bus Terminal, buses and minivans run to Trat or directly to Laem Ngop pier. The trip takes 5–6 hours and costs roughly 250–400 THB by bus, or more by minivan. There is no passenger train to Trat, so road transport is the main option.

Bangkok Airways flies from Suvarnabhumi to Trat in about an hour, with fares typically from 2,500 to 5,000 THB. From the airport, a taxi or shared van takes around 40 minutes to the ferry pier.

The car ferry from Ao Thammachat pier to the island takes 30–45 minutes and costs about 80–120 THB per person. Ferries run roughly every 30–45 minutes from early morning until evening. Your bus or minivan ticket may include the crossing, so check before you buy.

Getting Around the Island

One main road follows the west coast from the ferry landing to Bang Bao. Another road links the east coast, but the two do not form a complete loop.

• Songthaews: Blue pickup trucks run along the west coast road. Expect 100–300 THB per person depending on distance, and fewer rides after dark.
• Scooters: About 250–400 THB per day. The hills are steep and the curves are sharp, and crashes are common. Rent only if you have experience, and always wear a helmet.
• Taxis and resort transfers: Useful for late arrivals and for reaching trailheads. Agree on the price first.

2026 Budget Reality

Koh Chang is cheaper than Phuket or Samui, though high-season prices (December to February) rise noticeably.

• Budget (about 1,000–1,800 THB per day): Fan bungalow or dorm at 400–900 THB, meals at 60–120 THB, songthaew rides, and occasional scooter rental.
• Mid-range (about 3,000–5,500 THB per day): Air-conditioned beachfront room or small resort at 1,500–3,500 THB, restaurant meals at 150–400 THB, a snorkelling trip, and a guide for one trek.
• Comfortable (about 7,000–12,000 THB per day): Pool resort at 4,000–9,000 THB, seafood dinners at 500–1,200 THB, private driver or taxi transfers, and private boat or guided tours.

Best Season and 2026 Practical Tips

The best time to visit is November to February, when skies are clearer and temperatures sit around 24–32°C. March to May is hot and dry, and waterfalls are weaker. June to October is the wet season. Koh Chang gets heavy rain, seas are rough, and some resorts close in September and October, but prices fall and the jungle is vivid.

Since May 2025, most foreign visitors must complete the Thailand Digital Arrival Card online before arriving, so do it before you travel. Entry rules and the length of visa-free stays can change, so confirm both with official sources before you book. Carry cash for waterfall fees and small restaurants, since card acceptance outside main beach areas is patchy. Bring reef-safe sunscreen and a rain jacket in any season.

Frequently Asked Questions

How many days do you need on Koh Chang?

Three nights is the sweet spot. That gives you one day for beaches, one for a waterfall and jungle walk, and one for a boat trip to the outer islands. If you add Koh Wai or Koh Mak, plan five to six nights.

Is Koh Chang worth visiting compared with Phuket or Samui?

Yes, if you want jungle, waterfalls, and fewer crowds. Koh Chang is greener and cheaper than Phuket or Samui, and it is closer to Bangkok by road. The trade-off is that its beaches are less polished, and the water is not as clear as the Andaman Sea.

What is the best month to visit Koh Chang?

November to February is best, with dry weather and temperatures around 24–32°C. Waterfalls still flow in November and December. June to October is the rainy season, with rough seas, cancelled boat trips, and some resorts closing, but prices drop sharply and the jungle is at its greenest.

Can you get around Koh Chang without a scooter?

Yes. Shared songthaews run along the west coast road during the day, and most resorts can arrange taxis. Fares are 100–300 THB depending on distance. Scooters are cheaper for several trips, but the steep, curvy roads cause many accidents every year, so ride only if you are experienced.

How do I get from Bangkok to Koh Chang?

Take a bus or minivan from Bangkok’s Ekkamai Eastern Bus Terminal to Laem Ngop pier in Trat, about 5–6 hours, then a 30–45 minute car ferry to the island. Total cost is roughly 400–800 THB. Bangkok Airways also flies to Trat, followed by a transfer to the pier.
