Dense green jungle, long sandy beaches and clear water on Thailand's eastern seaboard near the Cambodian border — an island that stays slower and quieter than Phuket or Samui. This guide is built from verified facts and real visitor accounts to get you ready for your first Koh Chang trip before you board the ferry.
Koh Chang is Thailand's second-largest island after Phuket, sitting in Trat province at the far eastern edge of the country. Nearly half of it is the rainforest of Mu Ko Chang National Park, with dense green mountains running down to the sandy beaches along the west coast. This is the island for travellers who want beautiful sea without the bustle of the bigger-name resorts.
You arrive by car ferry — Koh Chang is an island with no bridge, reached by a short ferry crossing from the Trat mainland (about 30-45 minutes). That single fact is what keeps it quiet. Good sea in the dry months — November to April brings calm clear water, good snorkelling, long beaches and reliable sun. A lot in one island — on a single trip you can laze on the beach, climb to the Kai Bae viewpoint over the offshore islets, walk through the jungle to Klong Plu Waterfall, and take a boat out to snorkel at Koh Rang, where the water is clearest. See the full overview at the complete Koh Chang guide →
Koh Chang is a place to slow down, not to race around ticking off sights. Three days is the sweet spot — beach time, the viewpoint, a full snorkelling day and the waterfall all fit comfortably. If your time is tight, two days and one night works for a quick visit, but build in enough margin for the ferry both ways.
Day 1: Bus or fly to Trat, cross on the ferry, check into a west-coast beach, swim, then the Kai Bae viewpoint for sunset, seafood and a beach bar. Day 2: Klong Plu Waterfall and a beach you missed (or a half-day snorkelling trip if the sea is calm), then the afternoon ferry back to the mainland.
Add a full snorkelling and island-hopping day (Koh Rang and the southern isles, the clearest water) and the time to actually slow down. Day 1 beaches and the viewpoint, Day 2 the boat trip, Day 3 Klong Plu Waterfall, Bang Bao fishing village and a quieter beach before the ferry home. Three days fits the island's relaxed rhythm best.

November to April is the prime window: dry, sunny, clear skies, a calm clear sea, good snorkelling — and everything open, from resorts and restaurants to boat trips and beach bars. This is when most people visit. December-January and Songkran are the busiest and most expensive. Full month-by-month breakdown at when to visit Koh Chang →
May to October is the monsoon: rain, a rough sea, and snorkelling trips that often stop running, while many resorts, restaurants, dive shops and beach bars close or cut hours. Koh Chang is far quieter than Phuket or Samui in low season. The upsides are lush green jungle, full waterfalls, cheap rooms and few crowds. The ferry still runs, though crossings can be choppy. See snorkelling & island hopping →
Koh Chang is an island, reached only by car ferry from the Trat mainland — there is no train, no airport and no metro on the island. The trip is really "get to the Trat side, then cross". You choose between a cheap bus or a quicker flight into Trat — see the full guide at how to get to Koh Chang →
A bus or minivan from Bangkok (Ekkamai / Mo Chit / Suvarnabhumi) runs straight to the Trat ferry piers in about 5-6 hours for ฿250-500. Many operators sell a combined "bus + ferry" ticket all the way to the island. You then take the car ferry for about 30-45 minutes across to Koh Chang. Best for travellers who want to save money and aren't in a rush.
Fly from Bangkok (mostly Don Muang) to Trat Airport (TDX, Bangkok Airways) in about an hour, then take a van to the pier and the car ferry. This cuts the journey to roughly half a day compared with the bus. Best for travellers short on time who don't mind paying more; airport-transfer packages can be booked ahead.
The island has no metro, no train, and Grab is essentially unavailable. The way most visitors move is the shared songthaew (red taxi) running along the west-coast beach road. You flag one down and pay a set per-person fare in stages, roughly ฿50-150 by distance, more at night or for a private charter. Full guide at getting around Koh Chang →
A rented scooter gives you the most freedom, but it comes with a real warning — Koh Chang has some very steep hills, especially between Kai Bae and Lonely Beach, and inexperienced riders crash a lot. Always wear a helmet, check the brakes before you set off, walk the steepest hills if you are unsure, and never ride at night or after drinking. Car and jeep rental, plus boat taxis between beaches, are also options.
The single most important choice on Koh Chang is which beach you book, because they run one after another along the west-coast road, each with a different feel and price point. Pick one beach and stay put. Full neighbourhood guide at where to stay on Koh Chang → or the beaches guide →
The main, longest-developed beach, with the most restaurants, bars, shops and hotels — everything walkable, great sunsets, a busy-but-fun feel. Ideal for first-timers who want it all on the doorstep. See White Sand Beach →
A long, laid-back central beach split by lagoons and khlongs, calmer and more spread out, with mid-range to upscale resorts. Good for couples and families who want quiet with food still nearby; there's an estuary you can kayak. See Klong Prao Beach →
A relaxed beach with little offshore islands in front, close to the famous Kai Bae viewpoint and its classic sunset photo. Good value. The beach is rocky and shallow at low tide, so check the tide times. See Kai Bae Beach & viewpoint →
The backpacker and party beach, with beach bars and fire shows and the cheapest rooms on the island. A fun night-time scene and an easy place to meet people. ⚠️ The road here is steep, so take extra care if you're riding a scooter.
Bang Bao fishing village has a pier of over-water seafood restaurants, dive shops and a lighthouse walk. The south of the island is quiet and remote — you'll need transport, but it suits travellers escaping the bustle for fresh seafood. See day trips →
Koh Chang has several beaches and a lot of nature, but for a first visit these are the core — the things that best explain why the island is worth the trip. Full details at Koh Chang attractions → or day trips and activities →
The west-coast beaches are the heart of Koh Chang. White Sand is the lively all-rounder, Klong Prao is long and calm, Kai Bae is chilled and near the viewpoint, and Lonely Beach is the party spot. Pick the beach that matches your style and spend real time there.
Koh Chang's most classic photo spot, looking down over the little islands strung out in the sea — best at sunset. It sits just south of Kai Bae beach and charges a small entry or parking fee. ⚠️ The road here is steep, so take care on a scooter.
The island's main waterfall, inside Mu Ko Chang National Park, reached by a short jungle walk to the fall and its swimming pool. Fullest in and after the rains. There's a national-park entry fee, and it sits near Klong Prao. ⚠️ The rocks are slippery — no jumping. See Klong Plu Waterfall →
Koh Chang's signature day out is a boat to the southern marine islands — Koh Rang has the clearest water, with Koh Wai, Koh Yuak and Koh Mai Si nearby. The typical 4-5-island speedboat or big-boat tour includes a park fee. ⚠️ In the rainy season (May-Oct) trips often stop because the sea is rough. See snorkelling & island hopping →
Almost half the island and the southern snorkelling islands sit inside Mu Ko Chang National Park — beautiful nature, but it comes with a duty to look after it.
There are park entry fees at Klong Plu Waterfall (around ฿200 for foreigners, less for Thais) and on the southern marine boat trips (Koh Rang and others). Fees can change, so check the latest before you go. Park etiquette: no litter, don't touch or stand on the coral, and don't feed the fish bread.
Koh Chang ("Elephant Island") has elephant camps, though there are no wild elephants here. Choose to observe, feed and bathe elephants rather than ride them — riding carries real animal-welfare concerns. Pick a camp that treats the elephants well and lets them be elephants. See day trips →
Koh Chang is a seaside island, so the standout is fresh seafood — especially at the Bang Bao fishing village — alongside central-Thai cooking and the beach-shack dining on each beach. Full guide: Koh Chang food guide →
Every visitor agrees seafood is the thing to eat on Koh Chang. The seafood restaurants at Bang Bao village sit over the water — fish, prawns, crab and squid straight off the boats, grilled, steamed or in curry, priced by weight and size. Check the price before you order. See Koh Chang seafood →
Every beach has shacks and small Thai cooked-to-order spots — pad thai, tom yum, fried rice and the usual curries, friendlier on the wallet than the resort restaurants. White Sand Beach and the Klong Son area have evening food markets and street stalls. See Koh Chang food guide →
Koh Chang nightlife is mellow — not Phuket or Samui. Lonely Beach is the main party beach with bars and fire shows; White Sand and Kai Bae have chilled sunset bars and live music; elsewhere it's an early night. Much of it closes in low season. See beach bars & nightlife →
Koh Chang has coffee spots with sea and jungle views dotted along the west coast, plus hillside cafés that look out over the water — a slow-island brunch culture made for a long, lazy morning. See Koh Chang cafés →
Koh Chang works for a range of budgets — from cheap huts on Lonely Beach to upscale resorts on Klong Prao and White Sand. The big-ticket items are getting there (bus plus ferry), the snorkelling tour and the national-park fees. Full breakdown: Koh Chang trip budget guide →
| Level | Accommodation/night | Food/day | Approx. total/day |
|---|---|---|---|
| Budget | ฿400–900 hut or small guesthouse (Lonely Beach) | ฿300–600 | ฿900–1,800 |
| Mid-range | ฿1,500–3,500 mid resort (Kai Bae / Klong Prao / White Sand) | ฿600–1,200 | ฿2,500–5,500 |
| Comfort | ฿4,000–12,000+ beachfront resort | ฿1,200–3,000+ | ฿6,000–18,000+ |
The big items to budget for: getting there (bus + ferry ฿300-600 per person, or flying to Trat plus the van and ferry), the ferry fare (per person and per car), the Koh Rang snorkelling tour, scooter rental (mind the steep hills), national-park fees (Klong Plu / Koh Rang), and seafood dinners.

The most common mistake is booking in the rainy season (May-Oct) and then finding the snorkelling trips stopped, restaurants and bars shut, and the island far quieter than expected. For clear water and everything open, come in the dry season (Nov-Apr). If you do visit in the wet months, confirm with your hotel that it's open and keep a rainy-day backup.
You reach Koh Chang by boat, so allow time for the ferry on the way out and back. It runs through the day, but the last crossings are late afternoon to early evening, with fewer in low season. On departure or onward-travel days, build in enough margin for the ferry, the drive to the mainland and the trip to the airport.
Koh Chang has some very steep hills, especially between Kai Bae and Lonely Beach, and inexperienced riders crash often. Wear a helmet, check the brakes before you go, walk the steepest sections if you're unsure, and never ride at night or after drinking. If you aren't used to steep roads, take the shared songthaew instead.
There are ATMs on the island, but they cluster around the main beaches and charge high fees. Small shops, some seafood spots and the songthaew take cash only — withdraw enough before you cross, and sort out a SIM or eSIM in advance, since the signal is patchy in the jungle and on the quiet beaches. See Thailand SIM / eSIM guide →
Seafood on Koh Chang is priced by weight and size, and some spots in tourist areas charge high. Look at the price board, pick your catch, watch it weighed in front of you, and confirm the total before it's cooked. Full method at eating seafood on Koh Chang →
Koh Chang is in the tropics and the sun is strong — you can burn even on a cloudy day. Pack sunscreen, a hat and sunglasses, drink plenty of water, and stay in the shade around midday. For water activities use reef-safe sunscreen, and check the tide times, since some beaches (Kai Bae) are shallow and rocky at low tide.
