Waterfalls in the jungle, reefs off Koh Rang, a fishing village on stilts and a sunset every single evening. Here is how we would spend your days, slowly.
Koh Chang is a big, green, mountainous island in the far east of the Gulf of Thailand. Most of its interior is protected rainforest inside Mu Ko Chang National Park, the west coast is a chain of beaches facing the sunset, and the east coast is fishing villages and mangroves. You could rush it. We suggest you don't.
This guide is written from our deck on Lonely Beach, on the south-west coast, where almost everything below is an easy ride away. Pick two or three things, leave plenty of space for the hammock, and let the island do the rest.
1. Start with the sunset
The whole west coast faces the open sea, so every beach here gets a sunset over the water. On the deck at Paradise Cottage it happens right in front of you: the sky turns gold, then orange, then pink, and the longtail boats go dark against it. Order something cold at the bar, claim a sala, and you have done the single best thing on Koh Chang before dinner. It is free, and it happens nearly every night.
On Lonely Beach the sun sets at around 18:00 today. Be on the deck twenty minutes early for the best colour, and stay for the afterglow.
2. Swim under a jungle waterfall
Koh Chang's mountains catch a lot of rain, and all of it has to come down somewhere. Klong Plu, on the west coast at Klong Prao, is the classic: a forest walk ending at a high fall with a deep, cool pool to swim in. It opens 08:00 to 16:30. Than Mayom, on the east coast, opens 09:00 to 16:30, and one national park ticket (฿200 for foreign visitors) covers both on the same day. Klong Neung and Khiri Phet are free and feel wilder.
Go early, before the tour groups, and go during or just after the rainy season when the water is strongest. Everything you need is in our waterfall guide.
3. Snorkel the reefs around Koh Rang
The clearest water near Koh Chang is to the south, around Koh Rang, a protected marine park. Day trips leave Bang Bao or Kai Bae around 09:00 to 09:30 and reach the reefs in 30 to 60 minutes. The marine park fee (฿200) is usually paid on top of the trip, and fins rent for around ฿100 if they are not included. Cheaper three-island trips head for the Koh Wai area, leaving about 10:30 and returning around 16:00.
The tour desk at the resort can book a boat for you. Read how the trips work before you choose.
4. Wander the Bang Bao pier
At the southern end of the west coast road, Bang Bao is a fishing village built on stilts over the water. Its long wooden pier is lined with shops, cafes and seafood restaurants where the day's catch sits on ice out front and you choose dinner by pointing. Come for a late lunch, wander to the end of the pier, then head back up the coast in time for sunset. It is also where many boat trips begin.
5. Kayak the mangroves at Salak Khok
Over on the quieter east coast, the community of Salak Khok runs an ecotourism project in its mangrove forest. Rent a double kayak (around ฿200 an hour) and paddle between the roots, or ride in a traditional rowboat with someone from the village. The money stays in the community, the herons stay in the trees, and you see a side of Koh Chang most visitors miss.
6. Find the quiet south-east
Salak Phet, in the island's south-east corner, is a long bay of stilt houses, fishing boats and seafood restaurants over the water. It feels a world away from the beach strip. Pair it with Khiri Phet waterfall nearby, which is free, and with Salak Khok's mangroves for a full east coast day.
7. Ride up to a viewpoint
The west coast road climbs and dips over steep headlands, and the high points between the beaches open onto bays and islands stretching south. The viewpoint on the hill above Kai Bae, just north of Lonely Beach, is the famous one, and late afternoon is golden there. If you rent a motorbike, take the hills slowly: they are steep and the bends are tight. A songthaew taxi is a fine alternative.
8. Slow down on purpose
Lonely Beach has daily yoga: BB Gym runs classes at 10:00 and 18:30. Blue Lagoon in Klong Prao teaches from November to April with ฿300 drop-in classes. Bailan, the bay next door, is the island's calm corner of cafes and wellness. At the resort there is massage, a hammock in every sala and a pool to float in. Our slow living guide has a five-minute breathing practice to try at sunset.
9. Lonely Beach after dark
When the sun goes down, Lonely Beach turns up the music. Bars, live music and late-night food are within walking distance of Paradise Cottage: close enough to stroll home, far enough that the sea is what you hear when you fall asleep. More in Lonely Beach, honestly.
A slow five-day plan
- Day 1. Arrive, check in from 14:00, swim, sunset on the deck, dinner from the Thai kitchen.
- Day 2. Koh Rang snorkelling trip. Back in time for a massage and an early night.
- Day 3. Nothing. Pool, hammock, book, banana pancake. This is not a wasted day; it is the point.
- Day 4. Klong Plu waterfall in the morning, Bang Bao pier for lunch, the viewpoint on the way home.
- Day 5. East coast: Salak Khok kayaks and Salak Phet seafood, then your last Lonely Beach night.
Staying longer? Repeat day 3 as often as needed.
