Koh Chang doesn't try to be Phuket. It doesn't try to be Samui. It sits near the Cambodian border, covered in jungle, surrounded by a marine national park, and quietly offering some of the best experiences in Thailand to the travelers who bother to show up.
Here are the twelve things worth your time.
The best waterfall on the island — a three-tiered cascade dropping through jungle into a natural swimming pool at the base. The water's cold (a shock after the tropical heat), the rocks are covered in moss, and the setting feels like something from a nature documentary.
Entry: 200 THB (~$5.60) plus 40 THB national park fee. Get there before 10 AM to beat the tour groups. The swimming pool at the first tier is the main attraction, but a trail climbs to the upper tiers for better views.
Pro tip: Wear proper shoes, not flip-flops. The path is muddy and the rocks around the falls are slippery. I watched three people fall in flip-flops. Don't be the fourth.
A picturesque fishing village built entirely on stilts over the water at Koh Chang's southern tip. A wooden boardwalk runs the length of the village, passing seafood restaurants, dive shops, souvenir stalls, and a lighthouse at the end.
Lunch here is the move. A whole grilled barramundi with papaya salad and rice: 200-350 THB (~$5.60-9.80). Eat on the deck over the water and watch the dive boats come and go.
Bang Bao is also the departure point for boat trips to the outer islands — Koh Rang, Koh Kood, and Koh Mak.
The snorkeling off Koh Chang's beaches is mediocre. The real marine life is at Koh Rang — uninhabited islands 90 minutes south by speedboat. Day trips: 800-1,500 THB (~$22-42) including lunch, snorkeling gear, and 3-4 stops.
Expect: visibility up to 20 meters, healthy hard coral, parrotfish, angelfish, clownfish in anemones, and the occasional hawksbill turtle. The coral at Koh Rang is in genuinely good condition — protected as part of the marine park.
On the quieter east coast, Than Mayom is a three-tiered waterfall that was a favorite of Thai royalty — Kings Rama V, VI, and VII all visited, and their initials are carved into rocks at the base. Less dramatic than Klong Plu but more atmospheric.
Entry: 200 THB (~$5.60). The trail continues past the waterfall to a viewpoint with east coast panoramas. Allow 2-3 hours for the full walk.
Lonely Beach (Hat Tha Nam) is Koh Chang's backpacker hub — a small, slightly scruffy beach surrounded by cheap bungalows (300-800 THB / ~$8-22/night) and reggae bars. The beach itself is narrow and rocky in places, but the sunset from the bars is spectacular.
Order a Singha, sit on a beanbag, and watch the sky do things that feel illegal. The fire show starts around 9 PM at most of the beach bars. It's chaotic, slightly dangerous, and enormously fun.
The east coast mangrove forests at Salak Kok are navigable by kayak — paddle through tunnels of mangrove roots in water so clear you can see the bottom. Rental: 200-300 THB/hour (~$5.60-8.40). Best at high tide when you can penetrate deeper into the forest.
Wildlife: mudskippers, fiddler crabs, possibly a water monitor lizard (I saw two), and birds — egrets and kingfishers mostly.
White Sand Beach has the most restaurant options on the island. Skip the tourist menus and head for the Thai restaurants set back from the beach road — Kati Culinary does an excellent massaman curry (120 THB / ~$3.40), and the unnamed cart near the 7-Eleven makes the best pad thai I had on the island (50 THB / ~$1.40).
For seafood, the restaurants at the northern end of White Sand Beach have tanks where you pick your fish. Grilled sea bass for two: 300-500 THB (~$8.40-14).
Koh Chang ("Elephant Island") takes its name seriously. The Koh Chang Elephant Haven offers no-riding encounters — you feed, bathe, and walk with rescued elephants in a jungle setting. Half-day: 2,500 THB (~$70).
Important: avoid any operation that offers riding, painting, or performances. Ethical encounters let elephants behave naturally. If there's a chair on the elephant's back, walk away.
The coastal road from White Sand Beach to Bang Bao is one of the most scenic drives in Thailand — steep climbs through jungle, sudden ocean vistas, and switchbacks that require serious concentration. About 30km one way.
Rent a motorbike: 200-300 THB/day (~$5.60-8.40). Drive slow, especially on the hills between Kai Bae and Lonely Beach. Stop at the viewpoints — there are several unmarked pullouts with sweeping views of the coast and outer islands.
Koh Chang isn't Thailand's premier dive destination, but it's surprisingly good. Dive shops in Bang Bao and White Sand Beach offer trips to Koh Rang, Hin Luk Bat (a submerged pinnacle with barracuda schools), and the HTMS Chang wreck (a former navy vessel deliberately sunk for diving).
Two-dive day trip: 2,500-3,500 THB ($70-98). PADI Open Water course: 10,000-12,000 THB ($280-336). Cheaper than Koh Tao but with fewer dive sites.
A small, uncrowded temple on the east coast with a giant seated Buddha and views across Salak Phet Bay. No entrance fee. No tourists. Just a quiet temple in the trees with a monk or two sweeping the courtyard. It's the kind of Thai temple experience that's impossible to find on the more developed islands.
If Koh Chang is Thailand's underrated island, Koh Kood is the secret behind the secret. Boats from Bang Bao run to Koh Kood in about 45 minutes (400-600 THB / ~$11-17 one-way). The beaches — particularly Klong Chao Beach — are among the best in Thailand. Clear water, white sand, and almost nobody there.
Koh Kood also has Klong Chao Waterfall — a jungle cascade you can swim in with actual fish in the pool. Do a day trip, or stay overnight and wonder why you booked any other island.
Pro tip: Koh Mak, between Chang and Kood, is even quieter. A bicycle-sized island with no cars and beaches that look too perfect to be real. The ultimate "I found somewhere nobody knows about" Thai island. For now.
