Most people land in Bangkok, book the first flight to Phuket, and call it a Thailand trip. Completely fair, but they miss Koh Chang entirely, and that gap is hard to explain once you’ve actually been. Thailand’s second-largest island sits a few hours east of the capital, reachable by a short ferry from Trat, and it still hasn’t been smoothed out into a resort package.
The waterfalls are real jungle waterfalls. The fishing village at Bang Bao is still on stilts over actual water. The markets sell food for people who live there, not just people visiting. Things to do in Koh Chang cover a lot of ground: hikes, diving, beaches that don’t require elbow room, but what ties it all together is that the island still runs on its own rhythm, unbothered. Once you start looking into the actual things to do in Koh Chang, it becomes pretty obvious why the people who’ve been here once tend to come back.
Top Things to Do in Koh Chang You Shouldn’t Miss
1. Relax on White Sand Beach (Hat Sai Khao)
White Sand Beach stretches about 2 km and is the island’s longest. It gets busy from November to February, but early mornings are genuinely peaceful, just a handful of joggers and a few beach dogs. Sun loungers rent for around 50–100 THB, and the water is calm enough for swimming most of the year. It’s not the quietest spot on the island, but as a base, it’s hard to beat.
2. Visit Klong Plu Waterfall
Klong Plu is the most visited waterfall on the island and one of the classic Koh Chang activities. The falls drop about 25 meters inside Mu Ko Chang National Park. Entry is 200 THB for foreigners, and the walk in takes around 15 minutes from the car park. Worth knowing: the path gets genuinely muddy after rain and nobody at the ticket booth mentions it. Pack sandals you don’t mind getting dirty.
Here’s how Koh Chang’s three main waterfalls compare on crowd level and accessibility:
| Waterfall | Height | Entry Fee (THB) | Crowd Level |
| Klong Plu | 25m | 200 | High |
| Than Mayom | 10m | 200 | Medium |
| Klong Nonsi | 15m | Free | Low |
3. Explore Bang Bao Fishing Village
Bang Bao sits on wooden stilts at the island’s southern tip. Half of it is still a working fishing village; the other half is restaurants, dive shops, and souvenir stalls stretched along a long wooden pier. Go early if you can; by 11 AM it fills up. The views from the end of the pier over the bay are genuinely beautiful, and there are good seafood restaurants if you want to sit and eat with the water right beneath you.
What Is the Single Best Thing to Do in Koh Chang?
Most experienced travelers agree: a day trip by longtail boat to the surrounding islands.
Popular options include Ko Wai, Ko Mak, and Ko Kham, all within 1–2 hours of Bang Bao pier.
Ko Wai is the standout. Clear water, colorful coral, and far fewer crowds than Koh Chang itself.
Day trips run 1,200–2,500 THB and typically include snorkeling stops and a simple beach lunch.
It’s the kind of place where you think: ‘okay, this is why people actually come to Thailand.
4. Snorkeling and Diving Near Koh Chang
Koh Chang isn’t the Similan Islands, but the marine life is genuinely worth it. Dive sites like Hin Luk Bat and the HTMS Chang wreck, a decommissioned Thai navy vessel sunk in 2012, are popular with beginners and intermediate divers alike. A two-tank trip typically costs 2,500–3,500 THB including equipment.
According to the Thailand Department of Marine and Coastal Resources, Mu Ko Chang National Park covers 650 km² and protects some of the most intact coral reefs in the Eastern Gulf of Thailand. That matters when you’re deciding whether the dive is worth it; it usually is.
A quick look at typical water activity costs to help you plan your Koh Chang budget:
| Activity | Duration | Average Cost (THB) |
| Snorkeling day trip | Full day | 1,200–1,800 |
| 2-tank dive trip | Half day | 2,500–3,500 |
| Kayak rental | Per hour | 150–300 |
| Longtail to Ko Wai | Full day | 2,000–2,500 |
5. Hike in Koh Chang National Park
The national park covers roughly 70% of the island. Trail options range from flat coastal walks to steeper jungle routes. The Khlong Phrao to Than Mayom trail takes 3–4 hours return and passes through thick forest, hornbills, monitor lizards, and the occasional macaque. First-timers should go with a guide. Some paths aren’t well-marked, and getting turned around in Thai jungle is genuinely not fun.
6. Rent a Scooter and Explore
Renting a scooter, around 200–300 THB per day, is honestly the best way to see Koh Chang. The main road hugs the west coast and connects all the major beaches. Heading south toward Lonely Beach and Bang Bao takes about 40 minutes and cuts through forested hills that feel surprisingly remote. Watch out for steep, sharp bends between Kai Bae and Lonely Beach, especially if it’s been raining.
Is Koh Chang Good for Families?
Yes, especially the northern beaches like Hat Sai Khao and Khlong Phrao.
Both have calm, shallow water and plenty of beachside restaurants with shaded seating.
There are ethical elephant sanctuaries on the island. BEES Sanctuary and Koh Chang Elephant Sanctuary both have solid reputations for responsible, no-rides practices.
Families typically find 5–7 days ideal: enough time for beach days, a waterfall visit, and a boat trip.

7. Night Markets and Street Food
The Klong Son night market runs on weekends and is one of the most local-feeling spots on the island. Grilled seafood, pad thai, and mango sticky rice- most dishes come in under 60–100 THB. The White Sand Beach night market is more tourist-oriented but still enjoyable for a post-dinner wander. Either way, eating at the markets is one of those Koh Chang activities that costs almost nothing and stays with you.
Thailand’s night market and street food sector generates over $17 billion USD annually according to Euromonitor International, making it one of the country’s most significant informal economic ecosystems. Night markets on islands like Koh Chang are central to that.
8. Sunset Boat Trip
Most tour desks along White Sand Beach offer 2–3 hour sunset cruises for around 500–800 THB, usually including drinks. It’s a tourist staple, yes, but genuinely enjoyable. The light on the water around 5:30–6 PM on the western coast is the kind of thing you end up photographing way too many times. Smaller groups are more relaxed; ask the operator how many people will be on board before booking.
9. Kayaking the Coastline
Some of the most underrated Koh Chang activities involve nothing more than paddling slowly along the coast near Khlong Phrao or Kai Bae. You can drift into mangrove channels, spot kingfishers, and set your own pace. Most guesthouses along the beach rent kayaks by the hour, typically 150–300 THB. No booking needed.

Minimum 3 days, enough for beach time, one waterfall, and a local meal or two.
4–5 days is the sweet spot for most travelers: adds island hopping and a dive or snorkel trip.

Frequently Asked Questions
Is Koh Chang safe for solo travelers?
Yes. The main beaches have plenty of guesthouses, and the island has a relaxed, low-key vibe. Standard precautions apply: don’t rent a scooter without experience, keep valuables secured at the beach, and avoid isolated areas at night.
How do I get to Koh Chang from Bangkok?
Take a bus or minivan to Trat (around 5 hours), then a 30-minute ferry from Ao Thammachat or Centerpoint Pier. Total travel time is roughly 6 hours. Several companies run direct minivan-and-ferry packages from Bangkok’s Ekkamai or Mo Chit terminals.
What is the best beach in Koh Chang?
Hat Sai Khao (White Sand Beach) for convenience and atmosphere. Lonely Beach for a budget backpacker vibe. Kai Bae Beach if you want something quieter with good local restaurants and calm water.
Is Koh Chang worth visiting in 2025?
Absolutely. It’s less developed than Phuket or Koh Samui, the food is cheaper and more local, and the combination of beaches, jungle, and water activities is genuinely hard to find in one place. If you want a Thailand island that still feels a bit real, Koh Chang is it.
Can you swim in Koh Chang year-round?
West coast beaches are generally safe for swimming from November to April. During the monsoon season (May to October), stronger currents and waves make swimming riskier, especially at exposed beaches like Lonely Beach.
