TranslateOverview
Ko Chang is Thailand's third-largest island, located in Trat Province in the far eastern Gulf of Thailand, close to the Cambodian border. Despite its size, it has retained a more forested, rugged character than heavily developed islands such as Ko Samui or Phuket. The interior is dominated by Mu Ko Chang National Park, a protected area of steep, jungle-covered hills that drop sharply toward coastal villages and beaches.
The western coast holds the island's most visited beaches — Hat Sai Khao (White Sand Beach), Hat Kai Mook, Lonely Beach, and Bang Bao — each with a different atmosphere. The eastern coast is quieter and less developed, with fishing villages and mangrove channels. This contrast gives Ko Chang an unusual range for a single island: lively beach bars on the west, near-silence on the east.
Because Ko Chang sits within a national park, large-scale resort construction is theoretically limited, though development pressure has grown noticeably in recent years. Travelers seeking an uncrowded experience should note that Hat Sai Khao in particular can feel busy during the high season peak (December–February).
Before You Go
Visas
Ko Chang is part of Thailand, so standard Thai entry requirements apply. Visa rules depend on your nationality and can change. Check TravelerPulse's Visas section and the official Thai immigration authority website for current requirements before booking.
Health
- Mosquito-borne illnesses, including dengue fever, are present; use repellent and wear long sleeves at dawn and dusk.
- The island has a small hospital and several clinics, but for serious medical issues you will need to reach the mainland (Trat or Bangkok). Travel insurance with medical evacuation cover is strongly recommended.
- Tap water is not reliably safe to drink; use bottled or filtered water.
What to pack
- Light, breathable clothing; a rain layer even in dry season (brief showers occur)
- Reef-safe sunscreen — coral protection matters and some beaches enforce it
- Insect repellent
- A small amount of cash; ATMs exist on the island but can run out during busy periods
Getting There
Ko Chang is reached by ferry from the Trat Province mainland, most commonly from the piers at Ao Thammachat or Laem Ngop (verify which pier your ferry uses, as this changes by operator and season). The ferry crossing takes roughly 30–45 minutes depending on the vessel and departure point.
The nearest domestic airport is Trat Airport, which receives limited flights, primarily from Bangkok. Don Mueang (DMK) and Suvarnabhumi (BKK) airports in Bangkok are the main international gateways. From Bangkok, travelers typically reach the island by bus or minivan to the pier, or by flying into Trat. Bus and minivan services run from Bangkok's Eastern Bus Terminal (Ekkamai) and other hubs; journey times to the pier are approximately five to six hours depending on traffic and route. Verify current schedules with operators before travel.
Ferry frequency drops significantly during the low season (May–October), and some crossings may be suspended in rough weather. Always confirm sailings locally if traveling during or near the monsoon period.
Getting Around
The main road runs along the western coast of the island and connects most beaches and villages. Songthaews — covered pickup trucks that act as shared taxis — are the standard mode of local transport and run along this road. Negotiate fares before boarding; prices vary by distance and time of day.
Motorbike rental is widely available and is a common way to explore at your own pace. Roads in the interior and on the east coast can be steep and winding; riders without experience on mountainous roads should exercise caution. Helmets are legally required and should always be worn regardless of enforcement. Scooter accidents are one of the most common causes of traveler injury on the island.
Longtail boats can be hired to reach more remote beaches, the coral islands nearby (such as Ko Wai and Ko Kood), and for snorkeling trips. Kayak rental is also available at several beaches.
Where to Stay
Accommodation on Ko Chang ranges from basic fan-room bungalows to mid-range beach resorts. The island does not currently have a significant luxury resort market comparable to Phuket or Koh Samui, though some well-appointed properties exist on the west coast. Verify current availability and pricing on booking platforms, as the accommodation landscape changes between seasons.
Hat Sai Khao offers the widest choice and is convenient for those wanting restaurants, shops, and nightlife within walking distance. Lonely Beach suits budget travelers and those wanting a quieter, younger atmosphere. Bang Bao is a good choice if diving or island-hopping is the main agenda. The east coast villages have very limited accommodation but suit travelers who genuinely want to avoid the tourist circuit.
Book well ahead for the peak weeks around Christmas and New Year, when the island is noticeably busier and rooms sell out. During low season (May–October), many properties close entirely or operate on reduced hours; always confirm a property is open before arriving.
Things to See & Do
Beaches
- Hat Sai Khao (White Sand Beach) — The longest and most developed beach; suits those who want facilities, restaurants, and nightlife close by.
- Lonely Beach (Hat Tha Nam) — Historically popular with backpackers; a more laid-back vibe with beach bars.
- Bang Bao — A stilted fishing village converted into a strip of guesthouses, seafood restaurants, and dive shops at the island's southwestern tip; a good base for boat trips.
- East coast — Far quieter; accessible by road or boat; suited for travelers avoiding crowds.
Mu Ko Chang National Park
The national park covers most of the island's interior and includes several waterfalls, most notably Klong Plu Waterfall in the north and Than Mayom on the east coast. The park charges an admission fee (verify the current amount locally or on the national park authority's website). Jungle hiking is possible but trails can be unmarked; a local guide is advisable for longer routes.
Diving and Snorkeling
The waters around Ko Chang and the nearby smaller islands contain coral reefs with moderate diversity. Visibility and conditions are best November through April. Several dive operators are based in Bang Bao; verify certifications and safety standards before booking.
Elephant Sanctuaries
A number of elephant camps operate on Ko Chang. Standards vary widely. Look for operations that follow ethical practices — no riding, no performances — and do independent research on specific operators before visiting.
Food & Drink
Seafood is the centerpiece of eating on Ko Chang. Fresh fish, prawns, crab, and squid are grilled, stir-fried, or served in Thai-style curries at restaurants across the island. Bang Bao's restaurant pier is a well-known spot for fresh seafood meals with water views, though prices there reflect its popularity.
Beyond seafood, standard Thai dishes — pad Thai, green and red curries, som tam (papaya salad), and kao man gai (chicken rice) — are available throughout the island at both dedicated Thai restaurants and guesthouses. Hat Sai Khao has the greatest concentration of international options, including Western and pan-Asian food, aimed at long-stay tourists.
Local market stalls and street-food vendors in the inland villages and along the main road offer the most affordable and often the most authentic meals. The Saturday and Sunday evening markets (verify current days locally) can be a good place to eat cheaply and pick up local produce. As on much of the Thai coast, alcohol is readily available; bars on Hat Sai Khao and Lonely Beach operate into the early hours during high season.
Practical Information
Money
ATMs are available on the island, mainly along the Hat Sai Khao stretch and in the main village areas. International card surcharges apply; carry sufficient cash for remote beaches and smaller establishments, which may not accept cards.
Connectivity
Mobile data (via Thai SIM cards, available at the airport or convenience stores on the mainland) works reasonably well on the west coast. Coverage can be patchy in the interior and on the east coast. Wi-Fi is available at most guesthouses and restaurants in the tourist zones.
Emergency contacts
- Thai general emergency number: 191 (police), 1669 (medical emergency) — verify these are current before travel.
- The island has a small government hospital; for serious emergencies, evacuation to Trat or Bangkok may be necessary.
National park fees
Entering Mu Ko Chang National Park incurs a fee for foreign visitors. Verify the current fee with the Department of National Parks, Wildlife and Plant Conservation (DNP) before visiting.
Safety
Ko Chang is considered a relatively safe destination for travelers. The most common risks are road accidents (motorbike), sea conditions, and petty theft. Avoid riding motorbikes if inexperienced, especially on steep inland roads in wet conditions.
Ocean currents and waves during the monsoon season (May–October) can be dangerous; red flags on beaches indicate unsafe swimming. Even in dry season, riptides occur at some beaches. Heed local warning signs and ask guesthouse staff about current conditions.
Jellyfish, including box jellyfish, have been reported in Thai Gulf waters, particularly in warmer months. Water shoes and awareness are advised. Seek medical attention promptly for any serious sting.
As with anywhere, keep valuables secured, avoid displaying expensive items openly, and use a small padlock on guesthouse bungalow doors where appropriate.
Local Culture & Etiquette
Ko Chang has a mix of long-established Thai fishing communities and newer tourist infrastructure. The inland and east-coast villages maintain a quieter, more traditional character; travelers venturing away from the west-coast tourist strip are guests in working communities and should dress and behave respectfully.
Buddhist temples (wats) are present on the island. Standard temple etiquette applies: remove shoes before entering, dress modestly (shoulders and knees covered), and speak quietly. The national park status of much of the island reflects a broader cultural and legal framework around environmental stewardship — do not remove coral, shells, or plants.
A historical note of particular interest: the Battle of Ko Chang took place in January 1941, a naval engagement between French and Thai forces during a border dispute. There is a small memorial on the east coast at Than Mayom that some visitors find worth seeking out.
