Koh Chang (‘Elephant Island’) sits in Trat province on Thailand's eastern Gulf coast, close to the Cambodian border, and is one of the country's largest islands after Phuket. Most of its mountainous interior is protected as Mu Ko Chang National Park, so development is concentrated in a belt of beach towns along the west coast — White Sand Beach, Klong Prao, Kai Bae, Lonely Beach and the fishing village of Bang Bao. It suits people who want real jungle-and-beach island life within a day's travel of Bangkok, with the trade-off of thinner healthcare, a very limited condo market and a genuine May-to-October low season.
White Sand Beach is the main tourist strip with the widest choice of restaurants and everyday amenities. Klong Prao, the island's longest beach, leans upscale and family-friendly. Kai Bae sits in the middle with a genuine mix of budgets and the island's best-known sunset. Lonely Beach is the budget backpacker and nightlife hub. Bang Bao is a stilted fishing village and the main jump-off point for boat trips. Klong Son, near the northern ferry piers, is the quieter, more local arrival point.
The nearest airport is Trat (Bangkok Airways), about a 20-minute drive from the ferry piers, or it's roughly a 5-6 hour road trip from Bangkok direct to the Laem Ngop-area piers. Car ferries to Koh Chang run daily from about 06:00 to 19:30, with the last crossing around 18:30. On the island itself there's no real public transport network — most residents rent a scooter or car, and songthaews (shared pickup taxis) cover the main beach road.
A large majority of Koh Chang's interior falls inside Mu Ko Chang National Park, which limits development to a coastal strip and keeps the island genuinely forested compared with Phuket or Koh Samui. This is good for the island's character but a real constraint for property: buildable, titled land is scarcer and concentrated along the west coast, so confirm land title and any protected-area boundary carefully before renting or investing near the treeline.
Koh Chang's long-stay housing is almost entirely bungalows, houses and villas rather than condos — genuine condominium stock on the island is very limited. Typical monthly rent for a bungalow or house runs from roughly THB 10,000 for a small, basic place up to THB 30,000-70,000+ for a larger or more luxurious villa. Electricity and water are usually billed separately from rent, with electricity priced around THB 5-7 per kWh — budget for it on top of the quoted rent.
Koh Chang has an on-island branch of Bangkok Hospital that's open 24 hours with emergency facilities, though it's expensive without insurance (around THB 4,000 just to see a doctor). There's also a smaller government hospital for routine and lower-cost care. Anything more serious typically means a transfer to Trat town on the mainland or on to Bangkok, so comprehensive health insurance with real evacuation cover matters more here than in cities with bigger private hospitals.
Unlike several of Thailand's smaller resort islands, Koh Chang has its own full-time Thai Immigration Office on the island (open since 2024), so most long-stay residents can handle 90-day reporting, extensions of stay and other routine filings without a Trat mainland trip — a genuine practical advantage over islands that route everything through a provincial capital.
The same national visa options apply on Koh Chang as anywhere in Thailand — the DTV for digital nomads, the LTR for high earners and retirees, retirement visas for over-50s, the Thailand Elite/Privilege membership, and marriage and education visas — each with its own income, insurance and reporting requirements, filed at the island's own immigration office.
Beyond the beach: Mu Ko Chang National Park's jungle trails and waterfalls (Klong Plu and Than Mayom among the best-known), the stilted seafood village at Bang Bao, and boat trips and diving/snorkelling day trips to the smaller islands nearby such as Koh Wai and Koh Kood. Kai Bae's headland is the island's best-regarded sunset spot.
Koh Chang follows the same May-to-October southwest monsoon as the rest of the Gulf coast, and a real low season through that period when some restaurants, bars and dive operators close or reduce hours. Day-to-day risks are the usual island ones — scooter accidents on hilly, sometimes poorly lit roads, rip currents and jellyfish in the sea, and the practical distance to advanced medical care noted above.
White Sand Beach carries the widest restaurant choice, Klong Prao and Kai Bae run genuine Thai seafood alongside a growing international mix, Lonely Beach keeps things cheap and backpacker-friendly, and Bang Bao's stilted fishing-village pier is the island's signature seafood-over-water experience.
Lonely Beach is Koh Chang's backpacker and nightlife hub — reggae bars, fire shows and cheap buckets along the Soi 1 strip. White Sand Beach's evening night market and bar strip add a calmer option, with the island's only nightclub, Babylon, tucked into the Little Pattaya bar zone at its southern end. Kai Bae's bars are the pick for sunset drinks. Away from these three areas, evenings on Koh Chang are quiet, especially in the May–October low season.
Koh Chang has no on-island English-medium or international school — the real routes families use are homeschooling and accredited online curricula, ordinary Thai government schools (Thai-language only), or mainland alternatives: St. Andrews International School, Green Valley near Rayong (day school, roughly 2.5-3 hours away) or Regents International School Pattaya (day and boarding, roughly 4 hours away), with Bangkok's much larger international-school market further still.
Koh Chang's banking scene has thinned since the pandemic — Krung Thai Bank in White Sand Beach is the main surviving full-service branch, with GSB (Klong Prao) and BAAC (Klong Son) running currency-exchange counters. Many long-stayers open their first account in Trat town, then bank day-to-day on the island via ATM and PromptPay.
Koh Chang follows the same national rules as the rest of Thailand: foreigners may own a condo unit freehold within a building's 49% quota, but genuine registered condo stock on the island is scarce. Most long-stay housing here is houses, bungalows and villas held on a registered leasehold (up to 30 years, via the Trat Provincial Land Office) or through a Thai company structure — each with real legal limits worth understanding before you commit.
Fibre and mobile coverage on Koh Chang is solid along the main west-coast beach strip — White Sand Beach, Klong Prao, Kai Bae and Lonely Beach — but thins out fast once you move off the ring road into the national park interior or the quieter south around Bang Bao and Salakphet. AIS, True and 3BB all run fibre to the developed areas, AIS carries the strongest mobile signal overall, and every SIM — physical or eSIM — must be registered to a passport under Thailand's 2026 NBTC rules.
Koh Chang works for retirees who want real jungle-and-beach island scale, a 24/7 private hospital on White Sand Beach and its own full-time immigration office (since 2024), at prices below Phuket or Koh Samui. White Sand Beach, Klong Prao, Kai Bae and Klong Son near the ferry piers are the practical bases; the Lonely Beach nightlife strip and Bang Bao, with almost no long-term rental stock, make both poor fits for most retirees.
Four genuinely active, owner-taught Thai cooking schools serve the island: Napalai Thai Cuisine School (White Sand Beach, top Tripadvisor rating, three sessions daily), Ka-Ti Culinary (Klong Prao, taught inside a working restaurant kitchen), Koh Chang Thai Cooking School (two daily sessions) and Blue Lagoon (Klong Prao, themed classes — confirm current status). Prices run roughly THB 1,200-2,000 per person.
