Koh Chang is what Koh Samui was in 2005, Thailand's second-biggest island, four hours from Bangkok, and still mostly jungle.
editorial
The case & the friction.
ExpatWhy editorial
A fan-bungalow on Lonely Beach runs 600 THB/night ($17), and a month at a beachfront resort on Klong Prao with AC and a pool negotiates to 18,000 THB ($510) in low season. Pad krapow at the Klong Son market is 60 THB ($1.70). White Sand Beach is the package-tour strip and 30% pricier, Lonely Beach is the backpacker pocket, Bang Bao the fishing-village south end with the best seafood at 250 THB/kg for prawns.
Friction is May through October, the southwest monsoon dumps 300mm/month, the speedboat from Laem Ngop runs reduced schedules, and Lonely Beach genuinely empties out. Many bungalow operators close June to September. November to February is dry and 28°C; March–April is hot and hazy from mainland burn season. The Khao Salak Phet waterfall only flows properly July to November.
Thailand's five-year Destination Thailand Visa (DTV) launched 2024 grants 180-day stays per entry with 500,000 THB proof of funds, built for remote workers exactly here. The ferry from Trat takes 30 minutes and runs 80 THB. Roads on the island are steep and motorbike accidents account for most tourist injuries, wear shoes, not flip-flops. English is limited outside resort strips.

National-average international-school primary tuition, aggregated from published 2025/26 fee schedules across the country's international schools. Country baseline, not anchored to schools in this specific city; the real figure for a given school varies with tier, location and grade. Preschool = full-day international preschool, annual. Secondary is an estimate, modelled as a published uplift over primary (low +20%, typical +30%, high +40%), since secondary tuition rises with grade; it is not a separately sourced figure.
Tuition only. Excludes one-off enrolment/capital levies, school bus, lunch, uniforms and exam fees, which add materially at most schools.
