About Koh Samet
Koh Samet is a small island in Rayong province, part of Khao Laem Ya–Mu Ko Samet National Park, about 200 km from Bangkok and reachable in 3 hours including the ferry from Ban Phe. The 6.5 sq km island has over a dozen beaches, from bustling Hat Sai Kaew with beach bars and fire shows to quiet Ao Wai and Ao Karang. Ao Prao on the western shore offers upscale resorts and sunsets. National park status keeps beaches clean with a 200 THB foreigner entry fee. Monthly costs of $600-1,200 reflect imported goods and limited housing. Internet averages 30 Mbps via 4G, suitable for part-time remote work. The permanent population of roughly 1,000 concentrates near Na Dan pier, making this a seasonal haven for beach-loving remote workers.

Getting Around Koh Samet
Speedboats and ferries depart from Ban Phe pier (Rayong province) every 30 minutes (30 min, 100-200 THB). Ban Phe is 3 hours from Bangkok by bus (200 THB). On the island, songthaews run between beaches (50-100 THB per trip). The island is compact enough to walk between some beaches. No cars or motorbikes are allowed on most of the island, though some resorts use golf carts. The last ferry back to the mainland departs around 5 PM.
Island Beaches and National Park
Koh Samet is part of Khao Laem Ya National Park, which keeps development controlled despite its proximity to Bangkok. Hat Sai Kaew (Diamond Beach) is the longest and busiest beach with beach bars and water sports. Ao Phai and Tub Tim Beach offer quieter alternatives. The east coast beaches like Ao Wai and Ao Kiu Na Nok are serene and uncrowded. Snorkeling is decent at Ao Phrao on the west coast. The island famously inspired Thai poet Sunthorn Phu's epic 'Phra Aphai Manee.'
Practical Living
Internet: AIS 4G at 40-60 Mbps, decent coverage on most beaches. Healthcare: Small clinic at Na Dan village; Rayong Hospital on the mainland (45 min by boat + car) for serious issues. Shopping: Minimarts and small shops at Na Dan village; limited fresh food options. Water is scarce during dry season. National Park fees apply (200 THB for foreigners entry). Long-term stays are uncommon but possible, especially during the low season (May-October) when resorts offer significant discounts.
Pros and Cons of Living in Koh Samet
Advantages
- Close to Bangkok
Just 3 hours from Bangkok, making it the closest proper island escape for weekend trips.
- Beautiful white sand beaches
National park protection keeps the beaches remarkably pristine with fine white sand.
- Compact and walkable
The small island size means everything is within walking distance or a short taxi ride.
- Laid-back island atmosphere
A genuinely relaxed vibe with no high-rise buildings, limited nightlife beyond beach bars, and a slow pace.
Considerations
- Expensive for Thailand
Island premiums on food, accommodation, and services make it 2-3x more costly than mainland towns.
- Limited internet reliability
30 Mbps average with frequent slowdowns during peak season, unsuitable for bandwidth-heavy remote work.
- Seasonal weather risk
The May-October monsoon brings heavy rain, rough seas that cancel ferries, and many businesses close entirely.
