Bangkok's closest proper island escape, with powder-white sand, a protected national park and a string of small, easy-going bays.
Why Koh Samet? Bangkok's closest proper island escape, with powder-white sand, a protected national park and a string of small, easy-going bays.
Koh Samet is the nearest real island getaway from Bangkok: a small, forested national park fringed with fine, bright-white sand and a necklace of little bays down its eastern shore. Thai weekenders pack the northern beaches, but walk a little further south and the pace drops to hammocks, rocky coves and quiet snorkelling. It suits couples, friends and anyone short on time who wants a proper beach without flying.
Two or three nights is ideal - long enough to try a couple of bays, take a boat to the outer islets and watch at least one sunset from the west coast.

Buses and minivans run from Bangkok's Ekkamai terminal and other pick-up points to Ban Phe pier in Rayong, taking about 3-4 hours depending on traffic. From there, slow ferries reach Na Dan pier in roughly 30-40 minutes, while speedboats take about 15 minutes and can drop you at your own beach. Foreigners pay a national park entrance fee on arrival, currently around 200 THB. On the island, green songthaews shuttle between the pier and the bays, and many people simply walk or rent a scooter or ATV for the rough inland tracks.
The north-east is the busiest stretch: Hat Sai Kaew has the most hotels and the whitest sand, while Ao Hin Khok and Ao Phai are smaller and more sociable. Mid-island, Ao Wong Deuan is a sheltered, family-friendly bay with calm water and a long line of restaurants. Further south, Ao Thian, Ao Wai and Ao Kiu feel more secluded and rustic. On the west side, Ao Prao is quiet and upmarket, best for couples who want sunsets over the Gulf. Weekends and Thai holidays get very busy, so book ahead or come midweek.
Samet's own reefs are modest, so most people join a half-day or full-day longtail trip to the surrounding islets. Koh Kudee has a lovely small beach and clear shallows, Koh Talu is known for its fish and rocky reefs, and many tours add a stop at Koh Mun Nai. Back on land, the coastal path links almost every eastern bay, climbing over headlands with sea views, and the southern tip at Ao Kiu is one of the few spots where you can cross from the east coast to the west in minutes.
Evenings revolve around the sand. Restaurants on Hat Sai Kaew and Ao Wong Deuan set out tables at the water's edge and display the day's fish, squid and prawns for grilling. Ao Phai is the place for fire shows, cocktail buckets and bean bags under the stars, though the scene stays relaxed compared with Phuket or Koh Phangan. For a quieter night, head to the southern coves, where a handful of simple bars and bungalow restaurants close early and the only soundtrack is the sea.
Samet sits in one of Thailand's drier corners, which makes it a reasonable year-round option. The best weather runs from November to April, with calm seas and clear skies; March and April are hot. From May to October showers and occasional rougher seas can affect speedboats and snorkelling trips, but rain often comes in short bursts and prices drop. Avoid long weekends and Songkran if you want space, and remember that the island is a national park, so take your rubbish with you and keep noise down on the quieter southern bays.
