Koh Samet Travel Guide: The Closest Island Paradise to Bangkok
Koh Samet: Bangkok’s Weekend Island
Koh Samet sits 200 km southeast of Bangkok — close enough to reach in three hours by bus and ferry, which makes it the default weekend escape for Bangkok’s expats and middle class. It is a national park island, which keeps development limited and the beaches relatively clean. The water is calm — it faces the Gulf of Thailand, sheltered from the monsoon seasons that batter Phuket — and the pine trees that back many beaches give it a look unlike most of southern Thailand.
Koh Samet is not a place for multi-day diving or jungle trekking. It is a place for lying on the beach, eating good seafood, and letting Bangkok decompress out of your system over a long weekend.
Beaches
Hat Sai Kaew (Diamond Beach) is the main beach, with the finest white sand on the island. It is also the most crowded and has the most infrastructure — sunbeds, food stalls, beach bars, and fire-show entertainment in the evening. Most of the hotels and resorts on the east coast are clustered here and along the next few bays south.
Ao Hin Khok and Ao Phai are the next bays south, slightly quieter than Hat Sai Kaew with a good mix of bungalows and beach bars. These are popular with the Bangkok backpacker crowd.
Ao Phutsa (Ao Tubtim) and Ao Nuan are quieter still, with a more relaxed atmosphere and fewer sunbed vendors. Ao Nuan in particular has a loyal following among those who want simplicity — a handful of bungalows, a good beach bar, and not much else.
Ao Wai and Ao Kiu on the southern end require a longer walk or boat ride and are nearly empty. Ao Wai has some development; Ao Kiu Na Nai (the west-facing bay) catches the sunset and is beautiful in late afternoon.
Ao Wong Duan is the main beach on the middle of the east coast — quieter than Hat Sai Kaew with a direct ferry link from Ban Phe pier on the mainland.
Activities
Snorkeling is the main water activity — the reefs around the south of the island are in reasonable condition. Equipment can be rented at most beaches for 100–150 baht. There are some dive operators on the island, but the diving is limited compared to Koh Tao or Koh Chang — visibility is often reduced by runoff from the mainland.
The island has decent hiking trails connecting the beaches along the east coast. Walking from Na Dan Pier (the ferry landing) south to Hat Sai Kaew and then further down to Ao Phutsa takes about an hour. The trail to the south end of the island continues for another hour through jungle.
Sea kayaking is available from several beaches — the west coast at sunset is a popular paddle.
National Park Admission
Koh Samet is part of Khao Laem Ya – Mu Ko Samet National Park. The entry fee is 200 baht for foreigners, collected at the checkpoint just past Na Dan Pier. This is non-negotiable and applies to all visitors regardless of where they are staying. Keep your receipt as checks are sometimes done at beach entry points.
Practical Information
📍 Location on Google Maps
Getting there: Take a bus from Ekkamai (Eastern Bus Terminal) or Mo Chit to Ban Phe. Buses run approximately every hour, journey time 3 hours, 150 baht. From Ban Phe pier, take a ferry to Na Dan Pier on Koh Samet (30 minutes, 60 baht) or to Ao Wong Duan (1 hour). Ferries run from 07:00 to 17:00. An air-conditioned bus from Bangkok direct to Ban Phe pier departs from Ekkamai daily.
Getting around the island: Songthaews run from Na Dan Pier to the various beaches. Hat Sai Kaew is 10 baht, further beaches are 20–40 baht. Motorbike taxis are also available. The island is small enough to walk between nearby beaches.
When to visit: Koh Samet’s sheltered position means it receives less rain than western Thailand beaches during the main southwest monsoon (May–October). It is essentially a year-round destination, with the driest and calmest months from November to April.
Budget: Basic bungalows start around 500 baht. Resorts run from 1,500 to 5,000+ baht depending on beach location. Seafood restaurants range from 150 to 500 baht for a main dish. The island is slightly pricier than Pattaya but comparable to Koh Chang.
Combining with Pattaya and the Eastern Seaboard
Koh Samet, Pattaya, and the eastern seaboard make a natural circuit from Bangkok. Spend a night in Pattaya, take a morning bus to Ban Phe (2 hours from Pattaya), then two nights on Koh Samet before returning to Bangkok. The whole trip works in four days. Alternatively, pair Koh Samet with Koh Chang via a minibus and ferry connection through Trat (3 hours further east) for a proper island escape.
