Ko Samed
Although not Bangkok's nearest island escape—islands like Ko Sichang and Ko Larn are significantly closer—Ko Samed is…
introduction
Overview
Ko Samed sits 220 kilometres southeast of Bangkok in the Gulf of Thailand. You reach it by a 30-minute speedboat or 45-minute wooden ferry from Ban Phe Pier in Rayong. The eastern shore delivers white sand beaches linked by pick-up truck taxis, while the steep west coast turns toward quiet sunsets. Because most of the island belongs to a national park, you pay an arrival fee and trade highway traffic for brick tracks and beachfront seafood.
National park entry fee
Foreign visitors pay a 200 THB entry fee upon arrival at Nadan Pier. Keep your paper ticket because park rangers inspect receipts at southern beach checkpoints.
Driest microclimate in the gulf
Ko Samed receives significantly less rainfall than mainland Rayong. Even during the rainy season, storms pass quickly across the island's narrow ridge.
Mainland ferry hub
Ferries leave Ban Phe Pier hourly for Nadan Pier until 17:00. Private speedboats operate past dark but charge higher fees for night runs.

Grilled squid, papaya salad, and beachside charcoal fires
Dining on Ko Samed revolves around dinner tables set directly on the sand. As daylight fades, vendors roll out low wooden tables and matting along Sai Kaew and Ao Phai. Rayong province is famous for fish sauce and dried seafood, so local cooks grill squid and whole sea bass over hot coal fires. Expect central Thai heat in local papaya salads rather than toned-down resort cooking.
Fresh grilled seafood served with seafood dip right on the beach.
Takeaway · CC BY-SA 3.0- Rayong nam pla dip
Local seafood comes with green chili dip made from Rayong fish sauce, lime, and raw garlic.
- Sand table setup starts at 17:30
Beach restaurants begin placing cushions and wooden tables on the wet tide line before sunset.
- Village main street cash preference
Small noodle shops near Nadan Pier prefer cash payments, while resort restaurants take cards.
history
A short history
Ko Samed gets its name from the samet trees (paperbark trees) that grow across the interior. Royal poet Sunthorn Phu placed part of his 19th-century epic poem Phra Aphai Mani on the island, calling it Ko Kaeo Phisadan or Magic Crystal Island. For generations it remained a quiet fishing outpost until Bangkok weekenders began making the journey in the 1970s. National park designation in 1981 restricted major concrete hotel construction on southern coves.

Poetic immortalisation
Sunthorn Phu sets scenes of his classic Thai epic poem Phra Aphai Mani on the island's shores.

where to stay
Where to stay
Choosing where to stay on Ko Samed comes down to your tolerance for evening noise versus your transport budget. Sai Kaew puts you steps from restaurants and nightlife, but music echoes along the sand until late. Southern coves like Ao Wong Duean offer quieter nights, but require green songthaew rides or boat transfers to move around.

transport
Getting around
No private rental cars operate on Ko Samed. Arrival wooden ferries and speedboats land at Nadan Pier on the northern tip. From there, green open-air pick-up trucks (songthaews) wait outside the pier control station to haul passengers south along the single spine road. You can also rent automatic motorbikes, though steep hills between southern coves demand cautious riding.
Songthaews operate on fixed fares per person to main beaches, posted on a board at Nadan Pier.
If traveling with a group, charter the whole pick-up truck to avoid waiting for it to fill up.
Unlit dirt offshoots and steep concrete gradients make evening scooter rides risky.
Rangers check park fee receipts when songthaews cross entry points into inner forest zones.
cost
What things cost

Standard entry fee paid in cash at Nadan Pier for foreign tourists (40 THB for Thai citizens).

practicalities
Good to know
- Reef-safe sunscreen mandatory

- Mainland car parking at Ban Phe
Covered parking lots near Ban Phe Pier charge around 50–100 THB per night for overnight driving trips.
- Bangkok weekend rush
Friday afternoons bring heavy traffic on local ferries as Bangkok residents travel down for short stays.
- Limited ATM access on southern bays

- Tide impacts walking between coves
High tide cuts off rocky paths connecting Sai Kaew, Ao Phai, and Ao Tubtim, requiring road detours.
