Ko Samet travel guide
White-sand bays, seafood barbecues and fire shows near Bangkok
Ko Samet is a small national park island off Rayong, a few hours from Bangkok by road and boat. Go from November to April for dry weather, and midweek if you can, because weekends are packed. Two or three nights is the right length. Prices are low, and a 30-day visa exemption covers many nationalities.
Ko Samet is the nearest proper beach island to Bangkok: a 6.8 km sliver of land off Rayong, reached by road to Ban Phe pier and then a short boat ride. Bangkok families and students pour over every weekend. Almost the whole island lies inside a national park, so you pay an entry fee on arrival.
Nearly all the beaches line the east coast. Hat Sai Kaew, a kilometre of white sand near the pier, is the busiest, packed with deckchairs, jet skis and banana boats. A rocky point with a mermaid statue separates it from Ao Hin Khok. Ao Phai, next along, has the bars with nightly fire shows. Ao Phutsa and Ao Thapthim are calmer.
Head south for space. Ao Wong Deuan is a busier crescent with a pier of its own, but past it the bays get smaller: Ao Cho, Ao Thian (Candlelight Beach) and Ao Wai, each with a handful of bungalows. Over on the west coast, sunset watchers gather at Ao Prao.
The island has just one main road, part concrete and part rutted dirt. Songthaews shuttle between beaches with fares posted at each stop. Hiring a scooter gives more freedom, though the tracks are rough. Walking the paths between the northern bays is often quicker.
Bring cash from the mainland. ATMs on the island have come and gone, and in October 2025 the only one reported stood opposite the Hat Sai Kaew tourist service centre. Seafood barbecues set up on the sand every night; tables at Ao Phai and Hat Sai Kaew are the liveliest, but look past the restaurants that tour groups are steered to. Mornings are the best time on the beach, before the day trippers land.

Getting there
Road to Ban Phe, then the boat
Every route funnels through Ban Phe, the pier town on the eastern outskirts of Rayong, roughly 220 km from Bangkok. From there slow boats cross to Na Dan, the island's port, in 30 to 45 minutes, and speedboats run straight to several beaches. Drivers from Bangkok follow Sukhumvit Road (Highway 3) down the coast; turning onto Highway 36 at Bang Lamung, before Pattaya, cuts about 45 km at the cost of the sea views. Allow about two and a half hours to the pier.
- Bus from Ekamai
- About 3.5 hours from Bangkok's Eastern Bus Terminal, ending opposite the ferry piers
- Bus from Mo Chit
- Runs only to Rayong; a songthaew covers the last stretch to Ban Phe
- From Suvarnabhumi
- Direct first-class buses to Rayong, then a songthaew to the pier
- Taxi
- Possible from Bangkok or Rayong; say Ban Phe, not Rayong, and settle an off-meter price and expressway tolls before you leave
- Boat
- Slow ferry to Na Dan in 30 to 45 minutes, or a speedboat to the beach you are staying on
- Park rangers collect the national park entry fee as you arrive, and Thailand residents with proof can ask for the Thai rate.
- Bangkok traffic on Friday afternoons is slow; leave in the morning or travel midweek.
Where to stay
North-end bars or south-end coves
On an island this narrow, your bay decides the trip more than any hotel does. Rooms are mostly bungalows run by the restaurant on the same stretch of sand, and the further south you sleep, the fewer neighbours and the longer the bumpy ride back to Na Dan.
- Hat Sai Kaew
- A short walk from the ferry, with the most shops; expect jet-ski engines by day and full rooms every weekend
- Ao Hin Khok and Ao Phai
- Budget bungalows for a younger crowd, a few steps from the fire shows and beach bars; music carries late
- Ao Phutsa and Ao Thapthim
- Mid-range bungalows for couples who want quiet nights yet can still stroll north for dinner
- Ao Wong Deuan
- A lively bay with its own speedboat pier, good for families who want restaurants on hand
- Ao Prao
- The sunset coast, with a few pricier resorts and little else nearby, so you depend on their kitchens
- On Friday and Saturday nights walk-in rooms on the northern bays can run out; reserve before you leave Bangkok.
- Booking a southern cove? Take a speedboat from Ban Phe straight to that beach and skip the songthaew from Na Dan.
Getting around
Songthaews, scooters, footpaths
One road runs down the spine of the island, concrete in stretches and a bumpy dirt track elsewhere. In the north the bays are a few minutes apart, joined by paths over the rocky points, so you rarely need a ride. Wheels earn their keep further south, where the coves are smaller and the forest thicker. ATV hire is no longer offered.
- Songthaews
- Open pickups with two benches; share and pay per person, or charter one. Boards at each beach drop-off list the fares to every other beach
- Scooter hire
- By the hour or the day from shops near the main beaches; dirt sections get rough after rain
- On foot
- Hat Sai Kaew, Ao Hin Khok, Ao Phai and Ao Phutsa link up along the shore
- Boat trips
- Slow boats circle the island and speedboats run seven-island snorkelling days
- Songthaews are dusty and add up fast; for neighbouring bays, walking is quicker.
- Carry cash for transport and food, since ATMs on the island are scarce.
Know before you go
What makes Ko Samet worth the trip, and what catches visitors out.
Why travelers love it
- Sunrise from the east-coast bays, when the sand is still empty.
- Fire twirlers on Hat Sai Kaew and Ao Hin Khok, working the beach from early evening.
- Seafood barbecues on the sand at Ao Phai after dark.
- Sunset from the south-west cliffs, a scooter ride from the main beaches.
- A seven-island speedboat trip to snorkel around Samet's neighbours.
Good to know
- ATMs are scarce and unreliable on the island, so bring enough cash from the mainland.
- A national park fee is charged on arrival; residents of Thailand with proof may pay the lower Thai rate.
- Weekends and holidays are crowded; arrive early for the best rooms.
- Restaurants that tour groups use are not always the best; walk a few doors further.

Weather in Ko Samet, month by month
Month-by-month climate figures for Ko Samet are being researched.
Northern beaches, snorkel reefs and southern coves in three days
Three days suits Ko Samet. Spend the first afternoon on the northern beaches from Hat Sai Kaew to Ao Phai, the second morning on a speedboat snorkel trip and the evening at Ao Prao for sunset, and the last day in the quiet southern coves of Ao Thian and Ao Wai.
Arrive on a morning boat so you have the pick of rooms; if you are flying in, U-Tapao airport, about 50 km west of Ban Phe, takes flights from Phuket and Koh Samui. Walk south from Hat Sai Kaew past the mermaid statue to Ao Hin Khok and Ao Phai, swim where the jet skis are fewest, and stay on the sand after dark for the fire twirlers, who work the beach between about six and half past ten.
On day two, be up for sunrise, which the east-facing bays catch head on. After breakfast, join a speedboat trip to snorkel the reefs around Samet's smaller neighbours. In the evening, take a songthaew or scooter to Ao Prao on the west coast for sunset, or ride to the cliffs along the south-west shore.
Give the last day to the south. Scooter or songthaew down past Ao Wong Deuan to the small coves of Ao Thian and Ao Wai, where a handful of bungalows share each bay and the water is calmer. Pack a picnic or eat at a bungalow kitchen, and allow plenty of time for the bumpy ride back to Na Dan and the boat to Ban Phe.
Seafood barbecues on the sand at Ao Phai and Hat Sai Kaew
Seafood barbecues on the sand are the main way to eat on Ko Samet. After dark, restaurants on every beach lay out prawns, squid, crab and whole fish on ice, sold by weight and grilled to order, with the most choice at Ao Phai and Hat Sai Kaew. Ask the price per weight before choosing.
Restaurants drag tables and cushions onto the sand, light candles, and set out ice beds of the evening's catch: prawns, squid, crab, whole fish and shellfish. Every beach has at least one barbecue.
Do not judge by crowds. Day-trip companies strike deals with particular restaurants and march their groups in, so a full house says little about the cooking. Look at how fresh the display is, ask for the price per weight before choosing, and walk a few doors along if you are unsure.
By day you barely need to move. Hawkers walk the sand with fresh fruit, grilled chicken wings, dried squid and som tam (papaya salad, which can be fiercely hot; ask for it mild). Ice cream sellers do the rounds too, at a small markup for the convenience. Most bungalow operations run their own kitchens with Thai curries and fried rice, plus the usual pizzas and burgers.
Ko Samet's beaches, from busy Hat Sai Kaew to quiet Ao Wai
Ko Samet's beaches get quieter the further south you go. Hat Sai Kaew by Na Dan pier is the busiest, Ao Hin Khok and Ao Phai suit backpackers, Ao Phutsa and Ao Thapthim are calmer, and Ao Thian and Ao Wai have a few bungalows each. Ao Prao on the west coast faces the sunset.
Hat Sai Kaew, near Na Dan pier, is a kilometre of fine sand and the busiest strip on the island, with jet skis, banana boats and rows of deckchairs. Come here for convenience, and expect loud weekends. Ao Hin Khok and Ao Phai, just south, are where backpackers go for cheap bungalows, bars handing out drink-special flyers and fire shows.
Quieter options start at Ao Phutsa and Ao Thapthim, small bays with mid-range bungalows a few minutes' walk from the action. Further down, Ao Wong Deuan is a lively crescent with its own pier, handy for speedboats from Ban Phe. After that the bays shrink to coves such as Ao Thian and Ao Wai with a few bungalows each, the best choice for couples who want silence and do not mind the ride.
If sunsets matter more, stay at Ao Prao, the main beach on the west coast, where resorts are fewer and more expensive. Whatever you choose, book ahead from November to February and June to August, the island's two busy seasons, and avoid Thai public holiday weekends.

Frequently Asked Questions (FAQs)
Quick answers to the questions travelers ask most before visiting Ko Samet.
Getting there
For most people, yes: the bus from Ekamai runs to Ban Phe in about 3.5 hours, then a ferry or speedboat to the island. Driving to Ban Phe takes about 2.5 hours.
Every route funnels through Ban Phe, the pier town on the eastern outskirts of Rayong, roughly 220 km from Bangkok. From there slow boats cross to Na Dan, the island's port, in 30 to 45 minutes, and speedboats run straight to several beaches. Drivers from Bangkok follow Sukhumvit Road (Highway 3) down the coast; turning onto Highway 36 at Bang Lamung, before Pattaya, cuts about 45 km at the cost of the sea views.
General
Hat Sai Kaew is the busiest and most convenient. For quiet, go south to Ao Thapthim, Ao Thian or Ao Wai; for sunset, stay at Ao Prao.
November to April for dry weather. Avoid weekends and Thai holidays if you want space.
Songthaews run between beaches with fares posted at each stop, or rent a scooter. The northern bays are close enough to walk between.
Fire twirlers work along Hat Sai Kaew and Ao Hin Khok in the evenings, and bars at Ao Phai put on their own shows.
Most beaches face east, so head to Ao Prao on the west coast or the cliffs along the south-west.
Yes. Operators on the island run snorkelling trips, from slow boats around Samet to speedboat tours of seven nearby islands.
One road runs down the spine of the island, concrete in stretches and a bumpy dirt track elsewhere. In the north the bays are a few minutes apart, joined by paths over the rocky points, so you rarely need a ride. Wheels earn their keep further south, where the coves are smaller and the forest thicker.
Prices & payment
Enough for the whole stay. Cash machines on the island are few and not always working, and card payment is far from universal.
Yes. Most of the island is a national park, and visitors pay an entry fee on arrival; residents with proof may pay the lower Thai rate.
Timing & weather
The slow ferry to Na Dan pier takes 30 to 45 minutes. Speedboats are quicker and can drop you at your beach.
The best time to visit Ko Samet is Nov to Apr. Dry, sunny and calm before the southwest monsoon.
- Best overall: November - April (Dry and sunny with calm seas; book ahead for weekends)
- Rainy season: May - October (Showers and choppier crossings, though Thai holidaymakers still fill the island from June to August)
Visa & documents
From 15 September 2026, Thailand replaced its 60-day visa exemption with a 30-day exemption for tourism, covering about 60 countries; a one-time extension of up to 30 days may be possible at an immigration office. Some nationalities can get a visa on arrival, and others need an e-Visa before travel. All foreign visitors must complete the Thailand Digital Arrival Card (TDAC) online before arrival.
Health & safety
Visitors to Thailand rarely run into serious trouble. Road accidents, especially on scooters, cause the most harm, followed by scams and strong sea currents in the monsoon. Ignore anyone who says the Grand Palace is closed, and swim only where no red flag flies.
