Koh Samet vs Koh Chang: Which Island From Bangkok?

Two of the easiest island escapes from Bangkok sit along the same eastern coast, yet they suit very different trips. Koh Samet is the quick weekend fix — close, easy, small. Koh Chang is the bigger adventure — greener, wilder, further away. If you’re weighing one against the other, here’s an honest head-to-head so you can pick the right island before you book the car.

The short version

Koh Samet is about 3 hours from Bangkok and needs only a short ferry. Koh Chang is roughly 5 hours plus a car ferry, and it’s a much larger, more mountainous island. Samet rewards a short trip; Chang rewards a longer one. Both are covered in our pillar on day trips & transfers from Bangkok — but these two are really overnight islands rather than same-day round trips.

Travel time and logistics

Koh Samet is the closest proper island escape to the capital. The road leg runs about 220 km / 3 hours to Ban Phe pier in Rayong, then a short ferry or speedboat across — roughly 40 minutes on the scheduled ferry, or 15 by speedboat. There’s no vehicle ferry involved; you leave the car on the mainland and cross as a foot passenger. Full detail lives in our Koh Samet ferry guide.

Koh Chang is further southeast, close to the Cambodian border in Trat province. The road leg is roughly 310 km / 4.5–5 hours to the ferry piers (Ao Thammachat or Centre Point), then a car ferry of about 30–45 minutes that carries your vehicle right onto the island. That’s a real advantage: your driver can take you door-to-door to your resort on the far side of the water. We walk through the whole crossing in the Bangkok to Koh Chang car-ferry guide.

So the trade is simple. Samet is faster and simpler but you switch to a passenger boat. Chang takes longer but the car comes with you, which is a big deal if you’re travelling with a family and luggage.

Beaches and scenery

Koh Samet is small and dry, with a string of pretty white-sand coves along its east side — Sai Kaew, Ao Phai, Ao Wong Deuan. The sand is genuinely fine and white, the water clear, and everything is close together, so you can walk or take a cheap songthaew between beaches. It feels compact and social.

Koh Chang is Thailand’s third-largest island: a spine of rainforest-covered mountains, waterfalls inland, and longer beaches spread down the west coast (White Sand Beach, Klong Prao, Lonely Beach). It feels remote and green rather than compact. You’ll want transport to move around, and the sense of scale is part of the appeal.

Nightlife and vibe

Koh Samet leans lively and easy — beach bars, fire shows on Sai Kaew, a weekend crowd escaping Bangkok. It’s busy but never sprawling, and because it’s so close it fills up on Thai public holidays.

Koh Chang has more range. White Sand Beach is the busier resort strip, Lonely Beach is the backpacker party corner, and much of the rest of the island is quiet, low-key and nature-focused. If you want to disappear for a few days, Chang gives you that; if you want an easy buzzy weekend, Samet delivers it faster.

Family-friendliness

For families, the deciding factor is often that car ferry. On Koh Chang the driver takes you straight from Bangkok to the resort with no reloading of bags onto a passenger boat — smoother with young kids and lots of luggage, and the calm west-coast beaches suit families well.

Koh Samet is still very doable with children — the crossing is short and the beaches are gentle — but you do handle the foot-passenger transfer and the songthaew hop to your beach. For a quick two-night trip that’s a fair trade; for a week with small kids, Chang’s door-to-door ease often wins.

Cost of the private car leg

The road transfer is the part you organise in advance; boat tickets are bought locally. Rough private-car starting fares:

• Bangkok to Koh Samet — from ~1,900 THB per car (to Ban Phe pier; ferry ticket separate). See Bangkok to Koh Samet.
• Bangkok to Koh Chang — from ~3,700 THB per car, including the car ferry, delivered to the island. See Bangkok to Koh Chang.

Chang costs more, but that fare covers a longer drive and the vehicle ferry, and it drops you at your resort rather than at a mainland pier — so you’re comparing pier-drop against door-to-door, not just distance.

Side-by-side comparison

	Koh Samet	Koh Chang
Distance from Bangkok	~220 km	~310 km
Total travel time	~3 hours	~5 hours
Boat crossing	Passenger ferry/speedboat (~15–40 min)	Car ferry (~30–45 min)
Car comes across?	No — foot passenger	Yes — driven to resort
Island size	Small, compact	Large, mountainous
Scenery	White-sand coves, dry	Rainforest, waterfalls, long beaches
Vibe	Lively, social, weekend	Ranges quiet to party
Best for	Short trip / weekend	Longer stay / a week
Extra fee	National park fee on arrival	—
Private car from	~1,900 THB (to pier)	~3,700 THB (incl. car ferry)

Note one Samet extra: it’s a national park, so there’s an entry fee collected on the island (higher for foreign visitors, children discounted). Keep some cash handy — it’s separate from the boat ticket.

Pick Samet if…

• You have only a weekend or a night or two.
• You want the quickest, cheapest route to real white sand.
• You like a compact, social island where everything is walkable.
• You’re flying in and want to be on the beach the same afternoon.

Pick Chang if…

• You have several days or a full week to settle in.
• You want door-to-door ease with the car ferried across — ideal with family and luggage.
• You prefer green, mountainous, more remote scenery over a busy strip.
• You want the choice of quiet nature or a party beach on the same island.

Either way, the one thing worth sorting before you go is the road leg. Book Bangkok to Koh Samet for the quick weekend, or Bangkok to Koh Chang for the door-to-door island week — and we’ll handle the drive while you enjoy the view.
