Easier exploring without a scooter
Walkable beach areas, songthaews and boat transfers cover many visitor needs, though cross-island trips take coordination.

What feels different
Our editorial assessments · Select a factor to see how we scored each place.
Why we rate Koh Chang 8/10

Why we rate Koh Chang 8/10

Why we rate Koh Chang 8/10

What we assess
The variety of worthwhile sea-island trips, convenient departures, journey times and flexibility under normal operating conditions.
Why we rate Koh Chang 5/10
Shared songthaews and organised trips cover popular stops, but routes are limited and the island’s steep, spread-out roads constrain flexibility.

Why we rate Koh Chang 7/10
Local eateries and a range of guesthouses help with value, while ferry transfers and island transport add to the total.
Why we rate Koh Samet 6/10

Scores out of 10 · Higher means more of that characteristic About these scores
How to read the scale
Scores run from 0 to 10 and describe how strongly a destination offers each characteristic.
Higher does not always mean better
A higher nightlife score means a livelier scene. A higher quietness score means a calmer atmosphere. The right balance depends on your trip.
Close scores mean similar experiences
Small differences should not decide your trip on their own.
Koh Chang
Choose Koh Chang if...
- You want a beach holiday with rainforest and waterfall outings too.
- You like a green, mountainous island with several different beach bases.
- You prefer casual beach evenings and quieter stays over a major party scene.
The trade-off
The island is spread out, with steep roads between some areas. Shared taxis and organised trips help, but beach-hopping and independent exploring take more planning than on a compact island.
Koh Samet
Choose Koh Samet if...
- You want an island beach break within reach of Bangkok.
- You want a choice of white-sand bays, with livelier beaches and quieter places to stay.
- You like seafood, beach bars and relaxed evenings by the water.
The trade-off
Popular beaches can be busy and stays cost more on weekends and holidays. Choose your beach carefully if quiet evenings matter, and include boat transfers and park fees in your budget.
