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 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.
Koh Tao
Choose Koh Tao if...
- You want diving or snorkelling to be a big part of your holiday.
- You like small bays, coastal viewpoints and clear-water boat outings.
- You want a sociable island base with cafés, casual bars and a strong diving community.
The trade-off
The bays are separated by hills, so exploring beyond your stay area usually needs taxis, boat taxis or tours. A quieter cove can also put you farther from the main restaurants and evening scene.
