What feels different
Our editorial assessments · Select a factor to see how we scored each place.
Why we rate Koh Chang 8/10
Several long west-coast beaches make beach days easy, though the sand and swimming vary by bay and season.
Why we rate Koh Yao Yai 7/10
Several appealing beach bases and Laem Had provide strong coastal appeal, with substantial tidal and location differences.
What we assess
Beach appeal, convenient access and variety during a beach-focused stay, within the destination itself.
Why we rate Koh Chang 8/10
A mountainous rainforest interior, waterfalls and curving bays give Koh Chang more than a beach-only landscape.
Why we rate Koh Yao Yai 8/10
Green island landscapes, coastal views and the Laem Had sandbar provide a strong natural setting.
What we assess
The visual impact of natural surroundings and how central those landscapes are to a typical stay.
Why we rate Koh Chang 4/10
Fishing communities, temples and local island life add some cultural interest, but major heritage sights are limited.
Why we rate Koh Yao Yai 5/10
Village and fishing-community outings offer worthwhile local context, with less depth of major heritage sights than cultural cities.
What we assess
The variety, depth and practical access to historic places, temples, architecture, traditions and cultural experiences during a typical stay.
Why we rate Koh Chang 6/10
Seafood, Thai restaurants and familiar international meals are available along the west-coast bases.
Why we rate Koh Yao Yai 6/10
Village food and several resort restaurants provide useful choice, though dining is dispersed rather than concentrated in a large town.
What we assess
Food quality, variety, distinctive local cooking and how readily visitors can find good places to eat, regardless of price.
Why we rate Koh Chang 4/10
Beach bars and casual live music are available, but evenings are generally low-key outside a few strips.
Why we rate Koh Yao Yai 2/10
Resort bars and quiet coastal evenings are available, with few late-night options beyond the main resort venues.
What we assess
The choice, variety and liveliness of evening venues, their opening hours and how easily you can enjoy a typical night out.
Why we rate Koh Chang 7/10
Quiet beaches and forested stays are easy to find away from the busiest west-coast centres.
Why we rate Koh Yao Yai 9/10
Quiet coastal stays and an unhurried village setting are central to the island experience, with local variation around piers and resorts.
What we assess
How easily you can enjoy a peaceful stay, considering traffic, nightlife noise, crowds and practical quieter bases.
Why we rate Koh Chang 8/10
Boat trips reach nearby islands and snorkelling sites, though routes and frequency depend on season and departure bay.
Why we rate Koh Yao Yai 8/10
Arranged trips reach nearby islands and Phang Nga Bay, with weather, group size and the chosen base affecting convenience.
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 Yao Yai 6/10
A chosen resort base works with arranged transfers and taxis; exploring the spread-out island requires planning and extra rides.
What we assess
Freedom to explore without renting a scooter, using walking, public transport, taxis, tuk-tuks, ride-hailing or boats; transport price is assessed separately.
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 Yao Yai 6/10
Simple bungalows and village food are available, but the smaller budget selection and boat or road transfers add costs.
What we assess
How easily you can enjoy a typical stay on a modest budget, including simple accommodation, food, realistic transport and characteristic activities.
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 Yao Yai
Choose Koh Yao Yai if...
- Laem Had sandbar and coastal scenery
- Local village and fishing-community context
- Resort stays and arranged water-based outings
The trade-off
The island is dispersed, beaches are tide-sensitive, and a resort transfer does not provide effortless transport everywhere else.
