Not sure where to go? Find my destination
A stronger beach offering
A broad choice of beaches reachable by road lets you pick lively resort strips or quieter sands. Different coasts and bays suit different beach days. Another assessed advantage: a livelier nightlife scene.
A small advantage for keeping costs down
Simple stays and local meals make a modest-budget holiday realistic. Keep room for boat outings and transfers, especially when exploring beyond your stay area.

Why we rate Koh Samui 9/10
A broad choice of beaches reachable by road lets you pick lively resort strips or quieter sands. Different coasts and bays suit different beach days.
Why we rate Krabi 7/10
Excellent beaches around Railay and Phra Nang reward a visit, though reaching them from Ao Nang generally requires a boat.
What we assess
Beach appeal, convenient access and variety during a beach-focused stay, within the destination itself.
Why we rate Koh Samui 8/10
Palm-lined coasts, a green interior and waterfalls give you scenery beyond the beach. Viewpoints and inland outings add variety.
Why we rate Krabi 9/10
Limestone cliffs, coastal caves and dramatic bays make the landscape a central part of your stay.
What we assess
The visual impact of natural surroundings and how central those landscapes are to a typical stay.
Why we rate Koh Samui 5/10
Temples and the old shophouses of Fisherman’s Village add cultural interest. The island offers fewer extensive historic quarters than Thailand’s cultural cities.
Why we rate Krabi 5/10
Tiger Cave Temple and community visits around Krabi Town and Ao Nang add cultural interest. These experiences are spread out, so plan outings beyond the beach.
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 Samui 8/10
Southern Thai food, seafood, markets and international restaurants give you a varied dining scene. Good meals are available well beyond luxury resorts.
Why we rate Krabi 7/10
Town markets and resort restaurants offer a useful mix of local food and visitor-friendly dining.
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 Samui 8/10
Chaweng’s lively venues, beach clubs and cocktail spots offer a substantial evening scene. Other bases suit more relaxed nights.
Why we rate Krabi 6/10
Ao Nang offers bars and evening dining for a lively night out, with a more relaxed feel than a dedicated clubbing holiday.
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 Samui 6/10
Quieter coasts and relaxed beach bases are available, but traffic and lively resort strips mean choosing an area carefully.
Why we rate Krabi 7/10
Quieter coastal bases make a relaxed trip easy to plan. Central Ao Nang can still be busy, so your choice of accommodation matters.
What we assess
How easily you can enjoy a peaceful stay, considering traffic, nightlife noise, crowds and practical quieter bases.
Why we rate Koh Samui 8/10
Ang Thong excursions and connections to nearby Gulf islands offer varied boat days and multi-island trips. Departure points and journey lengths differ.
Why we rate Krabi 9/10
Ao Nang is a convenient starting point for trips to nearby islands, with plenty of coastal scenery along the way.
What we assess
The variety of worthwhile sea-island trips, convenient departures, journey times and flexibility under normal operating conditions.
Why we rate Koh Samui 7/10
Taxis, arranged transfers and tours make a scooter optional, especially from a well-chosen base. Cross-island outings usually need a ride and some advance arrangement.
Why we rate Krabi 7/10
Stay centrally in Ao Nang to keep restaurants, the beach and boat departures close by. Inland sights and other bases still need arranged transport.
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 Samui 6/10
Local meals and simple stays keep a modest budget possible. Ground transport and boat outings can make the full holiday costlier than the room price suggests.
Why we rate Krabi 7/10
Simple stays and local meals make a modest-budget holiday realistic. Keep room for boat outings and transfers, especially when exploring beyond your stay area.
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 Samui
Choose Koh Samui if...
- You want a choice between lively beach areas and quieter island stays.
- You enjoy markets, seafood and varied restaurants alongside the beach.
- You want varied beach days and island exploring, with boat excursions such as Ang Thong as an option.
The trade-off
Exploring different beaches usually means arranging rides, which can add to your budget. Chaweng’s lively scene and the quieter coasts offer very different stays.
Krabi
Choose Krabi if...
- You want limestone scenery and opportunities for rock climbing.
- You want boat excursions from Ao Nang to nearby islands and the Railay area.
- You want beaches alongside hot springs and national park visits.
The trade-off
From Ao Nang, reaching Railay and Phra Nang means a boat trip. Stay on Railay for those beaches nearby, but expect boat transfers when exploring beyond the peninsula.
