Koh Samui vs Phuket
Both islands offer beaches, nightlife, restaurants, tours, luxury resorts, and plenty of activities, but they have very different personalities.
Phuket is significantly larger and more developed, while Koh Samui can feel easier to explore and retains a distinctive island atmosphere.
Neither is automatically better. The right choice depends on what kind of holiday you're looking for.

Small choices can help protect the island.
