The deciding factor: what it costs to get there
Choose Phuket if you want an easy, cheap landing and a buffet of activities; choose Koh Samui if you want a calmer resort island and will pay a premium for the quiet. The deciding factor is the journey, and it is not close. Koh Samui's airport is privately owned by Bangkok Airways, which holds a near-monopoly on direct flights and keeps one-way fares around $100. Phuket has a busy international airport served by AirAsia and other budget carriers, so getting in is both cheaper and more flexible.
Three concrete points decide the rest:
- The budget back door to Samui: fly into Surat Thani for $20–35 on a low-cost carrier, then take a Lomprayah catamaran transfer (around 600 THB) to Nathon pier, saving $50–100 over flying direct.
- Signature day trips: from Phuket, Maya Bay reopened in October 2025 with a 400 THB national park fee and boats now docking at Loh Samah Bay; from Samui, the Ang Thong marine park (42 islands, 35km west) is the standout boat tour.
- Nightlife: Phuket has Patong's Bangla Road; Samui keeps it to Chaweng's quieter strip.
