The three main Gulf of Thailand islands — Koh Samui, Koh Phangan, and Koh Tao — each have a distinct character and are connected by frequent ferries. Together they make one of Southeast Asia\’s most complete island-hopping routes: a big resort island, a party-and-wellness island, and a diving island, all within a short boat ride of each other. This guide covers the full route, ferry connections, and how to approach it from Malaysia.

Practical Tips
- Book ferries 3–7 days ahead in peak season (December–February) — particularly Koh Tao routes which sell out
- Full Moon Party timing: Check the monthly dates before booking — accommodation and ferries around Full Moon are 2–3x harder to get
- Lomprayah combo tickets cover multiple legs and are often cheaper than buying separately
- Motorbikes: Available for rent on all three islands — essential on Koh Phangan and Koh Tao, less necessary on Koh Samui where taxis are plentiful
- ATMs: All three islands have ATMs but Koh Tao\’s can run out of cash in peak season — bring enough THB from Samui
