Koh Yao Yai to Koh Mook Ferry: What to Expect
This is an island-to-island crossing rather than a mainland transfer, so your journey depends on which boats are currently running between the two piers. Because Koh Yao Yai is not a major transport hub, connections to Koh Mook are often limited or seasonal, and combined transfers via a mainland pier may be the more reliable option depending on the time of year.
Transport Options
Several transport modes may be available for this route, depending on the season and operator schedules:
- Ferry services connecting the two islands
- Speedboat or longtail boat options
- Combined transport packages involving minivan or bus transfers to/from departure ports
- Private transfer arrangements
Availability varies by season, as some operators adjust schedules during monsoon periods. Check current options when you book to confirm which services are running.

From Koh Yao Yai, ferries typically depart from the main pier or designated port area on the island. You'll arrive at Koh Mook's main pier, which serves as the central transport hub for the island.
