Tips for the Railay to Koh Yao Yai Crossing
- Koh Yao Yai (Klong Hia Pier) and Koh Yao Noi (Manoh Pier) are separate stops about 2.7 km apart across the channel, often served by the same Bundhaya boat a few minutes apart. Check that your ticket names the right island.
- Bundhaya’s island-hopping routes are seasonal: most start between 15 October and 1 November and stop in early or late May, and they disappear from its booking search outside those dates.
