About Koh Yippon Yai

Koh Yippon Yai is the bigger of the two "Japanese islands" in Ang Thong. Its reef system mirrors Yippon Lek with good coral coverage and regular fish life. The dramatic limestone cliffs above water create a stunning backdrop for surface intervals. Often combined with Yippon Lek on the same snorkel trip.

Tips

Snorkel both Yippon islands on the same trip. The passage between them can have mild current.
