About Miyagi Channel
Miyagi Channel is a boat-access channel dive between Miyagi and Heianza Islands that rewards experienced divers with clear water and a strong sense of structure. The mooring drops quickly into a deep corridor with coral on the slopes, goatfish near the entry, and the chance of bigger fish farther out. Plan it as a deeper Okinawa dive rather than a casual reef swim, and keep an eye on weather and boat timing.
