    StandoutExceptional marine biodiversity

    Main Channel in Yap is exactly what it sounds like: a busy thoroughfare. We typically see grey reef sharks cruising through, often in good numbers, along with schools of jacks and barracuda using the current to their advantage. It’s a drift dive, so be comfortable with moving water. This site suits divers who appreciate active shark encounters and don't mind a bit of a ride.

    Safety Notes

    Drift dive - carry a surface marker buoy (SMB) and stay with your group. Brief the current direction before entry.

    Always perform a 3-minute safety stop at 5m before surfacing.
