Gilmaan Wall

Vertical wall running north-west from Yap Caverns, full of crevices and overhangs, with large brown porites and daisy corals; with a running current yellow soft coral blooms under ledges at about 21 m. Clown triggerfish are sometimes seen near the base of the wall, and its position near the southern tip brings plenty of fish.

Facts

• Region: Micronesia – Yap, Pohnpei & Kosrae

• Permit: Yap's reefs and lagoon are held under customary village ownership, so diving needs the permission of the owning community, normally arranged by your dive operator. A 2017 conference presentation reported that operators pay villages access fees (e.g. US$300 per month for Goofnuw Channel, US$2 per diver at Stammtisch) and that other sites need permission but no payment. No official fee schedule could be found – ask your dive centre; the Yap Visitors Bureau can advise.
