Palau in 2009: Rock Island use

Wow factor sits at the top of this atlas. Accessibility is low: long flights, liveaboard or day-boat logistics, and sites like Blue Corner that punish poor buoyancy in current. Risk is real because of current, boats and overhead caves, not because the lake is a decompression problem.

This chapter is a place atlas, not a certifying agency, not medical advice, and not a live briefing. Koror operators, the Palau International Coral Reef Center and the day's current override any sentence here. Destination pages are season and access notes — not a booking engine. Visa, park fees and live weather beat brochure months.

Pick the matching craft page (snorkel/scuba/surf) before the flight. Palau mapped for mechanisms, locale notes and limits. Palau sits in the places atlas — mechanisms, locale notes and limits, not slogans. Adoption and meaning follow coastal and inland water sites as much as peak specs.
