Micronesian reefs and a jellyfish lake: Blue Corner currents, a 2009 shark sanctuary, and the Palau Pledge stamped in 2017. Palau is a western Pacific island nation whose recreational water story is the Rock Islands, a few world-famous current dives, and Ongeim'l Tketau (Jellyfish Lake). The Rock Islands Southern Lagoon became a UNESCO World Heritage site in 2012.
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.
Check each criteria to confirm findings against the atlas verdict.

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. Ongeim'l Tketau, a meromictic marine lake in the Rock Islands where golden jellyfish are snorkelled under strict fins-and-sunscreen rules. It is not a scuba site and has closed for ecological reasons.
2009. Palau banned shark fishing in its EEZ; the policy is a tourism and conservation sentence visitors still hear in briefs. A 2017 immigration-stamped promise to the children of Palau about environmental conduct. It is branding and a legal culture, not a dive card.
This is a reading check for the atlas, not personal advice, a live price, or a booking. It does not replace the full topic page.
