Quick answers
Which local rescue or training agency should I check first?
Use the local lens: coastguard/federation norms and the shop briefing for that bay — not a blog visibility claim.
What is Jellyfish Lake?
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.
When was the shark sanctuary declared?
2009. Palau banned shark fishing in its EEZ; the policy is a tourism and conservation sentence visitors still hear in briefs.
What is the Palau Pledge?
A 2017 immigration-stamped promise to the children of Palau about environmental conduct. It is branding and a legal culture, not a dive card.
Is Chandelier Cave a cavern?
An overhead limestone cave near Koror, typically dived with a guide and an exit plan. Treat it as overhead, not as a swim-through toy.
Do people need a liveaboard?
Many famous sites are day-boat range from Koror. Peleliu and some Rock Island circuits are longer days. Liveaboards exist; they are not mandatory.
Palauan reef knowledge is older than tourism. As a destination the story runs through Japanese-era charts, postwar wrecks (including Peleliu's 1944 battlefield waters), and a 1990s-2000s liveaboard fame that Blue Corner still carries.
The history is a current point that became a national brand, then a sanctuary statute.

Eras
- Customary — Belau — Reefs as law and food.
- Mandate / war — Charts and wrecks — A military layer tourists still dive.
- 1970-2009 — Liveaboard fame — Blue Corner as a global name.
- 2009-now — Sanctuary state — Sharks, pledge, UNESCO.
Milestones
- Blue Corner as a hook-in site — A technique that became a destination.
- Shark sanctuary 2009 — Policy as brand and as law.
- UNESCO 2012 — The Rock Islands as a listed landscape.
- Palau Pledge 2017 — Etiquette at the airport stamp.
Palau as a destination is a current and a statute. The lakes are older than the stamp.
