Coiba spent most of the 20th century as something nobody visits on purpose: a penal colony. The prison kept developers away for decades — and accidentally preserved the largest island in Central America as pure wilderness. Since 2004 the prisoners are gone; since 2005 it is a UNESCO World Heritage Site.

Why divers whisper about it

Coiba sits in the same marine corridor as the Galápagos and Cocos Island. Translation: white-tip sharks on almost every dive, mantas, huge schools, whale sharks and humpbacks in season. Snorkelers get their share too — Granito de Oro islet is the classic.

How it works

The honest part

This is an expedition, not a beach day: long boat rides, sun, early starts. The water is Pacific — visibility varies with season. But if you want the version of Panama that feels like a nature documentary, nothing else comes close.
