Morning breaks gently in West Papua. After a breakfast of spicy curry and unfamiliar fruits, guests step onto a skiff loaded with paddleboards and dry bags, then skim across glassy waters toward Pianemo, an archipelago of limestone dollops rising straight from the sea, their sides swaddled in dense jungle. With every paddle stroke, the color beneath shifts from cerulean to teal to aquamarine — so clear that coral heads and darting fish appear suspended in midair.
