Sint Eustatius

'The Caribbean's Hidden Treasure' – the tourism slogan of tiny Sint Eustatius (more commonly known as Statia) is especially apt. The jewels of this castaway-style outpost lie under the sea: dazzling reefs, teeming marine life, rusting wrecks and vestiges of the Lower Town – part of the capital (and only town), Oranjestad – which is now largely submerged.
