Posada Caracol, Venezuela
This petite guesthouse opens on to the dazzling beaches of Gran Roque in Los Roques Archipelago National Park. Whitewashed throughout, the building lets the peacock hues of the ocean outside take the spotlight, but there are bursts of colour from the blue-painted shutters to jugs of tropical flowers. Focusing on simple luxuries, there are stylish rattan chairs, hammocks and a terrace where fresh fish and Italian fare are served.

Cayo Espanto, Belize
The azure waters off the Belizean coast are studded with idyllic, laidback islands and atolls, but none are quite so exclusive as Cayo Espanto. The private island is home to just six villas (all but two of which come with private plunge pools), which all face the water. Menus are tailored to each guest and might include whitefish tacos on the veranda or parrotfish with blackened corn and plantain mash on the jetty. Activities range from the laid-back (spa and birdwatching) to the lively (diving and kayaking).

Crusoe Island Eco Spa, Chile
Robinson Crusoe Island was renamed in honour of the Scottish sailor Alexander Selkirk who was marooned here, reputedly inspiring Daniel Defoe's novel Robinson Crusoe. Today the island's facilities are rather more developed than Selkirk endured, although it still retains a rugged, natural charm that has seen it protected as a world biosphere reserve. Upping the luxury quotient is the Crusoe Island Eco Spa, which offers rustic-chic, wood-panelled rooms, a gourmet restaurant and outdoor hot tubs.
