Cartagena de Indias reigns as the crown jewel of Colombia’s Caribbean coast — not for checklist attractions, but for its sheer atmospheric magic. Within its 16th-century stone walls (built to repel pirates like Sir Francis Drake), the city unfurls as a living postcard: pastel-hued colonial buildings, salsa rhythms spilling onto cobbled streets, and horse-drawn carriages clattering past vibrant plazas. By day, the scent of fried plantains and coconut rice fills the air; by night, rooftop bars hum with rum cocktails and sea breezes.

The Blue Mountains get their name from the natural blue haze created by vast eucalypt forests in this World Heritage area. Tiny droplets of oil released from the trees mix with water vapour and sunlight to produce the distinctive colour. Enjoy crisp mountain air, beautiful panoramas, charming villages, one of the world’s oldest cave systems, and exhilarating adventures in the Blue Mountains, near Sydney. You can even see dinosaur trees in the Blue Mountains Botanic Garden, Mount Tomah. This is a great Australian escape and a natural wonder of the world.

Part of the Balearic Islands, Ibiza is a jewel of the Mediterranean Sea. Famous as the world’s clubbing capital, the island also offers stunning natural beauty, a perfect climate, and UNESCO World Heritage Sites. Whether you’re here to dance to world-class DJs, relax by crystal-clear waters, explore hidden coves, or unwind on vibrant beaches, you’ve certainly come to the right place.

The narrow and often steep granite-paved streets of Cagliari’s Castello District are a reminder of a bygone age when the town was dominated at first by Pisans, and later by the Aragonese. Built from white limestone, the walls and towers of the Old Town shimmer in the sun and are a magnificent sight, especially if you are lucky and approach the city from the sea, as the English novelist D.H. Lawrence did in 1921 when he described the Old Town as looking like a "Jerusalem without trees".
