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".

Lying near the Hungarian and Serbian borders, Timisoara is the gateway to the West and has a long history of cosmopolitan multiculturalism. It's the birthplace of the 1989 Romanian Revolution that ended the Ceauşescu's dictatorship, an important centre in recent Romanian history. It is a green, pleasant and walkable city with cosy cafes, lively markets and interesting museums, offering plenty of entertainment to fill your time, whether you are visiting for a day or a week.

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.

Bucolic beauty envelops the small, unincorporated town of Arnold, California. Resting at the center of the 400-mile Sierra Nevada mountain range, Arnold is a breath, sigh, and smile of fresh air. Testaments to this are the mild summer temperatures, a close proximity to stunning natural wonders, and the overall seclusion of Arnold’s favored attractions.

Walking through Xi'an is like stepping back in time. The towering ancient city walls, the quiet streets around the Drum and Bell Towers, and the bustling markets all carry a sense of history. You can almost hear the whispers of ancient merchants who walked the Silk Road or feel the presence of emperors who once ruled here. Xi'an is a place where the past and present exist side by side in a way that feels both natural and humbling.
