Sintra, located just 40 minutes from Lisbon, feels like a world apart. Tucked into the hills of the Serra de Sintra, this town has drawn kings, poets, and explorers for centuries. It was once the summer retreat of Portuguese royalty, who left behind palaces and gardens that seem pulled from a storybook. The most famous, Palácio da Pena, is perched high above the town with bold red and yellow towers that blend Romanticism with Moorish and Gothic styles.

Tristan da Cunha is a remote volcanic island in the South Atlantic Ocean, forming part of a small archipelago along with Inaccessible Island and Nightingale Island. Known as the most isolated inhabited island in the world, it is accessible only by a week-long boat journey from South Africa.

Manama pulses with stories from long ago and today. Just beyond the modern skyline lies Qal’at al‑Bahrain, a layered mound once the capital of Dilmun, used by societies from the Kassites to the Portuguese. Visitors can climb its crumbling stairways and imagine life across centuries there. Nearby, the Bahrain National Museum, opened in 1988 in a stately waterside building, displays archaeological finds from ancient Dilmun to modern-day artifacts and is one of the Gulf's first modern museums.
