Lake Toba is another of the island's spectacular sights - a remarkable volcanic crater set in the middle of northern Sumatra, 176km from Medan. The lake is huge (the largest in South-East Asia), occupying the caldera of a giant volcano that collapsed on itself after a massive eruption some 100,000 years ago.

Querétaro, located in the heart of central Mexico, is a city where centuries of history are still visible in daily life. Its historic center, a UNESCO World Heritage Site, features narrow streets, elegant plazas, and baroque churches that reflect its colonial past. One of the city’s most iconic landmarks is the massive aqueduct, built in the 18th century with 74 stone arches stretching nearly a mile across the landscape.

Nashville is a small town in Brown County, southern Indiana, surrounded by the wooded hills and winding roads of the region. It is best known for its concentration of independent shops, art galleries, craft studios, restaurants, and locally made goods, with much of the commercial district located within a few blocks of the town center. The surrounding countryside is markedly different from Indiana’s flatter agricultural landscapes, with steep ridges, narrow valleys, and forested slopes.

Girdwood is a small community in south-central Alaska, located within the Municipality of Anchorage between the Chugach Mountains and Turnagain Arm. The valley is surrounded by steep mountains, glaciers, temperate rainforest, and open wetlands, creating a landscape that changes noticeably with the seasons.

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.
