Sioux Falls is South Dakota’s largest city, located in the southeastern part of the state along the Big Sioux River. The river is central to the city’s landscape, most notably where it passes over a series of pink quartzite ledges at Falls Park. Around the urban area, the terrain opens into the broad prairie of the Great Plains, with farmland and gently rolling countryside extending beyond the city.
Novi Sad, Serbia’s second-largest city, sits along the banks of the Danube River and has long served as a cultural meeting point in the Balkans. Its centerpiece is Petrovaradin Fortress, a massive 18th-century stronghold nicknamed the "Gibraltar on the Danube." The fortress is known not just for its historic architecture but also for its network of underground tunnels and the iconic clock tower where the hands are reversed, meaning the large hand shows the hour.
Tonto National Forest covers a large area of central Arizona, stretching across desert lowlands, rugged mountains, pine forests, and river corridors north and east of the Phoenix metropolitan area. Its varied elevation creates several distinct landscapes within one forest, from saguaro-filled Sonoran Desert to ponderosa pine country around the Mogollon Rim.
In the central highlands of Mexico lies a rich city, with a culture as colorful as its past. Guadalajara, Mexico's second largest city, may be best known for its tequila, mariachis and the hat dance, all part of its celebrations. The downtown area is dominated by a huge public square, the Plaza del la Liberacion. Guadalahara's most impressive historical sights are found along this square, as well as museums tracing Mexico's long history.
Ninh Binh, located about 100 kilometers south of Hanoi, offers a landscape shaped by limestone karsts, winding rivers, and flooded rice paddies.

At Trang An Scenic Landscape Complex, boat routes pass through caves, ancient pagodas, and valleys surrounded by towering cliffs. Local rowers often use their feet to paddle, an unusual technique that surprises many first-time visitors.
