Nestled along the south bank of the Danube, this historical Austrian city bursts with charm. A favorite stop on European river cruises, the city's most famous attraction is Melk Abbey, which dates back to the 11th century. The original Benedictine structure was lost to fires and foreign invasion, then rebuilt during the 18th century in lavish Baroque style, including a library and inner church covered in magnificent frescoes and gilded fixtures.

Sighisoara rises above the Târnava Mare River as one of the few medieval citadels in Europe that is still lived in and admired today. Its historic center has been on the UNESCO World Heritage List since 1999, recognized for its long history as a fortified Saxon settlement and its role in trade and defense on the edges of central Europe. Wander through cobbled alleys framed by pastel-colored houses, and the layers of time feel close at hand, from the city walls and guild towers to busy cafés.

Fitzroy Island sits off the coast from Cairns in Queensland, Australia, rising from the Coral Sea with rainforest and beaches that draw visitors year-round.

Located about twenty-five miles southwest of Rapid City, South Dakota, lies Mount Rushmore. Following Highway 244 from the west leads to the orientation center. There exhibits tell how sculptor Gutzon Borglum carved away twice the rock needed to construct Egypt's Great Sphinx (which isn't even as tall as Washington's nose).

Yellowstone National Park, America's first national park, stands as a stunning testament to nature’s raw power and beauty.
