World's Prettiest Places

Taj Mahal
India
Molded out of red sandstone and white marble, and sparkling with the glint of semi-precious stones, this mausoleum of northeastern India needs no justification to appear on our list. Frommer's says, "It's not just the perfect symmetry, the ethereal luminescence, the wonderful proportions, or the sheer scale," that makes us revere the Taj Mahal. It's also "the exquisite detailing covering every inch of marble that justifies it as a wonder of the world." Its amorous background also feeds our admiration: It was commissioned by a 17th century Mughal emperor to honor the memory of his favorite wife, Mumtaz Mahal. Consider planning a trip for sometime between October and March to behold Taj's majestic domes, chambers and minarets; that way the weather will be somewhat cooler for walking around. If you have time, stay from the early morning until the late night, as "the radiance of the Taj under the moonlight is beyond any explanation," notes TajMahal.org.uk.




Croatia
Plitvice Lakes National Park

Our next selection is largely unknown to tourists from the United States, and perhaps that makes it even more precious. The limestone cavesPlitvice Lakes National Park of the Plitvice Lakes National Park make the water of its 16 lakes and a handful of waterfalls shimmer brilliant shades of turquoise, silver and green. And to get a better view the lakes' beauty, you'll find a web of wooden plank walkways scattered throughout. But note that there is no true best or worst season to stop by this site in central Croatia. Snow and ice transforms the area into a winter wonderland; in summer the surrounding trees further enhance the hues of the lake water. If at all possible, though, avoid the onslaught of local tourists in July and August.




The Great Barrier Reef
Australia


Australia's luscious islands, cays and coral reef system of the Great Barrier Reef are awesome in scope and visuals -- in fact, this reef covers more of the world than any other entry on our list (approximately 135,000 square miles; the only living thing visible from outer space). All who encounter even a small portion of this gorgeous giant are dazzled by its aquamarine waters and honeycomb beaches. Even more beauty awaits you below the water surface: a maze of more than 2,900 spectacular coral reefs and countless marine life. Come to this area just off the coast of Queensland between June and October, so you can avoid the worst of Australia's oppressive heat.
