A Valentine in the Arabian Sea. Maldives

Heart-shaped islands are more common than you might guess and can be found at many latitudes and longitudes. This one in the archipelago nation of the Maldives is hard to top for its beauty. A flight over this tropical gem might make for the most memorable Valentine's Day ever.

The Republic of Maldives lies about 470 miles southwest of the Indian subcontinent. The country is made up of 26 atolls, together containing more than 1,000 islands. It's the smallest nation in Asia by land area, although it covers 35,000 square miles if you count its waters.

A popular destination among honeymooners, the Maldives derives most of its income from tourism. However, its days as a tropical getaway might be numbered as it faces the threat of climate change. With an average elevation of just under 5 feet, the country is especially vulnerable to rising sea levels. If you need a reason to care about global warming, just keep this precious spot close to your heart.
