Do you know there are 890 UNESCO World Heritage Sites around the globe? These special places have been chosen based on cultural or natural heritage, and because they have outstanding universal value. Sixteen new sites were added just last month.

Because Italy has 44, more than any other country, About.com's guide to Italy, Martha Bakerjian, has put together a carnival travel blog listing dozens of them. Click on her UNESCO World Heritage Sites blog and you'll find links to articles and pictures galleries of special places ranging from the Palace of Versailles in France and Yellowstone National Park to Machu Picchu, Peru and Petra, the Lost City of Stone in Jordan.

This month's National Geographic magazine has a wonderful picture of a tree-wrapped temple at Angkor, Cambodia, on the cover, with the teaser: "Angkor - Why an ancient civilization collapsed." Angkor, an archeological national park stretches across 400 square meters, is a world heritage site. Researchers now believe that Greater Angkor covered more than 400 square miles, author Richard Stone reports in his article.

Visitors come to see the ruins of intricately decorated temples from the Khmer empire, especially Angkor Wat. Here's what some of the temples and nearby fishing villages look like. Photo: L Friedland

Zak Sunderland's parents may not have been happy when he came to them saying he wanted to sail around the world alone, but they were supportive. Zak, then 16, bought a 32-foot sailboat with money he earned from various jobs, fixed it up and named the boat Intrepid. He left Marina del Rey, California in mid-June and is now about 400 miles from home. You can follow the tale of this sailor, who turned 17 on the boat and is determined to become the youngest person to ever sail around the world. Read his blogs, which he has been filing throughout the journey, on his website, Zak Sunderland.
