UNESCO World Heritage Sites were created to celebrate and safeguard the most unique places around the world. Below are my 4 favorite UNESCO World Heritage Sites.
Cinque Terre, Italy
With cars banned here, you’ll really get to feel the unique history and character of the Cinque Terre’s five centuries-old coastal villages. The breathtaking views of harbors（港口）far below the wild coastline along with the rich colors will definitely make it a memorable holiday.
Angkor Wat, Cambodia
Angkor Wat is the world’s largest religious（宗教的）monument and it contains impressive remains from the Khmer Empire（9th to 15th century）. The site has dozens of iconic temples like Ta Prohm（a magnificent temple ruin hidden in the jungle）. Hosting more than two million visitors annually, this artistic masterpiece is a must-see site.
Petra, Jordan
Petra’s rock-cut architecture has contributed to its nickname, the Rose City, based on the color of the stone it was carved from. The delicate constructions of temples and tombs along with the remains of churches and temples are only a couple of reasons why this world-famous site is a must-visit destination.
Yellowstone National Park, USA
Yellowstone’s vast wilderness includes mountain ranges, lakes and waterfalls. One of the main reasons for tourists to visit Yellowstone is to observe the amazing wildlife like grizzly bear, bison, bighorn sheep wander the plains and valleys.
