Perched at the Triple Frontier, where Brazil, Paraguay and Argentina meet, Puerto Iguazu is linked to Brazil by the Tancredo Neves bridge. It is home to the Museum of Images of the Jungle, the Mborore Museum, a bird rehabilitation center and the famed Iguazu National Park. The National Park is home to 275 waterfalls, including the world-renowned Iguazu Falls, which plunges 270 feet. A subtropical climate means it's warm in winter and hot in summer, with temperatures soaring up to 104°F.

Located in the South Pacific more than 2,000 miles off the Chilean coast, Easter Island’s not the easiest place to reach. (If you’re interested, the easiest access is by air from Santiago or Tahiti.) But isolation has helped preserve the 1,500-year-old mysterious congregation of volcanic rock sculptures (maoi) that’s the island’s biggest claim to fame. After exploring the unique landscape, relax on an uncrowded beach and ponder one of the most mysterious places on Earth.
