Iguazu Falls, Brazil/Argentina

One of the world's most stunning natural wonders, Iguazu Falls is a series of magnificent waterfalls located on the Iguazu River, straddling the border between Brazil and Argentina. This chain of voluminous cataracts varies between 200 to 269 feet (60 to 82 meters) in height and extends for more than a mile along a crescent-shaped cliff before plunging over a plateau with thunderous roars. Estimated in number between 275 and 300, the waterfalls are divided by numerous islands. While some of the cascades rush over ledges, creating dazzling sprays of mist and rainbows, others plummet straight down into a long, narrow gorge called the Devil's Throat. The falls in and of themselves are a breathtaking spectacle, but their beauty is all the more enhanced by the surrounding lush forest teeming in exotic wildlife like parrots, toucans, macaws, spotted jaguars, monkeys, butterflies and vivid blooms of begonias and wild orchids.

Machu Picchu, Peru

Machu Picchu (Spanish pronunciation: [ˈmatʃu ˈpiktʃu]) or Machu Pikchu ([ˈmɑtʃu ˈpixtʃu]), is a 15th-centuryInca citadel situated on a mountain ridge 2,430 metres (7,970 ft) above sea level. It is located in the Cusco Region, Urubamba Province,Machupicchu District in Peru,^[3] above theSacred Valley, which is 80 kilometres (50 mi) northwest of Cuzco and through which the Urubamba River flows.

Most archaeologists believe that Machu Picchu was built as an estate for the Inca emperor Pachacuti (1438–1472). Often mistakenly referred to as the "Lost City of the Incas" (a title more accurately applied to Vilcabamba), it is the most familiar icon of Inca civilization. The Incas built the estate around 1450 but abandoned it a century later at the time of the Spanish Conquest. Although known locally, it was not known to the Spanish during the colonial period and remained unknown to the outside world until American historianHiram Bingham brought it to international attention in 1911.

Although it was located only about 80 kilometers (50 mi) from the Inca capital in Cusco, the Spanish never found Machu Picchu and so did not plunder or destroy it, as they did many other sites. Over the centuries, the surrounding jungle overgrew the site, and few outside the immediate area knew of its existence. The site may have been discovered and plundered in 1867 by a German businessman, Augusto Berns. Some evidence indicates that German engineer J. M. von Hassel arrived earlier. Maps show references to Machu Picchu as early as 1874. In 1911 American historian and explorer Hiram Bingham travelled the region looking for the old Inca capital and was shown to Machu Picchu by a local farmer. Bingham brought Machu Picchu to international attention and organized another expedition in 1912 to undertake major clearing and excavation. 

Bingham was a lecturer at Yale University, although not a trained archaeologist. He organized the 1911 Yale Peruvian Expedition in part to search for the Inca capital, which was thought to be the city of Vitcos. Bingham asked local people to show them Inca ruins. By the time they camped at Mandor Pampa, with Huayna Picchu 2000 feet above them on the opposite bank, they had already examined several ruins, but none fit the descriptions of Vitcos. 

At Mandor Pampa, Bingham asked farmer and innkeeper Melchor Arteaga if he knew of any nearby ruins. Arteaga said he knew of excellent ruins on the top of Huayna Picchu. The next day, 24 July, Arteaga led Bingham and Sergeant Carrasco across the river on a log bridge and up the Huayna Picchu mountain. At the top of the mountain they came across a small hut occupied by a couple of Quechua, Richarte and Alvarez, who were farming some of the original Machu Picchu agricultural terraces that they had cleared four years earlier. Alvarez's 11-year-old son, Pablito, led Bingham along the ridge to the main ruins. The ruins were mostly covered with vegetation except for the cleared agricultural terraces and clearings used by the farmers as vegetable gardens.

Machu Picchu is tangible evidence of the urban Inca Empire at the peak of its power and achievement—a citadel of cut stone fit together without mortar so tightly that its cracks still can’t be penetrated by a knife blade. The complex of palaces and plazas, temples and homes may have been built as a ceremonial site, a military stronghold, or a retreat for ruling elites—its dramatic location is certainly well suited for any of those purposes. The ruins lie on a high ridge, surrounded on three sides by the windy, turbulent Urubamba River some 2,000 feet (610 meters) below.

Scholars are still striving to uncover clues to the mysteries hidden here high in the eastern slopes of the Andes, covered with tropical forests of the upper Amazon Basin. Machu Picchu appears to lie at the center of a network of related sites and trails—and many landmarks both man-made and mountainous appear to align with astronomical events like the solstice sunset. The Inca had no written language, so they left no record of why they built the site or how they used it before it was abandoned in the early 16th century.

Landscape engineering skills are in strong evidence at Machu Picchu. The site’s buildings, walls, terraces, and ramps reclaim the steep mountainous terrain and make the city blend naturally into the rock escarpments on which it is situated. The 700-plus terraces preserved soil, promoted agriculture, and served as part of an extensive water-distribution system that conserved water and limited erosion on the steep slopes.

The Inca’s achievements and skills are all the more impressive in light of the knowledge they lacked. When Machu Picchu was built some 500 years ago the Inca had no iron, no steel, and no wheels. Their tremendous effort apparently benefited relatively few people—some experts maintain that fewer than a thousand individuals lived here.

In 1911 a Peruvian guide led Yale professor Hiram Bingham up a steep mountainside and into the history books as the first Western scholar to lay eyes on the “lost city” of Machu Picchu. While indigenous peoples knew of the site, Peru’s Spanish conquerors never did—a fact which aided Machu Picchu’s isolation, and preservation, over the centuries.

Today Machu Picchu is far from isolated. In fact it’s a must-see for any visitor to Peru and the draw that compels many to travel to that nation. Machu Picchu’s management challenge is preservation of the site while making it accessible to all those who hope to experience an incredible part of Inca history. Source: Wikipedia

Inca stone work is incredible. One of these carved stones is estimated to weigh 300 tons, has 13 sides
 tightly fitted to other stones with no cement and no crack can be penetrated by even a credit card.

Paradise on Earth - Maldives

The tiny country of the Maldives in the middle of the Indian Ocean is made up of about 1,200 tiny coral islands grouped into 26 atolls. The word atoll actually comes from the the Dhivehi (a language spoken on the Maldives) word “atholhu” With the highest point above sea level being around 6 feet (2 meters), the Robinson Crusoe life style is everywhere you look. The primary activity on the Maldives is scuba diving and snorkeling. The atolls are all coral reefs hundreds of miles away from any major landmass, meaning that water clarity is excellent and underwater life is abundant. Manta rays, sharks, even a few wrecks, you name it, you can find it in the Maldives.
