San Antonio de los Cobres is a high-altitude town located in the Los Andes Department of Salta Province, Argentina. Situated at approximately 3,775 meters (12,385 feet) above sea level, it serves as a gateway to the Puna de Atacama region and is a key stop on the Tren a las Nubes (Train to the Clouds) railway line. The town's name, which translates to "Saint Anthony of the Coppers," reflects its historical association with copper mining in the surrounding Sierra de Cobre. Today, San Antonio de los Cobres is known for its indigenous culture, traditional weaving, and as a starting point for tourists embarking on one of the world's highest train journeys. ​ The Tren a las Nubes is a renowned tourist train that traverses the rugged terrain of the Andes, culminating at the Viaducto La Polvorilla. This impressive steel viaduct, located about 13 kilometers from San Antonio de los Cobres, stands at an altitude of 4,220 meters (13,845 feet) above sea level. Spanning 224 meters in length and reaching a height of 63 meters, the viaduct is a testament to early 20th-century engineering. Constructed between 1930 and 1932 under the direction of engineer Richard Maury, it was designed to overcome the challenging topography of the region. Today, the Viaducto La Polvorilla remains a highlight of the Tren a las Nubes experience, offering passengers breathtaking views of the Andean landscape. ​

Maasai Mara, frequently spelled Masai Mara, and referred to locals as just "The Mara," is a sizable national game reserve in Kenya's Narok County that borders Tanzania's Serengeti National Park. The Maasai people, the region's original occupants who came from the Nile Basin, are honored by the name. From a distance, their description of the region is as follows: "Mara" means "spotted" in the Maa language due to the short, bushy trees that are scattered throughout the terrain. With its populations of lions, leopards, cheetahs, and African bush elephants, the Maasai Mara is one of Africa's wilderness and wildlife protection areas. In addition, it is home to the Great Migration, which has earned it a spot among the ten Wonders of the World and the Seven Natural Wonders of Africa. Depending on the weather, the Great Migration often takes place in July when a huge number of wildebeest migrate from Tanzania across the Mara River. The Maasai Mara National Reserve, the Mara Triangle, a number of Maasai group ranches, and Maasai Mara conservancies are all included in the Greater Mara ecosystem. The Masai Mara, sometimes referred to as "the world's eight world wonders" or one of the most well-known wildlife places in the world, is home to an abundance of species, breathtaking views, and unending plains.The Masai Mara National Reserve, an unfenced reserve with unrestricted wildlife movement, and a number of conservancies comprise the Greater Masai Mara area. Maasai families privately own these parcels of land. The Maasai families who lease their property to safari lodges have the opportunity to use the money they make from the conservancies to fund development or education projects in their communities. The Masai Mara was called in honour of the Maasai people, the traditional residents of the area. 'Mara' means'spotted' in Maasai (Maa) dialect. It won't be difficult to comprehend how the Masai Mara gained its name after visiting. The terrain does appear somewhat'spotted' due to the small, bushy trees that dot it. The environment of the Greater Masai Mara is enormous. It is almost 1510 square kilometers in size. The Serengeti National Park in Tanzania is adjacent to the Maasai Mara, a sizable game reserve in Narok County, Kenya. It is named after the Maasai people, who were the original occupants of the region, and how they described it from a distance: "Mara" means "spotted" in the Maasai language, referring to the numerous trees, plants, cloud shadows, and animals that dotted the terrain.
