Kravica Waterfalls, Bosnia

Hidden in Europe’s last jungle along Bosnia’s Trebižat River is a series of waterfalls set in spectacular scenery. “The entire area is exceptionally green with chaste trees, poplars and figs,” says Samer Hajric, mountain guide and program coordinator. “The rock and tuff formations host thick lichen, moss and grass, giving them an emerald colour – there are hardly any man-made formations near the falls to interfere with the natural environment.” While the Kravice waterfalls are not big in terms of size, they are comparable to Krka or Plitvice National Parks in Croatia, but are less busy, explains Hajric.
Valley of the Moon, Chile

Located in Los Flamencos National Reserve in northern Chile’s Atacama Desert, Valle de la Luna (valley of the moon) is one of the country’s most unique locations. The shimmering sand dunes and moon-like sculptures make for a dramatic landscape. “No other place in the world can be compared to this one, with no water, no fauna, and no flora,” says travel manager, Malcolm Parkinson. “There are salt flats, geysers, altiplanic lagoons and volcanoes,” says Parkinson.
Lake Natron, Tanzania

This serene-looking lake set in northern Tanzania is so corrosive that it is believed the water can burn the skin and eyes of animals that are not adapted to it, turning them into mummies. The water alkalinity comes from the sodium carbonate and other minerals that flow into the lake from the surrounding hills as well as from the mineral rich hot springs that feed the lake. Shallow (less than three metres) but vast (56 kilometres long), Lake Natron boasts an average temperature of 40° Celsius and an abundance of cyanobacteria, a bacterium with red pigment, which gives the lake its characteristic red and orange glow. Despite its saltiness, the lake is home to a thriving ecosystem and serves as a breeding ground for about 2.5 million Lesser flamingos (a species of flamingos) who thrive on the cyanobacteria.
