Iguazu National Park is located within a rainforest, about 800meters above sea level, and is South America's second largest biodiversity reserve, although it's only 35% of what it was 100 years ago due to rampant development. There are over 2000 species of flowers, 150 plants per hectare, 400 species of birds, and a huge variety of mammals, reptiles, and insects. The remaining areas are like green islands, stretched between farms, plantations, pine forests, trails, and ever-expanding cities.
Within the great forest there is an innumerable amount of tourist attractions for all tastes. The Iguazu Falls are just one of many natural wonders that you can't stop visiting.
