Nicaragua is the largest country in the Central American isthmus. Nicaragua’s capital, Managua, is the country’s largest city and the third-largest city in Central America. The multi-ethnic population of six million includes indigenous peoples, Europeans, Africans and Asians. While the main language is Spanish, native tribes on the eastern coast speak their own languages. Nearly one fifth of Nicaragua is designated as protected areas like national parks, nature reserves, and biological reserves. The biological diversity, warm tropical climate and active volcanoes make Nicaragua an increasingly popular tourist destination.
