Nicaragua is the largest and most sparsely populated of the Central American countries. It has both a Pacific and a Caribbean coastline, two large lakes (Lake Nicaragua and Lake Managua) and a string of prominent volcanoes - two of the largest of which actually form an island (Ometepe Island) within Lake Nicaragua. Many of Nicaragua's volcanoes, such as Cerro Negro and the perfectly conical Momotombo, provide challenging objectives for day-hikes and the country as a whole has lots to offer as a destination for adventure travellers. The capital city of Managua, together with one or two other Pacific Lowlands cities (Leon and Granada, for example) have a great deal of Spanish colonial heritage, including colonial architecture and artifacts. There are extensive rainforest reserve areas and the bird and animal life is spectacular - colourful parakeets, toucans and macaws are amongst the most dramatic species. Nicaragua also has some low-key beach resorts, with perhaps the most laid-back to be found on the paradise island of Little Corn, tucked away in an isolated corner of the Caribbean.
