Rio San Juan Department

Rio San Juan Department is one of fifteen (15) departments and two (2) autonomous regions in Nicaragua. Rio San Juan Department is the southern-most department and is bordered by Lake Nicaragua to the West, the Atlantic Ocean to the East, and the country of Costa Rica to the South.

The capital of Rio San Juan Department is the city of San Carlos, Nicaragua which is located where the San Juan river meets Lake Nicaragua.

The Indio Maiz Biological Reserve covers a large portion of the eastern end of Rio San Juan Department. It is home to an extremely wide variety of animals, insects, and plants and is therefore an attraction for both tourists and scientists from around the world. However, large portions of the Indio Maiz Biological Reserve are off-limits to tourists. For safety reasons, it is wise to hire a local guide if you are going to try to explore this untouched rain forest.

Rio San Juan Department also contains portions of Lake Nicaragua including the Solentiname Archipelago, which consists of 36 islands. Mancarroncito Island, Mancarron Island, San Fernando Island, and La Venada Island are the four largest islands of the Solentiname Archipelago and are very popular tourist attractions that have many things for tourists to see and do as well as numerous options for accommodations.
