Band-e-Amir National Park is located in Bamiyan Province, Afghanistan. It features a series of six deep blue lakes formed by natural calcite dams, with many beautiful waterfalls. For $5 you can rent a brightly colored swan paddle boat to explore the impossibly blue lakes. The lakes freeze solid in winter, making wondrous walls of ice. It is Afghanistan's first national park, where families camp and have fun, though vacations are still expensive for most Afghan families.
