Guatemala has many popular tourism destinations, including Izabal, known as the "green Caribbean" for its coastal diversity, featuring Rio Dulce, Lake Izabal, and San Felipe Castle. Semuc Champey in Alta Verapaz features seven stepped pools fed by natural springs. Antigua Guatemala is considered the jewel of Guatemalan tourism and architecture as it was built to replace another city and now preserves colonial architecture, making it one of the most visited places in the country.
