3 Must-See Hop-off AttractionsDon't have time to hop-off at every bus stop? Don't panic! The first recommended bus stop is Pastelillo at Bus Stop 2, located right on the Marina of Cartagena. Originally the Fort Boquerón, it was the first fort to be built in Cartagena in the 16th century to defend themselves from possible attacks. Although it's only small, you can enjoy the breath-taking views of the sea and go for lunch at the Club de Pesca! Another exciting landmark is the San Felipe Castle at Bus Stop 4, a fortress built on the top of the San Lázaro hill in the 17th century. Last but not least, hop-off at Cartagena Castillo Grande at Bus Stop 13. Take a walk along the marina and soak up the sunshine!
