Get lost in Cartagena's Old-World atmosphere on a 4.5-hour trip around San Felipe fortress that leads into a guided Old Town stroll. Stand at the bottom of a harbor-side hill before Castillo San Felipe de Barajas, a Spanish-built fortress and UNESCO World Heritage Site. Listen to tales of pirates and admirals who invaded the citadel's maze of tunnels since the 1500s. Your narrated walking tour then continues into the walled Old Town of Cartagena, where a spectacle of Colonial relics remains today. Admire the Torre de Reloj clocktower, once the main entrance into the old city, and see the town's oldest church in Plaza Santo Domingo. Watch local dancers and musicians perform in shady Plaza Bolivar corners and gaze upon the grand mansions lining Plaza de la Aduana. Enjoy some free time to stroll the old city streets with the help of a map provided by your tour guide.
