Hi Jann,
Found this on another website. Depart from pier and walk to Panoramic Lift for an elevator ride to Esplanade de Banderas where you can enjoy views of city and visit Interpretation Center of Cartagena to learn about history and culture of city. Walk back down to street level and continue your walking tour along the old streets, admiring the local architecture along the way. See city highlights that include San Francisco Square, Mayor Street and a visit the Roman Theater
