Start off this activity with a safety briefing at the pier next to San Sebastián de Pastelillo fortress. Head with your guide across the channel and enjoy in the stunning view of the clock tower as soon as you are in front of the Pegasus pier.  Enjoy the company of a professional bilingual guide who is very familiar with the coastline around Cartagena. On this 3 km ride, you will discover a different side of Cartagena that is unknown to most of the people.  Expand your knowledge about the history of the city as you pass by the main sights. Understand how the old city walls were important to keep invaders out of the city.  Pass by the Camellón de los Mártires, the convention center and cross the Román bridge into the San Lázaro lagoon. See the mangroves that are located along the only part of the wall over the sea.  Towards the end, you will reach Bird's island which is another mangrove inhabited by countless birds singing as the tour strolls along.
