This ecological tour takes you to Cartagena’s mud volcano, known for its healing properties. The mud is rich in minerals like aluminum, magnesium, calcium, sulfur, and iron. Despite the volcano’s 6,100-foot depth, the dense mud makes it impossible to sink.

You’ll also visit the Pink Sea, an outdoor salt mine in Galerazamba. The sea’s pink hue comes from brine shrimp, which thrive in the salty waters.
