The Magdalena Strait is the narrowest part of the river at 2.20 m, after 70 km on the way from the source to the mouth. The slopes consist of more than 70 million years old compacted lava from the volcanoes of "Pelota" and "Purutal". The reddish color of some rocks is due to the presence of iron sulphate in the area.

It's hard to believe that a river more than 1500km long can fit through such a narrow gap (about 2m). But that's how he gets strong and vigorous for his long voyage into the Atlantic. The Cordillera in the San Agustín area is a special watershed. Within a few kilometers it is decided whether the water will flow into the Pacific (Rio Cauca), down the Amazon basin or over the Rio Magdalena into the Atlantic.
