# Circuito Sur de Oriente

The Circuito Sur de Oriente (CSO), meaning "Southern Circuit of the Orient", is a west-east highway connecting Bayamo to Santiago de Cuba, through Manzanillo, Niquero and the southern coastal side of eastern Cuba, below the Sierra Maestra mountain range. Also known as Circuito Guacanayabo-Sur de Oriente, because it crosses the Gulf of Guacanayabo, the name Oriente (meaning "Orient"), refers to the ancient and former Oriente Province. With a length of 347 km, it is the fourth-longest Cuban highway after the "Carretera Central", the "Circuito Norte" and the "Circuito Sur".

## Route
### Description

It crosses the shore of the Gulf of Guacanayabo, and the section to Niquero centre continues to Cape Cruz, through Playa Las Coloradas, in Desembarco del Granma National Park.
* The 6-20, also known as "Carretera de Pilón" and "Carretera Granma", runs from the fork to Niquero to Santiago de Cuba, through Pilón, Marea del Portillo, Uvero and Chivirico (seat of Guamá municipality).
