The Esmeraldas River is a 210 kilometers (130 miles) river in northwestern Ecuador that flows into the Pacific Ocean at the city of Esmeraldas. Among its tributaries is the Guayllabamba River which drains Quito. Charles Marie de la Condamine sailed up it and then climbed the Andes Mountains when on the Ecuadorian Expedition that left France in May 1735.
