Choupal National Forest

Choupal National Forest is a national forest in Coimbra, Portugal. It is a short distance from the city downtown and runs alongside the Mondego River. The forest has trails for jogging, walking, cycling and horse-riding.This grove of poplar trees, was planted in an attempt to stop the floods of the Mondego river. In 1791, the engineer and Padre Estêvão Cabral directed a big project that was meant to decrease the levels of silt in the river. The trees of Choupal were therefore planted to allow a better settling of the riverbed. Since the 19th century many other trees, including planes, beeches, laurels, and eucalyptus have grown in the area. Today the forest is a popular place for recreation, exercise and picnics.
