If you are near Nimes in the South of France, a visit to the Pont du Gard Aqueduct is a must! The Romans really knew how to built things that would last, as this is one of the best preserved Roman aqueducts in existence.
The Pont du Gard Aqueduct makes an ideal day trip from Nimes by car or by bus. We saw many French families there enjoying an afternoon of swimming and picnicking underneath the impressive structure. If hiking is your thing, there are a plethora of hiking trails up in the hills around the aqueduct for you to explore.
