The town lies on the River Gardon or Gard, and is a short distance downstream of the Roman aqueduct Pont du Gard, in nearby Vers-Pont-du-Gard.
The current bridge over the Gardon in the town itself was completed in 1994, the successor to two previous suspension bridges. The remains of the first, built in 1830 by the Seguin brothers, are visible on the left bank.
