In this part of the Doubs department, the Loue river makes many meanders and is very calm. It evolves between forests and meadows and in fact, helps to make this part of the department even more bucolic.

The Port-Lesney bridge crosses the Loue, a river in the Val d'Amour. It is a perfect place for swimming and walking. This bridge replaces the stone bridge which dates from the 15th century, the remains of which can be appreciated.
