La Mosson, which gives its name to a district of the city and to the football stadium, is well known to Montpellier residents. Its banks are also the ideal place to enjoy nature a stone's throw from the city center.

Highlight • Natural Monument

If there are in fact two sources in Grabels, the source of the Avy located on the left bank of the Mosson is the main one and offers a pleasant stroll.
