At Aux Bouissounades, the sports course follows this stream, in a landscape entirely structured by the Mare. On foot or by bike, this section mainly offers a moment of respite, in the shade of the banks and wooded slopes.

From here, you benefit from a very clear view of the Haut-Languedoc mountains. You can also see the Pyrenees as a backdrop stretching from one end of the horizon to the other.

These public toilets are a life saver! Clean washbasins and drinkable water. Filled all my bottles and made it back to Beziers! Thank you to Andreas!

As far as I know, there is only one restaurant on the tour, "La Clairière Restaurant bistronomique. Cambon et Salvergues" in Cambon. It's good that in Cambon there is also the possibility to refill drinking water at the public toilets.
