The path around this pond is well laid out and very pleasant to walk! Lots of birds to observe!

This is where the ponds connect thanks to a system of hammer mills. Sometimes, when the water level is low, you can walk along the small exchange canal; otherwise, you have to take the short walk.

An impressive rock. One of the last rock formations that you can see before you continue west and you only see the flat Camargue.

The first part of the road from Fos is dangerous and unpleasant, you have to arrive at the Salins de Giraud to find a safe and quiet route, and to be able to enjoy the beautiful landscapes of the Camargue.

A bridge runs right through the Etang de lÈstomac. The church of Fos sur Mer is perched on a hill in the middle of the marshes
