Easy hiking trails around Étang de Lavalduc offer access to a distinctive natural landscape in the Bouches-du-Rhône region of France. The area is characterized by the unique iridescent pink-blue waters of the lake, a phenomenon caused by high salt content and specific crustaceans. Surrounding the main lake are other ponds, such as Étang du Pourra and Étang de l'Engrenier, which also display a pink coloration. The terrain is generally undeveloped, providing tranquil routes for walking and nature observation, often featuring Aleppo pines and views of historical sites like the Oppidum of Saint-Blaise.

U-turn in the oppidum because it is surrounded by fence then impassable path in the descent above the Etang du Pourra, charred trees and many branches on the way... So some parts to avoid especially in VAE ...

The Etang du Pourra offers beautiful views and it has the originality of being sometimes dry! It can be seen from the heights or from the path that runs along its shore.

The oppidum of Saint-Blaise is one of the region's most important archaeological sites. Here the traces of human settlement reach back to the 5th millennium BC. Salt was traded on the Opidium in the 7th century. A very exciting destination! The oppidum can be visited free of charge from Tuesday to Sunday. From the 1st of June to the 30th of September the visit is limited due to forest fire danger. Whether the visit is approved can always be requested the day before. Information can be obtained from the Tourist Office of the Département on 0 811 20 13 13.
