description Isthmus of Giens Overview
The Isthmus of Giens is a double tombolo located in the Var department of southeastern France, linking the Giens peninsula to the mainland near the town of Hyères. This geographic landform consists of two parallel, sandy sediment bars that are separated by a shallow, central lagoon of brackish water. It represents one of the only double-bar tombolo formations in the Mediterranean Sea, making it a notable subject of geographical study. While the surrounding coastline is heavily developed with residential areas, the central wetlands remain protected as ecological habitats for local and migratory bird populations.
