Rondinara Bay, Shell-shaped bay in southern Corsica, France.

Rondinara Bay is a Mediterranean inlet in Corse-du-Sud, halfway between Bonifacio and Porto-Vecchio. Its beach forms a rounded shell shape, with pale sand along the lower shore and low, scrub-covered hills meeting the water at a mostly rocky shoreline. A few sailboats and small motorboats float offshore, and pale buildings stand among trees on the far shore.

The bay developed through marine sediment accumulation that created a tombolo linking an offshore island to mainland Corsica. This geological process over time shaped the shell-like form visible in the landscape today.

The bay's name comes from the rounded, shell-like curve of its beach, a shape Corsican speakers call rondinara. Above the shore, the wooded maquis gives way to the small brackish pond of la Prisarella, edged with rushes and closed off by a dune. Around 18 hectares of the site are protected by the Conservatoire du littoral.

The bay is reached via a paved road from the T10 highway, with parking available near the beach and rental services operating during summer. Access is straightforward, making this a convenient destination for day visits.

The bay's shell shape comes from a tombolo: sand accumulated until it linked an offshore islet to the Corsican shore. Above the beach, a wooded maquis leads to the small brackish étang de la Prisarella, fringed with rushes and closed off by a dune. About 18 hectares of the site are protected by the Conservatoire du littoral.
