Presqu'île Saint-Laurent

Presqu'île Saint-Laurent is a coastal peninsula in Finistère that juts into the Iroise Sea, connected to the mainland by a narrow strip of land. The terrain features rocky cliffs and small coves along its shoreline.

The peninsula contains Neolithic remains, including a dolmen registered in 1923 and menhirs that form ancient stone circles. These monuments show that people lived here during prehistoric times.

Ancient goémon ovens built from flat stones show the seaweed farming tradition that once provided soda ash for iodine production. These stone structures remain visible across the peninsula today.

Access the peninsula through parking areas at Plage des Dames or Biscuiterie des Abers, with a full loop taking around 45 minutes. The terrain is walkable for most visitors, though wearing sturdy shoes is advisable.

The straight-line distance from this peninsula's tip to Rio San Luigi in Menton spans roughly 1083 kilometers. This measurement represents one of the longest direct lines possible within mainland France.
