Tombelaine, Tidal island in Mont Saint-Michel Bay, France
Tombelaine rises 45 meters above sea level and extends 250 meters in length, featuring granite formations that date back to the Cambrian period.
English forces utilized the island as a strategic military base in 1423 during their attempts to capture Mont Saint-Michel during the Hundred Years War.
The name Tombelaine derives from ancient Celtic words meaning 'little mountain' in reference to its smaller size compared to Mont Saint-Michel.
Access to the island requires careful timing with tide schedules and guidance from local experts to ensure safe passage across the bay.
The French state purchased Tombelaine in 1933, leading to its classification as a historic monument in 1936 and designation as a bird reserve in 1985.
