At the end of the 19th century, in the port of Le Couregant, whose slipway was built in 1894, very large quantities of fish and tons of salt were landed.
This part of the Ploemeur coastline is also of strong ecological interest, explaining the existence of two protected natural areas, one at the Pointe du Talud towards Kerroc'h and the other near the Courégant. Existing heathlands are classified in the inventory of heathlands in France. The presence of several regionally interesting species has been recorded, such as Asphodelus macrocarpus, the marsh Gentian, the green-winged orchid, clumps of tor-grass, western gorse and bell heather and dorset heath.
This site is an observation area for many sea birds (gannets, shearwaters, penguins, terns) and wading birds keeping to the creeks including the purple sandpiper which is quite rare. The diversity of shapes of the cliffs, creeks, beaches, dunes, moors and lawns, makes this coastline a very beautiful maritime landscape in the Pays de Lorient.
