Lac de l'Arguenon

The 200-hectare Lac de l'Arguenon is an artificial lake created by a dam in the commune of Plorec-sur-Arguenon. Surrounded by a forest, it boasts a wealth of flora and fauna, including sylvie anemones, violets, wood hyacinths, cormorants, grey herons and black-headed gulls.

For anglers, pike-perch and big perch are well represented, as are white fish and carp up to 24 kg.

A 19km signposted hiking trail leads around the lake from Pléven.
