With its 6.50 meters height, the Lannoulouarn menhir does not go unnoticed. Bordering the small road, it marks the landscape and recalls the presence of an ancient archaeological site. Formerly, a series of five other megaliths stood.

Among the three abers in the Pays du Léon, the Aber Benoît is the second largest at 31 kilometers long. Navigable, you can see the sailboats as far as the port of Tudgibus. Fresh water mixing with sea water provides an environment conducive to the cultivation of oysters and mussels.

An “aber” in Breton means “ria” in French, meaning a narrow, elongated and relatively deep bay. Here, the aber-Benoît perfectly meets this definition. The site, particularly pretty, is crossed by a single Tréglonou bridge.

The Aber Benoît is the discreet little brother of the Aber Wrac’h. South of Lannilis and Landéda we discover here, from its narrower mouth, an arm of the sea which magnifies the river. Between green hillsides and agricultural land, it is good to walk there to slow down and savor the tranquility of the place all in glaz nuances (a typical Breton color which variegates the waters of the coast. It recalls the movement of the waves, the color of the sky, the interior of the abers in blue, green and gray tones).
