The harbor is a key site for the local 'langoustine' (Norway lobster) fishery, which is a staple of the Trégunc maritime economy.
The adjacent Étangs de Trévignon are a series of coastal lagoons separated from the sea by narrow strips of sand, creating a unique brackish ecosystem.
The Pointe de Trévignon serves as a natural boundary between the Bay of Concarneau to the west and the coastal stretches leading toward Névez.
The harbor area is part of the 'Natura 2000' network, a European scheme designed to protect rare and vulnerable species and their habitats.
The coastline here consists largely of 'trevoux,' a local term for the specific rock formations found in this part of Southern Finistère.
The Port of Trévignon is a functioning small-scale fishing harbor located on the southern coast of Finistère, Brittany, known for its focus on landing fresh crustaceans and line-caught fish. It serves as a gateway to the Pointe de Trévignon, a headland that marks the transition between the rocky coastline and the dune-backed sandy beaches of Trégunc. The port area features a breakwater structure that protects local small boats from the Atlantic tides. Adjacent to the harbor are protected coastal ponds and marshlands known as the Étangs de Trévignon, which are designated as a sensitive natural area. Visitors can observe the daily return of fishing boats and the subsequent direct sale of catches at the quayside. The coastal path, known as the GR34, runs directly through this port area, connecting it to surrounding beaches. The landscape is characterized by its granite bedrock and salt-sprayed flora typical of the Breton coastline.

Check the tide charts before visiting, as the character of the harbor and the nearby beaches changes significantly at low versus high tide.
Visit during the late afternoon to catch the arrival of local fishing vessels unloading their daily harvest.
Bring sturdy walking shoes if you intend to hike the GR34 coastal trail beyond the port.
Do not attempt to swim near the harbor entrance due to strong tidal currents and boat traffic.
Respect the work of the local fishermen and do not block the quays or access ramps when boats are unloading.
