Kermabec is the long, open dune beach north of Tronoën, reached through Tréguennec and known to surfers as Prad ar C'hastell or 'Le Concasseur', after the ruins of a wartime pebble-crushing plant built for the Atlantic Wall. It picks up as much swell as La Torche with a fraction of the crowd, and the beach is so long that you can pick your own peak. The catch is that the waves close out more often and rides are usually short. The whole coast here belongs to the Conservatoire du littoral, a public body that protects it, and is backed by marshes and lagoons.

Local tips

Walk the beach and look for a sandbank where the waves peel instead of breaking all at once; with kilometres of sand there is no need to share a peak. The line-up is usually empty or nearly so, and the few surfers out are friendly. Watch for rips and for buoys and other man-made obstacles in the water.

Getting there

From the village of Tréguennec the D156 runs down to the beach at Kermabec. The surf spot is marked by a large WWII blockhouse and the crushing-plant ruins, a short walk from where you park. The dunes are low and eroding, so keep to the paths.

Travel notes

How often it works
It faces the open Atlantic in the middle of the Baie d'Audierne. So it gets waves on much the same days as La Torche, often from under a metre of swell. Above about 2 m, though, the long flat beach mostly closes out: waves break all at once.
Crowd and vibe
One of the emptiest beaches on this coast. There is usually nobody out on weekdays and only a few surfers at weekends, and they are relaxed and friendly. The beach is kilometres long, so you can find a wave to yourself even in summer.
Camping and vans
The nearest campsite is the 3-star Camping Kerlaz in Tréguennec village, about 3.5 km inland. Camping de la Torche in Plomeur is around 5 km south. The beach has only a sandy car park, and the whole shore is protected land. Nearest campsite about 3.5 km away.
Facilities
There are toilets but no showers or drinking water, and lifeguards in July and August from 1 to 7 pm. For cafés, shops and surf schools, go to the villages or La Torche.
Water quality
The French health authority (ARS) rated the water at Kermabec excellent every year from 2022 to 2025.
