The golden stretch of beachbreaks between Longville and La Tranche is a little snap shot of what Les Landes to the south offers. Dune backed peaks varying from mellow and crusiey to hollow and punchy, depending on the banks, accessed via a series of those classic beach cuts throughs on the edge of the pines that let you know you're in France. Les Conches can get busy as there's a big car park nearby, but can be a good indicator for what's happening at the rest of the Longville beaches. Works through the tides, high can often be more walling. Heading south towards Bud Bud the banks pick up more swell, serving up greater consistency and punch per inch. Further south La Terriere has a good vibe and often good banks plus beach parking. In huge swells and higher tides La Pointe du Grouin (Le Phare) can offer up some fun long rights.
