Plage de la Source slots itself into a fold of the Côte de Jade, small enough that you can scan the entire strand from the promenade above but generous enough for a full afternoon. The beach earns its name from a freshwater spring that once bubbled near the sand—now tamed by the town—but the wildness persists in the tide's twice-daily retreat, which leaves behind glossy kelp, mussels clinging to black stone, and shallow pools where hermit crabs scuttle. Granite boulders frame both ends, their surfaces pocked and sea-smoothed, popular perches for teenagers and photographers waiting for the light to shift.
“A spring-fed cove where Pornic's medieval harbor meets open Atlantic horizons, granite-edged and perpetually family-claimed.”

The water stays calm inside this natural cove, protected from the swells that hammer beaches farther north. You wade in over a mix of sand and small round stones, the Atlantic cool even in July, and swim parallel to families floating on inflatables. In late afternoon the beach empties slightly, locals arriving with baguettes and thermoses to claim the benches above, turning to face west as the sun drops toward the Noirmoutier channel.
Pornic's fishing-village charm—half-timbered houses, a medieval castle, sardine boats motoring past the old port—wraps around the beach. You can walk the coastal path in either direction, limestone cliffs giving way to hidden coves, or climb back to the cafés along the waterfront where menus list moules-frites and Muscadet served in stemmed glasses beaded with condensation.
