Le Gouffre

Le gouffre de Plougrescant is a coastal granite formation on the Breton Atlantic shore. The site features a complex arrangement of rock formations, sandy barriers, and water channels shaped by tidal movements and ocean surges.

The site formed through marine erosion that has worked on Precambrian rocks for millions of years. These erosion processes carved out the rocky features and water basins that define the landscape today.

The name comes from the deep chasm created by natural forces over millions of years. Visitors today can observe how the sea has shaped the granite and which plants thrive in this distinctive coastal setting.

Visit during low tide to see the rock formations and water basins clearly exposed. Wear sturdy shoes as the granite surfaces can be slippery and the ground is uneven throughout the site.

The site contains brackish lagoons connected to the ocean through pebble beds, creating an unusual water environment. This brackish mixture supports plant and animal species that cannot survive in purely salt or fresh water elsewhere.
