Discovery of the abyss of Plougrescant

Discover the chasm in all seasons!

Gouffre de Castel Meur, Pointe du Château

Cut-out shoreline, fringed with reefs, bristling with rocky knolls, such is the surprising spectacle offered around the site of the Gouffre.
Over time, the landscape has been gradually transformed. Complex swell phenomena have led to accumulations of pebbles which have lengthened to give birth to tombolos.
The tombolos are transverse pebble cords linking the land to islets.
On the site of Plougrescant, it is a system of three pebble cords which enclose two lagoons of brackish water. These lagoons, which communicate with the marine environment through the pebble strips, are of great interest from a botanical point of view.

Erosion phenomena affect the rocks in different ways depending on their composition. Here, the granite, less degraded, forms rocky heaps called granite chaos.

Discovery of the site of the Gouffre

Anne-Sophie, Romane or Lucie will reveal the history of the site of the Gouffre through its geology and will make you discover, through its fauna and flora, the multitude of environments that have been created in this protected natural space. An enchanting stroll on a preserved portion of the coastline that retains its wild aspect. A bit of nature leaving you dreaming and calling on your imagination… particular shapes will perhaps take shape before your eyes.
