Direction to the Grand Sillon beach
The presentations are made, the departure is given and our small group of 36 people heads towards the big beach of the Sillon. A first break is necessary just in front of the breakwaters and Yann takes out a large marine map from his bag. The walk starts with a reading of the landscape, to which he includes some very interesting anecdotes about the history of Saint-Malo, the reason of the breakwaters which are not only used to break the waves and the tides in the bay of Saint-Malo. Some questions are already coming up but Yann does not answer them all. Several steps further on, we learn a little more about the little people who live in the tidal zone, between the sand worm and his compatriots, used to live 6 hours with their nose in the air and 6 hours with their gills in the water. The green. dark blue and light blue parts of the marine map soon have no more secret for us.
It is an almost lunar landscape of rocks covered with algae that offers itself to us.
Finally, we arrive on the area of the lowest seas, the one that discovers only during exceptional tides, at the spring and autumn equinoxes. It is an almost lunar landscape of rocks covered with seaweed that offers itself to us. Cautiously, with our feet in the water, we begin to fish on foot. We started to turn over the rocks in order to observe all this marine fauna and flora. Yann makes us test a seaweed with a subtle peppery taste and explains us that a big part of these brownish seaweeds which populate the foreshore is found in some of our desserts!
