La Plagette is one of the best places in Cap d'Agde to observe the deposits of Agde volcanism. Outcrops of grey tuff and yellow tuff reveal the different layers left by volcanic projections. They originate from explosive eruptions that occurred just over a million years ago. A stop that allows you to read the geological history of the site directly in the rock.

The panorama that unfolds before you is the legacy of intense volcanic activity. The first eruptions of the Agde complex began here, at Mont Saint-Loup, approximately 950,000 years ago. They would end some 50,000 years later with those of Petit Pioch. Despite the time that has passed, the landscapes of Cap d'Agde retain the imprints of this exceptional geological history.
