The Grande Conque beach is distinguished by its amazing black sand, a testament to the volcanic history of Cap d’Agde. Nestled at the foot of the cliffs, this small cove offers a beautiful contrast between the dark rock and the blue waters of the Mediterranean. Offshore, you will see the rocks of the "Deux Frères", emblematic of the site. Note that the beach is not supervised.

Erected in 1858 at the foot of the ancient ramparts, this monumental fountain is the work of Montpellier sculptor Auguste Baussan. The statue crowning it represents Agathé, the personification of the Greek city of Agde, accompanied by three lionesses who symbolically watch over the city. The ensemble combines three remarkable materials: the Carrara marble of the statue, the African marble of the lionesses, and the basalt of the fountain. This choice echoes the very identity of Agde: a city founded by the Greeks over 2,500 years ago, but whose heritage is deeply marked by volcanic rocks from Agde's volcanism.

The panorama that unfolds before you is the legacy of intense volcanic activity. Several edifices were built in this same area: Mont Saint-Loup, to the northeast, today the highest (113 m), whose first eruptions date back to about 950,000 years ago; Mont Saint-Martin, to the south, which today culminates at 55 m; and Petit Pioch, to the east, whose cone probably reached nearly 80 m before being heavily scarred by the exploitation of pozzolana. These three reliefs correspond to three distinct Strombolian cones, and not to the eroded fragments of a single large volcano. With two other emission points, they belonged to a larger volcanic complex forming a maar. Volcanic activity continued for about 50,000 years, before ending with the last eruptions of Petit Pioch.

Imposing fountain in the center of the town of Agde, featuring animals, wild beasts, and amphibians, ceaselessly vomiting jets of a moving wave. Above them, a powerful woman, the beautiful Agathoise who gives her name to this monument, looks ahead with a resolute air. The scepter in her hand acts as a shepherd's crook. At the feet of the Agathoise, human figures ceaselessly spread their scented water.

No access in all directions. Lake partially visible here and there. A few nice paths and trails in the area, but nothing else. Not really recommended.

An ancient volcano located between Cap d'Agde and Agde, Mont Saint-Loup culminates at 113 meters. Dating back 750,000 years, it has shaped the landscape with islets, coves, beaches, and cliffs, while giving Agde its distinct character with monuments in iridescent grey basalt. It offers a spectacular panorama of the coastline and the hinterland from its summit, accessible by verdant trails rich in Mediterranean fauna and flora.
