Agde sits where the Hérault river meets the Mediterranean, a city built from dark basalt quarried from an extinct volcano.
The Canal du Midi ends its run here, and some thirty-four kilometres of cycle paths follow the towpaths past the round lock (l'écluse ronde) and out toward the Thau lagoon. This is coastal French cycling at its flattest and most contemplative: pine-shaded canal banks, flamingos in the Bagnas nature reserve, an oyster stop at Marseillan or Bouzigues along the way.
The closest thing to a climb is Mont Saint-Loup, a 113-metre basalt cone on the edge of Cap d'Agde, its looping path better suited to a recovery spin than an attack. For real gradient, riders continue along the coast to Sète and Mont Saint-Clair, the sailors' hill above the lagoon with its wide Mediterranean panorama. Agde rewards those who come for rhythm over suffering — long, level kilometres, sea air, and a black-stone skyline at the finish.
