The single lock of Portiragnes opens onto the Agde reach downstream. It is a typical area of the landscapes of the Languedoc coastal strip. Indeed, from this lock, the surface of the canal is at an altitude of only 1 meter above sea level. It runs alongside wetlands of former salt ponds (la grande Maïre), where we find rich fauna and flora (bulls, horses, waders, amphibians, reeds...) and some pine groves. These places are conducive to the establishment of numerous campsites.

The round lock of Agde is the most original on the canal. Built in 1675-1676. It was put into operation in 1678 when the canal from Béziers to the Étang de Thau was opened to navigation. A particular situation, an original response: it was decided to build a round lock with three gates. The first opens towards the city of Sète and the Étang de Thau via a short passage on the Hérault; the second opens onto the canal coming from Béziers; the third opens onto the small canal which allows small boats to reach the city of Agde and its maritime port and then Grau d'Agde. The round lock was commissioned in 1678 when navigation opened between the Étang de Thau and Béziers. It originally measured 30 meters in diameter with a depth of 5.20 meters in the center. Thanks to this round lock and the low canal, small maritime boats can come onto the canal!

"A 240.129 km long, 2.25 to 2.50 m deep waterway was declared a cultural monument as a "bridge" between the Mediterranean and the Atlantic with 328 structures such as bridges - such as the canal bridge over the Orb -, locks - such as the 7 lock cascades of Fonserrannes -, tunnels, aqueducts and 49 canals over streams and rivers." says the documentary from "Treasures of the World - Heritage of Humanity", a television series that brings culture-loving viewers closer to world cultural heritage sites with short film contributions (in German). The episode about the CANAL DU MIDI is available in the ARD media library under this link: => https://www.ardmediathek.de/video/schaetze-der-welt/gcanal-du-midi-frankreich-folge-224/swr/Y3JpZDovL3N3ci5kZS82OTg2NDg2

It is not advisable to take the barge with a heavy e-bike. It is very steep and there are steps into the boat.

The Libron works are an ingenious system of locks dating from 1855 and which allow the Canal du Midi to cross the Libron without suffering the problems linked to the periodic flooding of the river.
