The ports of Biganos have retained their wild character in a luxuriant nature. River ports well sheltered from bad weather, they are protected from winter storms.

The port of Biganos

It is the most upstream port of the Leyre and the oldest. The Eyre, commonly called La Leyre, has a configuration on the site of the Port of Biganos that makes it possible to establish a deep-water port there. This characteristic also allows the port of Biganos to be the only one in the Bassin d'Arcachon to have been established in the heart of the forest. Like the other ports in the Arcachon Bay, it is subject to tidal variations.

Historians agree that the port of Biganos is a legacy of the activity that was established nearby in the Gallo-Roman city of Boïos in the first century, as evidenced by the remains found on the site of Lamothe. There were many buildings there, the foundations of which have been discovered (fanum, chapel, warehouse and bridge). This activity continued in the Middle Ages with the construction of observation towers to guard against invasions by sea.

Its typical colorful cabins in the shade of large oak trees make it a favorite spot for nature lovers. Originally they were built with wood recovered from wrecks and with branches. Over the course of the development of the activity (in particular oyster farming) and the sedentarization of the fishermen, they were gradually rebuilt in pine. The port is built on the maritime domain and the cabins are the subject of a concession, initially reserved for professionals. As in other places in the Bassin d'Arcachon, their transformation into a dwelling was, over time, tolerated. Beyond the port activity, you can meet painters, photographers and walkers.

It houses 150 boats of all sizes which can reach the Arcachon basin after 2 kilometers of river navigation.

The port of the Tiles

The Port des Tuiles is smaller. Located further downstream, it is revealed among the reed beds and baccaris, typical vegetation of the Leyre delta; the Port des Tuiles site, with an area of ​​14 hectares, is made up of meadows with reedbeds as well as a forest of pines and pedunculate oaks. From the old wooden footbridge, now closed to the public, one could reach the Ile de Malprat on its eastern coast.

It also has its own history since it was once used to store lime-coated tiles for the collection of oyster spat. Most of the oyster farmers were supplied with tiles made in the tile factories of the town. It was also from this port that in summer, herds of cattle forded the Leyre to graze on the greasy, salty grass of the "islets" and the island of Malprat. But there are ten centuries of history in this port of Tiles, dug in the 11th century under the authority of the monks of the priory of Comprian whose religious origin goes back to Charlemagne.
