At the entrance to the Loire estuary, the landscape is in constant motion. Ships sail in and out of the river, gliding along with the tides. Their names evoke distant horizons, sometimes from other continents, and remind us that Saint-Nazaire has always been a gateway to the open sea.

As the leading port on France's Atlantic seaboard, the Grand Port Maritime de Nantes - Saint-Nazaire plays a major role in the regional and national economy. Its facilities cover almost 2,700 hectares between Saint-Nazaire and Nantes, and welcome some 3,000 ships every year. A vast, structured port territory, where shipping, industry, energy and logistics meet.

A guided tour will give you the full picture. Aboard a bus, the route skirts the quays, basins and terminals, punctuated by stops and descents to observe the infrastructure at close quarters. You'll see the various port activities, the loading and unloading zones, and the industrial landscapes that punctuate the estuary's shores.

The tour extends from the docks at Saint-Nazaire to the Donges refinery, providing a comprehensive overview of the port and its organization. The guide sheds light on the economic, logistical and territorial issues at stake, rendering legible a whole often perceived as inaccessible or complex.

During the summer months, you can also discover the port from the water. Discovery cruises allow visitors to approach the port from the estuary, offering a different perspective on the facilities and the constant dialogue between the river, the ocean and human activities.

Tours last around two hours and must be booked in advance. Identification is required on the day of the visit, reminding visitors that they are entering a living, strategic site.

This exploration of the port is the perfect complement to a stay in Pornichet. It sheds a striking light on the maritime and industrial dimension of the area, and provides a better understanding of the close links between the river, the ocean and the exchanges that shape the region.
