Built in 1854 at a time when Paimboeuf was the advanced port of Nantes, before being replaced by Saint-Nazaire. It is the only lighthouse on the Loire and the most "land-based" in France because it is 10 km from the ocean.

This former, very active fishing and barge unloading port probably takes its name from the colour of the shutters of the house right next door. Departure of the coastal path towards Saint-Brévin. Toilets.

I, who am not very comfortable in gusts of wind, admit that I have not yet dared to take the plunge.

A nice and welcoming café, often open when others are closed. View of the Loire!

It takes a bit of courage to ride up there next to the roaring traffic when you're standing in front of the huge bridge. A cyclist coming towards me rang my bell - we said hello - and off we went. I prayed not to get a flat tire on this bridge - everything went well. There is no alternative to crossing the Loire at this point. But I'm still not sure whether there was a sign below prohibiting pedestrians and cyclists 🧐

Unfortunately we didn't see it when we arrived (30.8.24) in the rain. The next day, when it was humid and dry, we were able to marvel at this enormous animal.

Departure point for the free bus transfer in Saint-Brevin-des-Pins. In July and August, a bus with a bike trailer crosses the bridge every hour. It is not recommended to cross the bridge with a bike, particularly because of the crosswinds.
