In itself a beautiful cycle path with great views of the sea and salt lagoons with seabirds and flamingos. We were travelling with a children's bike trailer and had to turn back halfway. Again and again deep sandy, long pushing sections, not suitable for bike trailers with children or dogs. A great pity that the department no longer markets, maintains and adequately signs the cycle paths. We had great difficulty finding the start of the circular route near Saintes-Maries-de-la-Mer. I think if the cycle paths were better maintained and signposted with numbers and symbols, for example like in Holland where sandy sections are secured with wooden planks/boards to make them rideable, more would also be done for cycling nature lovers. Recommended for us as a family with small children only with limitations.

Lost at the end of the world, just a few steps from home! No motor vehicles for more than 20 km, almost no one this morning of November 3. The colors, the birds, the plants, these reflections on the water, this light. It's simply magical! A serenity that is more than worth the detour.

Something special - the flamingos in the Camargue. Binoculars and a camera with a good zoom lens are an advantage.

Built in 1859 to protect the Camargue from marine intrusions. Here the path goes around the Fangassier pond, a breeding ground for pink flamingos. The landscapes are magnificent and wild.
