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.

A detour to the viewing point is worthwhile! From the slightly higher vantage point, you have a better view of the scale of the saltworks. In the sunlight, you can see the pools shimmering in various shades of pink.

Attention, fellow cyclists, because this section is sometimes difficult (or not at all) to ride, but it is a magical moment between ponds, the wild Camargue as one can imagine it.
