The beaches of La Baule and Pornichet (Loire-Atlantique) are also open. However, picnics and gatherings of more than ten people are not allowed.
It comes after decrees to open the sites were taken by local mayors and accepted by the prefects.
Access to the sea is possible for individual sport. Walking along the beach is allowed, but staying there for sunbathing is not.
In the Alpes-Maritimes, some beaches will reopen this weekend. Cannes, Nice, Antibes and Cagnes-sur-mer have notably made a request for reopening to the prefect.
The prefect of the Alpes-Maritimes, Bernard Gonzalez, declared that the reopening of the beaches will only be possible for walking or individual sports. Monitoring, social distancing and publicity measures will be put in place.
In the Pyrénées-Atlantiques, the mayors of Biarritz, Anglet, Bidart, Guéthary, Saint-Jean-de-Luz, Ciboure, Urrugne and Hendaye filed a request with the prefect to be able to reopen beaches this weekend.
They suggest reopening until 7:00 p.m. daily to avoid late gatherings for picnics or to watch the sunset. The beach would be open to surfers, people who want to swim, or who would like to walk or run.
However, staying on the beach for hours on a towel will not be allowed. The prefect is expected to announce a decision later this week.
