During low tide the holes in these rocks remain filled with lukewarm water. I only saw 3 people in 2 hours.

The Lilleau des Niges nature reserve stretches from Ars-en-Ré to Portes-en-Ré. This large reserve is a refuge and shelter for many birds that nest there. For this reason it is forbidden to enter, but you can walk around it and especially by bike. From the Phare des Baleines you have a breathtaking view of the reserve.
