Beachcombing is a relaxing activity the entire family can enjoy. Why not take the children to Plage du Rosais to see what you can spot scattered along the seashore?
When you've finished at this stretch of coastline in Le Rosais-La Flourie, why not make your way to St. Malo Citadel, St. Vincent Cathedral, and St. Malo Beach? They're not very far from Plage du Rosais and also a hit with many tourists.
