Beachcombing is a relaxing activity the whole family can get into. So, why not take the children to Plage de la Touesse to see what you can spot washed up on the seashore?
When you've finished at this stretch of coastline in Saint-Coulomb, why not check out St. Malo Citadel, St. Vincent Cathedral, and St. Malo Beach? They're not too far from Plage de la Touesse and also a hit with many travelers.
