Journée Grandeur Nature returns to Sartrouville this Sunday, June 15, 2025 with an edition entirely dedicated to gardens. Activities, workshops and bucolic strolls await you from 10 a.m. to 6 p.m. between the Parc du Dispensaire and the banks of the Seine. A festive open-air escapade, free of charge and full of chlorophyll for the whole family!
