Open Gardens/Jardins Ouverts is a registered association (no.W232001865), which encourages owners to open their gardens to the public.
Admission is by a Day Pass (5 €) bought at the gate allowing access to that, and any garden open nearby on that day.
An Annual Membership Card (10 €) entitles you to visit any of the gardens throughout the year on their stated open days.

The association is also linked to several Partner Gardens, some of whom are Jardins Remarquable or similar, who help support them in numerous ways.
The proceeds are donated to charitable organizations in France. Please go the website
