Yes, except if your shore excursion is on a Thursday as the garden is closed for visits on that day. Let your driver/guide know in the morning that you would like to include this visit and you will have the opportunity to do so while in Gassin. There are no entrance fees for the visit of this garden that was created and enhanced to become a botanical garden, classified remarkable since 2009. It shelters several hundreds of Provençal and Mediterranean species.
