Save money by booking a combined ticket for both the Eden Project and The Lost Gardens of Heligan. The ticket does not mean you have to visit both attractions on the same day.When booking your tickets you must select the start date of a 28-day period during which you will visit each garden for a single day. You must buy these tickets at least one day before your first visit to one of the attractions (ie by midnight on the day before your visit). Once you’ve bought the tickets, you cannot change the 28-day period that you’ve specified.Please note that family admission to the Eden is valid for two adults and two children, whereas family admission for The Lost Gardens of Heligan is valid for two adults and three children.
