Clustered around the 17th-century Benedictine Abbaye St-André, these spectacular gardens include a rose-trellis colonnade, fountains flecked with lily pads, and an olive orchard. They also offer unbeatable views over the Rhône Valley and Avignon’s skyline beyond. Fort St-André (separate entrance fee, 5.50€), founded in 1360 by Jean-le-Bon to serve as a symbol of might to the pontifical powers across the river, is adjacent to the monastery.
