Perched on a rocky promontory above the sea, the Jardin Exotique de Roscoff is an unexpectedly lush garden of subtropical plants — palms, agaves, tree ferns, proteas — that thrive outdoors thanks to the Gulf Stream's warming influence. On a grey Breton day the contrast between the granite coast and the green exuberance of the garden is striking.
The garden is small but well maintained and the views from the rocks at the edge are excellent. It's run by the town and entry is inexpensive. Allow 45 minutes to an hour.
