The Jardin Botanique Exotique du Val Rahmeh, run by the Natural History Museum of Paris, is one of the finest botanical gardens on the Riviera. Menton's frost-free winters allow plants to thrive here that would not survive anywhere else in France — the garden contains species from sub-Saharan Africa, Asia, and the Americas alongside Mediterranean standards.
The terraced grounds, about 11,000 square metres in all, climb up a hillside in the Garavan quarter east of the centre. In spring the garden is spectacular; in summer the shade and the sound of water make it a refuge from the heat along the coast. Allow a couple of hours.
