A huge variety of succulent plants distributed along a path scattered with stairs, bridges and paths along which suddenly open panoramic views of the Monegasque coast. All magnificently kept both from a strictly botanical point of view and for decoration and cleanliness. This, in short, is what the Jardin Exotique of Monte Carlo has offered since 1933. And then, in reality, it is not finished here, since there is also the splendid Grotte de l’Observatoire, a ravine about 100 metres above sea level rich in stalactites, stalagmites and other concretions. In this cave, moreover, numerous finds have been found attesting the presence of man already in prehistoric times, all catalogued in the Anthropological Museum inside the garden.
