The botanical garden - A small park, in the park of the archipelago, is of about 10.000 sqm, 200 m from the sea, with over 700 varieties of autochthonous and exotic plants. Citruses, bananas, palms, all kinds of fruit plants, and many flowering plants. There is also a suggestive cave, formed by enormous granite rocks lying one on top of the other, forming a "Fairies Chimney"; in the area surrounding the cave, it is also possible to see the remains of some ferrous materials used there for fusion by the Etruscans. Two streams run there, taking water to the many small springs on the slopes of Mount Capanne (1019 m). The streams are crossed by a number of little wooden bridges at the sides of which a typically native, hydrophila and tropical flora grows,: Alocasias, taros, gunneras, Ethiopian callas and palustrines, alders, forget-me-nots, enormous mounds of hydrangeas and various types of ferns, amongst which the "Osmunda regalis", a protected plant. There are also: a corner of Mediterranean maquis, where sometimes there are mushrooms, a small pine forest and even a corner of tropical forest with lianas for climbing up as far as 20 metres high. In this small paradise live and thrive: the marten cat, the hedgehog, the green lizard, the gecko, the coluber, the blind-worm, the natrix, the lizard, frogs, tortoises, eels, the Sardinian tree-toad and the gold fish. There are also birds such as the turtle-dove, the sparrow, the blackbird, the fly catcher, the great tit, the swallow, the goldfinch, the chaffinch, the cuckoo, the hoopoe, the thrush, the robin, the woodcock, the little owl, the owl, the wag-tail, the greenfinch, the blackcap and the nightingale which sings its melodious songs until late in the night and at the first light of day. There are birds just passing through as well, which, in the spring, make a stop on the island. The garden in whichI would have liked to hide when I was little - "At the Hotel Cernia Isola Botanica there is a very special garden, with two streams and many, many plants, even exotic ones. Great granite boulders rise up on its terraces. Its many, characteristic corners, its little bridges, the boulders you can climb on, the tree-house, the pond with water hyacinths, the trees with the lianas, the tropical plants with enormous leaves, make it a paradise for children. But I believe that a lot of adults, too, would like to go back to being younger to be able to hide in amongst the bamboo and the leaves as big as elephants ears."
