The Réserve Naturel de Scandola takes up the promontory dividing the Balagne from the Golfe de Porto, its name derived from the ooden tiles (scandules) that cover many of the island's mountain houses. But the area's roof-like rock formations are only part of its amazing geological repertoire: its stacked slabs, towering pinnacles and gnarled claw-like outcrops were formed by Monte Cinto's volcanic eruptions 250 million years ago, and subsequent erosion has fashioned shadowy caves, grottoes and gashes in the rock. Scandola's colours are as remarkable as the shapes, the hues varying from the charcoal grey of granite to the incandescent rusty purple of porphyry.
The headland and its surrounding water were declared a nature reserve in 1975 and now support significant colonies of seabirds, dolphins and seals, as well as 450 types of seaweed and some remarkable fish such as the grouper, a species more commonly found in the Caribbean.
