A low-slung rubber dinghy runs a white comb along the northwest Sardinian coast and the cliffs of Capo Marrargiu rise like an ancient wall, blackened by old lava and carved by salt. In the morning light the sea blinks and the guides point out a griffon vulture riding a thermal, wings spread against the volcanic escarpments.
