I visited this in 1997, just as it was closing, and there was nobody there. A very eerie and atmospheric walk around this amazing area, just before sunset. The Castellu (Castle) of granite, is quite stunning. Corsica is truly 'God's country'.
As you say, Nicola, "...so beautiful, its hard to describe".
