Mount Castellaro is one of the most fascinating points of the Natural Park’s coastline: an uphill field of scotch broom that ends with a vertical cliff descending into the sea. On the highest point of the mountain, just behind the cliff, a cross 8 meters high was erected in 1902. From 1998 to 2015, on this mountain the Park Authority set up an observation post to monitor the spring migration of the birds of prey populating this area, which saw the participation of numerous volunteers from all over Italy and Europe. In the span of time monitored in the study, more than 46 thousand raptors were observed, belonging to 26 different species, including the European honey buzzard, the Western marsh harrier and the kestrel.
