We have often driven down the A30,  and wondered what is on the hill to the north of us, as we pass Goss Moor, haunted with memories of its horrendous traffic jams.

The answer is Castle an Dinas, one of the largest Iron Age hillforts in Cornwall. It is a superb site, with stunning views ranging from Rough Tor and Brown Willy in the east, Hensbarrow to the south, St Agnes beacon to the west, and glimpses of the sea to the north. This is one of the few places where the term ‘360 degree view’ is completely valid.
