Helsbury

Helsbury Castle is an Iron Age hillfort made up of a single bank and external ditch surrounding a diameter area of approximately 140 metres. In the centre of the hillfort the foundations of a rectangular building remain which is thought to be the remains of St Syth's chapel.

Go east on a minor road from Port Isaac to Port Gaverne. Continue on the road east past St Treath to Knightsmill. Then take the road south to Treveighan. Then take the minor road east toward the B3266. The hillfort is beside a small road off the B3266 Camelford-Bodmin road. A stone stile leads onto the site.
