An iron age fort in the Cornish coastal cliffs.
Not to be confused with Treryn Dinas, which is near the Minack Theatre in the South. Trereen Dinas is on the North Coast and is miles away from anwhere, but near Guarnards Head, near Zennor, right at the end (or beginning) of Cornwall. Even with the help of an ordnance survey map, we were never entirely sure we actually got there. The only places to stop nearby were private, so I jumped out the car and had a look. There was certainly a path that led the direction of a big protruding rock in the sea, and that was probably it.
So only go and visit if you have time for a walk. There was a pub nearby you could park at, but I’m guessing it’s about a half hour walk from there.
We drove along this coastal road at about 5-6pm in August and I have to say it was absolutely breathtaking. We passed a ruined tin mine that was fantastic to photograph in that sunlight, and I do wonder if it was used in the Poldark series. It was owned by The National Trust, but I’ve just looked through their handbook and I can’t find the name of it unfortunately.
The farmers and landowners in the area keep all the old field boundries – many of the stone walls surviving from the Bronze and Iron ages. There are all kinds of great looking walks to interesting shaped rocks and places to explore. So if you want to go on a walking holiday I would definitely recommend this area along the B3306.
