The site is sign posted and a 5 minute walk brings you to this well preserved enclosure.
On the way through the fields check out the ruined chapel (also a CADW site).
The hut group is in a delightful woodland setting and has good information boards.
The information boards date the site back to the Iron Age. Then used throughou the Romano-British period.
There are good coastal views.
This is well worth a visit when visiting the nearby Lligwy Dolmen which is just up the road.
Some neat little drawings of the stones, in an article by W Wynn Williams called 'Early Remains at Penrhos Lligwy, Anglesey' - in Archaeologia Cambrensis v13, s3 (1867).
