As Broen says try and make time to see the hut circles. It’s a good starting place to walk up to the Caer y Tawr hillfort.
The site is well signposted from the road to the South Stack. There are around 20 ‘huts’ left to be seen at the foot of Holyhead Mountain dating back to the Iron Age.
Some of the huts look to have stone benches and bowls.
