Carningli Hillfort Inner Enclosure

The walk up Carningli is proper rewarding - you're climbing 300-odd metres to reach the inner enclosure of this Iron Age hillfort, and the effort pays off with views across Cardigan Bay that stretch for miles on a clear day. The site itself consists of stone ramparts and defensive ditches that once enclosed a settlement, though you're mostly looking at earthworks rather than dramatic ruins. On the ground, it's quite easy to miss what you're looking at unless you've got a rough sense of the fort's layout - the ramparts blend into the landscape if you're not paying attention.

Walkers will absolutely get the most out of this. The climb takes around 45 minutes from Newport, and it's steady rather than brutal, though the final push is a bit steep. History buffs will find it interesting as a classic Welsh Iron Age fortification, though there's limited interpretation on site - you'll need to do your homework beforehand if you want the full story. Families with younger kids might find the walk more engaging than the actual remains, to be honest.

It's free to visit and accessible year-round, though winter can turn it into a mud bath. Allow two to three hours total from Newport if you want to enjoy the views without rushing. Combined with a base at one of the nearby parks like Fishguard Bay Resort or Trewrach Glamping, this makes a solid addition to a Pembrokeshire walking holiday - especially if you're exploring the Preseli Hills area more broadly.
