Craig y Dinas Hillfort

Getting to Craig y Dinas requires a proper walk from Caernarfon, but the effort pays off once you're standing on the ramparts looking across North Wales. This Iron Age hillfort sits high enough to feel remote, even though civilisation isn't that far away. You're walking through what was once someone's serious fortification - multiple defensive ditches and banks that speak to genuine conflict and protection centuries ago.

The site itself is mostly earthworks now, no standing stones or ruins, so it demands a bit of imagination. But if you're interested in how ancient Welsh people lived and defended themselves, the position alone tells you plenty. The views across the Menai Strait justify the climb even if archaeology isn't your thing. Most people spend 45 minutes to an hour here, longer if you're taking photographs or just soaking it in.

History enthusiasts will find this worth the trip from Caernarfon. Families with younger kids might find it a bit underwhelming unless they're keen on scrambling about on hillsides. It's free to access - just turn up and walk. The ground can be muddy and uneven, so decent boots matter.

If you're based at any of the nearby parks - Dinlle, Aberafon, Morfa Lodge, or Gyrn Ddu - this makes a solid half-day outing. Pair it with Caernarfon Castle back in town and you've got a proper day of Welsh history sorted.
