Caer Engan Hillfort

Stone ramparts crown a windswept hill above Caernarfon, marking where Iron Age communities made their stand over two millennia ago. Caer Engan Hillfort rewards the moderately steep climb with commanding views across Snowdonia and glimpses of defensive earthworks that once protected an entire settlement.

History buffs will appreciate the clearly visible remains - concentric stone walls that follow the hill's natural contours, plus traces of roundhouse foundations where families lived and worked. The outer defences are particularly well-preserved on the eastern approach, showing how cleverly our ancestors used the landscape to their advantage.

Expect to spend about an hour here if you're taking your time to explore and soak up the atmosphere. Families with older children who don't mind a proper walk will enjoy this, though it's not buggy-friendly and younger ones might find it all looks like 'just stones and grass'.

Access appears to be free - it's essentially open hillside with no formal facilities or interpretation boards, so bring your imagination. The site works well as part of a Caernarfon day out, perhaps before or after the castle.

Staying at one of the nearby holiday parks like Morfa Lodge or Glan Gwna puts you within easy reach of this atmospheric spot, though you'll want decent weather to make the most of both the climb and those panoramic views.
