Dinas Dinlle Hillfort

Iron Age warriors knew how to pick a spot. This clifftop hillfort sits dramatically above Caernarfon Bay, with the remains of stone ramparts still visible after two millennia. What strikes you first isn't the archaeology - it's the cracking views across to Anglesey and down the Menai Strait.

The fort itself is more about atmosphere than spectacular ruins. You'll find grassy banks and stone foundations rather than towering walls, but history buffs will appreciate the defensive layout and the sheer audacity of building here. Kids might need some imagination to picture ancient warriors, though the coastal setting keeps things interesting.

It's a proper windswept spot, so wrap up warm even in summer. The walk from the car park near Dinas Dinlle beach takes about 20 minutes uphill - nothing too strenuous but enough to earn those views. Best visited when the weather's clear; mist can roll in quickly and you'll see nothing.

Perfect for families staying at nearby sites like Dinlle Caravan Park or Morfa Lodge Holiday Park. Combine it with a beach day below or a trip into Caernarfon to see the castle. Allow an hour unless you're really into your Iron Age history, then you could happily spend longer soaking up the atmosphere and scanning the horizon where ancient lookouts once watched for raiders.
