Tomen-y-mur

The walk up Tomen-y-mur from Blaenau Ffestiniog is steep and a bit relentless, but the payoff is genuine. You're climbing to a proper Iron Age hilfort - the sort of place that stops you mid-stride because you suddenly understand why someone built a fortress here 2,000 years ago. The views across Snowdonia open up as you climb, and on a clear day you can see for miles across the slate country.

It's not a casual stroll. Allow a good two hours return from the car park, more if you're not a regular walker. The path climbs through woodland first, then opens onto moorland - bring decent boots because it can be boggy, and the weather turns fast up here. Kids aged ten and up will manage it fine, but younger ones might struggle with the gradient.

What makes this worth the effort isn't just the archaeology. It's the sense of standing somewhere that actually mattered - the fort's position commands the valley, and you feel that immediately. The ramparts are still visible, humped and grassy, running across the hilltop. Bring a map; the summit's not marked obviously and mist can roll in without warning.

If you're staying at Barcdy Caravan & Camping Park or Llechwedd Glamping nearby, this fits perfectly into a Snowdonia week. It's free, takes a morning, and genuinely beats the more famous peaks for solitude. Go midweek if possible - weekends see more foot traffic than you'd expect.
