Going Underground: A 4,000-Year Journey at the Great Orme Mines

We all need a "detox" from the news cycle occasionally, and last week, we found the perfect place to do it—about 200 feet underground.
While the rest of the country was focused on the Senedd polls, we hopped in the truck for the scenic 50-minute drive from Emlyn’s Coppice to Llandudno. Our destination? A place that, incredibly, we only properly discovered a year or so ago: The Great Orme Bronze Age Mines.
Mind-Blowing Ancient Engineering
I’ll be honest, I thought I knew what to expect, but the sheer scale of this place is staggering. It is officially the largest prehistoric copper mine ever discovered.
Think about that for a second. Right here in North Wales, 4,000 years ago, people were running a sophisticated international business. They weren't just digging holes; they were using animal fat candles to light their way and managing a trade network that stretched as far as the Baltic and France. They even traded with Cornwall to acquire the tin needed to turn their copper into bronze. We think of ancient history as quite basic, but these people had incredibly sophisticated processes.

The "Tall Person" Struggle
Being over 6ft, I quickly learned two things: the Bronze Age miners were significantly shorter than me, and a safety helmet adds an "invisible" two inches to your height that your brain forgets to account for!
I spent a fair amount of the tunnel walk ducking and occasionally testing the structural integrity of my helmet against the rock. Every single inch of these tunnels was hand-dug using nothing but bone and stone tools—mostly antler picks and stone hammers. It’s not a natural cave system; it’s a man-made monument to human grit.
A few practical tips for your visit:
The Temperature: It’s a constant 5-8°C down there. Even if it’s a scorcher on the beach, bring a light coat.
The Floors: They’ve lined the paths with grippy concrete, but it’s still a "wet" mine and could be slippery on the slopes in smooth soles. Wear sturdy shoes!
The Heights: If you aren’t a fan of heights, be prepared for the floor grates. They cross sections up to 25 meters deep (and there's even a Victorian shaft that drops a dizzying 145 meters!). My wife had to do the "fast-walk" over those, but the view into the depths is incredible.
Making a Day of It: Trams & Treats
The drive up the Great Orme is spectacular—honestly, the views are so good it almost feels illegal to be driving there! There is plenty of parking right at the mine.

However, if you want the full experience, the Great Orme Tramway has a halfway station just below the mine gates. It’s the perfect way to arrive in style.
After we emerged back into the 21st century, we headed into Llandudno for a bit of a "wind-down" at Botanical Babe—half plant shop, half cafe. The coffee was excellent, and the cakes were exactly what we needed before a stroll along the North Shore.
💡 Did You Know?
The Name: "Great Orme" comes from the Old Norse word Orm, meaning Sea Serpent. Viking explorers thought the headland looked like a monster rising from the waves.
Child Miners: Some tunnels are so narrow that historians believe they could only have been excavated by children as young as five.
Bone Tools: Archaeologists have found over 30,000 bone fragments used as tools on-site.
The Rediscovery: The mines were "hidden" for millennia until 1987, when the site was being surveyed for a car park!
Global Reach: Copper from this specific mine has been found in Bronze Age axes across Europe.

What really made the trip was the team at the mines. Many of them have been there since the site was first rediscovered in the 80s. Their passion is infectious, and they are a true "mine" of information.
Planning a stay at the Coppice soon? Make sure to add this to your itinerary. Just remember to duck!
