This walk to see the Cwmorthin waterfalls and quarry is a great short walk for when you don’t have too long but aren’t ready to go home yet. You could spend as long or as little as you like exploring here and ‘bad’ weather doesn’t really take anything away from it so it’s a good option for a rainy day walk.

What to expect

Although it’s a short route, the path is very loose and can be slippery in sections, there are also big drops by the waterfall so not the safest walk for young children or dogs.

We arrived here on a midweek evening so had no trouble getting parked up but we have heard it can be very different during busy times, the car park isn’t massive and the road up towards it is very steep and narrow.

The route

  • 1.5 Miles
  • 1-2 Hours
  • Easy–Moderate

Simply head up the main path through the quarry and explore the bits you see, the waterfalls, abandoned buildings, disused mines and the lake at the top.

Highlights on the way
  • Cwmorthin Abandoned Buildings
  • Cwmorthin Waterfalls

Step-by-step

  1. From the car park, head left and take the first footage on your left, this will take you to the first waterfall.
  2. After this, come back on yourself slightly to rejoin the main path upto and into the quarry.
  3. Follow this until you get to the ruins, you can explore these now or leave them until the way back like we did.
  4. Further up the main path, you'll see a path that leads off to the right towards a mine entrance - it's kept closed as this is the entrance to 'The Deep Sleep' Hotel.
  5. Check out the lake and while you're up here before heading back down to the car park.

Tips & what to bring

A head torch might come in handy if you find any disused mines but other than that, just sensible footwear and clothing. Always remember that quarries can be dangerous so keep yourself safe, there’s loose slate and disused metal workings across the site that can fall on you or you can trip over.
