Where is Hidden filmed? The Craith Series Filming Locations Guide

Posted by Ra Moon

From the creators of Hinterland, Hidden is a crime thriller from BBC Wales and S4C. The series was filmed back-to-back in English and Welsh and has the title of Craith for Welsh audiences.

Now back for season three, Hidden was filmed in North Wales, including the beautiful landscapes of Snowdonia.

Hidden filming locations

The series starts when the body of a young girl is found in a river. Detective DI Cadi John, played by Sian Reese-Williams (Emmerdale), will have to solve the mystery murder, teaming up with Sion Alun Davies (Hinterland, Endeavour) as sergeant Owen Vaughan.

Location manager Paul Davies commented to the local newspaper Daily Post that the crew tried to show off the region as much as possible.

Here is our spoiler-free guide to the filming locations of Craith.

Where was Craith filmed
Detective inspector Cadi John lives on a small island called Ynys Castell, located in the strait which separates Anglesey from the rest of Wales.

It's connected to the mainland by a causeway only passable when the tide is out.

Snowdonia landscapes and roads
The breathtaking (and cloudy) scenery of Snowdonia National Park essentially becomes another character in Hidden.

The You Should Have Left house from the 2020 movie with Kevin Bacon was also filmed in the Welsh countryside, just a few miles away from this awesome landmark.

  1. The viaduct is Cefn Viaduct on the outskirts of Merthyr Tydfil

    1. The first viaduct you see 6 minutes in is Pontsarn viaduct in Merthyr Tydfil with Morlais castle and sanatorium hill in the background.

    2. I knew it was. Should have used my better judgement. Years of walking the Taff Trail up into Vaynor should have taught me better!

  2. The cafe is the Eric Jones Cafe outside tremadoc and beddgelet on the A498

  3. If those are shots from the series for Snowdonia - it's the bottom end of Llyn Ogwen in Cwm Ogwen methinks.

  4. Where's the police station exterior shot....???

    1. It is part of Bangor Uni.(Computer Science Dept). Dean Street.

    2. No, I am wrong about that.

    3. It is (was) at the rear of what had been the BBC office building Ty Oldfield, across the road from BBC Cardiff in Llandaff. I sometimes did training courses there & spent coffee breaks in that yard, so weird to see it on TV.

  5. it is part of Bangor Uni. Dean street.

  6. The garage which they used is in abercrave south wales

    1. I moved to Abercrave a year ago and I was convinced that was the garage.

  7. Is there already information about season 2 available?

  8. Where is the Stunning library interior shown in episode 2?
    All the exterior scenes are gorgeous and noteworthy, but the woodwork in that library is worthy of a very long trip!!
