We went to the National Slate Museum having no idea what to expect thinking that it might be a boring little trip on a rainy day. However, we were thoroughly surprised to find this museum was a little gem. There was much to admire, firstly with the ease of accessibility to the facilities and each area of the museum was well presented and enjoyable to view. There were many interesting artifacts to observe and the history of the slate mining in the area was well documented. Our favourite parts were seeing the mining houses over time (it felt like stepping back in time) and the demonstration of the slate being cut, which was both illuminating and humerous. Definitely worth a visit, especially on a rainy day!

Amazing day out for hiking and exploring but also learning by popping into the old hospital.

The place is very interesting. Everyone is very friendly and welcoming, blacksmith, slate trimmer, guides, shop team all great. It's closing in a couple of weeks for a refurbishment. I'm sure it'll be even better when it reopens. Shop on site sells the usual attraction goodies, cafe sells cafe stuff. Little kids play area, some quarry cottages all dressed up inside. Lots of original artifacts, machines & history. Great place, get along and enjoy it.

A great place for everyone, especially the youngest, to see and understand the work people had to do and what the effects were. One of the largest slate quarry in the world, which was used by a large part of Europe. Thanks to the people working here, others had a roof over their heads. A lot of rooms showing various stages of production, devices and tools of those times. It is also worth seeing the lines of buildings from 1861 - 1901 - 1969 to compare living standards over a period of over 100 years. A great place for a trip of at least an hour.

It's Free! and you can spend a good few hours in it. You can donate in boxes and it is worth a donation. The area is beautiful as you are surrounded by the mountains and can easily make a great day out in the area. If you like outdoors, go for it on a nice day.

Great place to visit with plenty to do for up to 2 hours. Free entry was a big bonus, the museum is going to close for some essential refurb works so please check before travelling. Definitely recommend a visit.

An interesting place to visit! Entry is free which is always nice 😉 Lots of exhibits to look at, along with videos, plenty of history information and some practical demonstrations. The cottages at the end of the museum were a really nice touch, as was the viewing area for the water wheel.
