This was forecast to be the worst day of the week for rubbish weather, they were not wrong. However there is no such thing as bad weather only inappropriate clothing. I was to find out my over trousers were inappropriate!!
The walk was almost wholly in rain either drizzle or full on but we girded our loins and went for it.

We parked at the road end in Dinorwig and followed signs for the Slate Trail which as described took us through the huge but abandoned slate quarries. The views down to Llyn Peris , Llyn Padarn and the mountains beyond were partly obscured by the mist, but no doubt worth taking this route on a good day.

Must be the wet weather.

We were also walking above the Dinorwig Power Station.
We descended down the zig zags to the southern end of Llyn Peris and then walked along the road north west to have lunch near Dolbadarn Castle.

The walk towards the country park passed the National Slate Museum which as it had free entry in we went. There were lots of interesting photos and old machinery, clearly they were hard characters to work the mines.Click this link

I know that face.
There are a number of colour coded walks through the wooded park and we followed the yellow path to the end of the woods and then struck uphill back to the car.
And so the end of our week in Snowdonia and considering the past weather we were pretty fortunate.
