Wild swimming in Golwen quarry
Across the Mawddach estuary from Barmouth is an old slate quarry- one of the best wild swimming sites in Wales.
Take the A493 south out of Fairbourne till you see a left turn opposite a phone box.
Park up in the old telephone exchange and walk up the side road, past a few shepherds cottages, now tarted up and full of New Agers.
After half a mile go through the stile right and take the path up the hill. Where the path forks, go right and pass under a few slate bridges till you reach a plateau with an excellent view back to Barmouth.
Enter a 20 yard tunnel and, if the sun is shining, emerge into the most magical place.
The quarry if said to be 40 metres deep. The copper leached from the slate keeps the water clear. It’s cold, but a beautiful swim.

Oh my. Being from the States, I might have thought such a place existed only in some remote corner of New Zealand rather than a bike-ride distance from a Welsh village. Simply reinforces that I must visit the UK before I die! Thanks for posting the lovely pics!
No longer accessible unfortunately!
