The long abandoned Barracks and Mill buildings of Rhosydd Quarry in the Moelwyn mountains of North Wales on a changeable day last September. A break in the heavy cloud allowed a burst of sunlight through that lit up the shiny slate rubble to make it look a bit like water. The dark buildings stood out against the lower slopes of Foel Ddu.

The spartan barracks at Rhosydd, a hard place to live and work, not far from the summit of a mountain.

Great walk through a variety of tree species and easy to follow path. Would recommend going anti clockwise/reverse of suggested route as scenery coming back through gorge is stunning (with the bridge as a nice suprise at the end) and easier downhill as plenty of small steps. If taking a dog then be aware there is/are sheep grazing along the route but no stiles or fences to climb if you have a large dog but there are very steep banks/drops along the gorge so recommend keeping on a lead if they are a bit hectic! Would not recommend unless you have a basic level of fitness as some parts of the path are extremely steep.

Slate was mined here above and below ground from about 1830. The remote location proved difficult, and a series of financial troubles hampered the quarry. It shut during WW1 and reopened afterwards until finally closing in 1948. At it's peak, this was the second-largest underground slate mine in North Wales. Today you can explore the spoil and some of the old machinery.

This remote and ethereal ancient oak woodland was once part of a historic estate and slopes gently towards Llyn Mair (Mary's Lake). A network of trails offers spectacular views across Snowdonia National Park, while steam trains from the iconic Ffestiniog Railway wind along the border. With rare wildlife and an abundance of beautiful flora, Coed Hafod y Llyn is the perfect forest destination for train enthusiasts and nature lovers. (Woodland Trust)

How much poorer would European literature be if he didn't exist: MERLIN (according to Wikipedia, the Welsh name originates from Myrddin or Merddin) is one of the biggest stars in the sky of mythology. Together with the heroic King Arthur, he has conquered a permanent place in the collective memory of people - at least in the fantasy world of countless authors who have told his story over and over again for centuries, and above all in their ever-fascinating readers or listeners. I don't know exactly what connection this hiking highlight with the beautiful name "Merlin's Pool" has with him. But the main thing is: the myth lives on!
