An often-shot location, but on mornings like this it's clear why. This beautifully curved silver birch tree, known as the lonely tree, is perched on a pile of slate chippings and there's various compositions you can make of it snaking through and around the Pen-y-pass in the background. 

It was an incredibly gusty morning, so the water wasn't anything like smooth, but I think the surface picks out the reflected colours in the sky.
