Penmachno roman bridge near Betws-y-coed in Snowdonia National Park. With the autumn colours looking great this year, after a sunrise at Llyn Padarn in Llanberis, I decided to have a drive to Penmachno and capture this wonderful 16th century packhorse bridge in full autumn colours. It's one of the hidden gems of the Snowdonia National Park, it's well worth a drive further down the Penmachno valley too as it's a great place to escape the hustle and bustle of the main hotspots.
