A quiet road.....generally. Any traffic is slow moving. Grab an ice cream at the Llangower Railway Station.

Maybe not a permanent fixture, but half a dozen gentle cattle, with their wonderfully hairy faces, glowing in this magnificent September sun.

Don't go too far if it's rained or you end up getting your feet wet. Beautiful place not far from car park and cafe can be quite stoney

Good little cafe on Bala Lake it was an old fashioned van outside that has lots of different flavors of ice cream. It was blasting out old 60s music which was fun. Dogs only outside under the umbrellas on hot days. Try the cheese & ham toastie. Prices are a little high but it's well worth it.
