Dazza, I use photobucket as the hosting site, so can post as many as I want.
The castle on the cliff top is Carreg Cennan, at the western end of the Brecon Beacons. The bridge is the Menai suspension bridge, seen from Anglesey. The 2nd castle is Beaumaris on Anglesey.
The highest pass in Wales is one I was tipped off to - turn off the A470 at Dinas Mawddwy, just south of Dolgellau. The road goes over the pass and brings you out near Bala. Only a single track road, no good for speed merchants, but great for scenery and peace and quiet.
The photo of my bike near the sharp bend with mountain range in the background is the B4391. Turn off the A4212 halfway along, between Bala and Trawsfynydd, and it takes you to Ffestiniog. A brilliant road that twists and winds it's way over and around the hills in the middle of nowhere. Quiet, empty, good surface (ish). No one up there.
I love roads like the 483 to Newtown, but if I stuck to those, I'd pretty soon lose my license, so I head for the mountain roads more now. No police, no traffic, and great scenery. I tried some new ones this time; some were good, others just turned out to be very narrow country tracks, bumpy, hemmed in by trees and hedges. Still a few more to explore yet
