Sorry for getting back late.
I drove up from Swansea, asking Tomtom not to use any Motorways.
The drive from Swansea to Betws-Y-Coed should have been just about 4 hours, but I took it in close to 8 hours which is what I planned; stoppingat a number of picturesque points to shoot the odd photo.
Stayed at the Royal Oak in Betws-Y-Coed, a wonderful hotel.
The next day, I did a drive along the A5, from Betws-Y-Coed towards Capel Curing, there is the Swallows Falls. Then along the A4086 going into the A498 to Beddgelert. From there took the A4085 to Caernafron (where there is a nice castle, and Caernafron is a nice village to see too). Had lunch in Caernafron, then drove along the A487 towards Bangor then took the A5 back to Capel Curing and heading to the hotel in Betws-Y-Coed .
This whole drive is no more than 2 hours, going 10% below the speed limit. However, it took me the best part of 12 hours as I stopped in way too many picturesque locations (as has been indicated earlier, there are far too many).
As a matter of fact, I had to mentally keep telling myself that, in my lifetime, there is no way I can shoot all the wonderful scenes that I get to see, and I have to "let go" of too many. You will just have to choose the ones you like.
I wanted to go up Snowdon, but it wasn't advised at the time I was there. It was -5 in the day-time in any of the villages, frost was everywhere. Even the Swallow falls were closed to the public, but because of a notice saying "go at your own risk", I took the risk and went in.
In total, spent two night there, could have spent 2 life-times and wouldn't get bored.
