Large, relatively level lay-by, partly sheltered behind some trees. It was a bit noisy as it is a main road; but if I park on a road such as this, I’d not expect it to be silent anyway. Was quiet enough during the night but got busier as soon as it hit 7am. Good phone signal for O2, great links to North Wales and a petrol station about 10/15 minutes away. Beautiful stars at night!
