Awesome road over the mountain - watch out for the Welsh ARmy training if the red flag is out
An utterly brilliant biking road, BUT one of the main caravan routes to the Welsh Coast. Go when it's quiet or you'll be frustrated to hell. Basically, Shrewsbury to Welshpool is fast open sweepers, Welshpool to Mallwyd is a fabulous mix of high-speed corners and some fast straights, and Mallwyd to Dolgellau is mountainous with spectacular scenery. If refreshments are required, Welshpool is really the only settlement of note on the whole run.
