Cwm Crawnon Road (B4558)
Running parallel to the River Usk, the B4558 is a tranquil, winding path through the valley floor. It is primarily a route for taking in the lush green surroundings rather than testing your line-choice, with a gentle rhythm that suits older classics and relaxed modern cruisers alike.
The proximity of the canal towpath means you'll frequently encounter walkers on the narrower stretches near the villages.
