This is ideal for young families and older people alike. It's on tarmac lanes and farm tracks and offers some great views over the Usk Valley above Crickhowell. It is short and can be a great walk before the kids go to bed, or to get the appetite going before a meal.
Starting from the pay and display car park (at Grid Reference SO218185) exit the car park into Standard Street and turn left down to Beaufort St. Turn right, go passed the Bear Hotel and on passed the petrol station. Turn right up Llanbedr Road and walk for several hundred yards where you will turn left into Oakfield Drive. After about 200 yards turn right up Darren View.
At the top of the road it bends round to the left. Follow the road and continue on the flat until the road stops. On your right there is a large 5 bar gate onto a sunken lane. Turn left along the lane and down the hill. It goes over a bridge across the Cwmbeth brook and meets Pregge Lane. At the T junction with Pregge Lane turn right up the hill. The first hundred yards or so are steep, but it soon evens out into a gentle walk up the quiet lane which leads up to Gwernvale Farm.
Beware, the OS map (OL13) has labelled the farm as a hotel, which it is not. Go through the gate across the lane and into the large yard with stock sheds on the right and to the left you will see a lane continuing up through another gate. Go through the gate and enjoy the walk following the lane as it goes up towards Twyn. The lane climbs steadily up to a further gate. You can stop and turn around having paused and enjoyed the views from the lane just below the gate, out across the Usk Valley. Return to Crickhowell by retracing your steps.
