This is a moderate walk with a long steep climb. There are no toilets or pubs, except in Usk itself.

Leave the town square by the south-east corner and proceed along Four Ash Street. Pass the former Greyhound Inn (now a house) and continue on Chepstow Road. Turn right at The Olway Inn Hotel (formerly Casey's Court) and go up the steep hill.

Continue along the lane, crossing above the dual carriageway. At the crossroads (where the Flood Route is signposted in other directions), go straight up the narrow lane. After about 150 metres ignore the parallel track on the right, which goes to a house.

At "Graig-Yr-Ieir" house (the white house at the end of the lane), take the narrow, muddy track up the hill through Mardy Hill Wood. At the top follow the track with a field to the left and a hedge to the right. When visibility is good, there are splendid views from here across to the hills surrounding Abergavenny. (If a small dog follows you from the first house on the right, take it back immediately or otherwise it might follow you for miles!)

Llewelyn's Dingle

Shortly after the next house on the left, follow the track round to the right. In the hamlet of Coed Cwnwr take the road to the right (where there is a postbox.)

Follow this down the beautiful valley called Llewelyn's Dingle. Turn right at the T-junction and go under the dual carriageway.

Opposite St Llywel's Church in Llanllowell, take the lane on the right (signposted Usk Flood Route). Follow this for 1 mile and turn left at the crossroads (signposted Usk Flood Route).

Follow this to the T-junction by The Olway Inn Hotel and turn left. Follow the road back to the town square.
