Famous faces from across Wales are travelling though the region as part of a 200 mile sponsored walk in aid of the Wales Air Ambulance.
Led by Welsh tenor Rhys Meirion, the third and final Cerddwn Ymlaen/Walk On Wales,started on July 5 and continues until July 12.
Rhys has raised close to £200,000 over the past two years from the highly successful walks, in which celebrities walk 200 miles across Wales’ most picturesque countryside.
Thousands of well wishers and supporters are expected to wave and cheer the walkers on as they travel through Wales.
Those walking the whole distance include TV wildlife presenter Iolo Williams, rugby legend Robin McBryde, X-Factor star Lucie Jones, BBC Wales Hinterland star Richard Harrington and Welsh comedian Tudur Owen.
The walkers will be averaging about 26 miles per day across Wales.
The walk will take eight days to complete, and with the expected heat wave set for July, the walkers will be pushed to the limits of their physical endurance.
The walk starts from Eirias Park in Colwyn Bay on Saturday, July 5, and Welsh Office minister David Jones will join them for their first five miles.
The walkers arrived in Glyn Ceiriog at about 4.30pm on Sunday, July 6 for afternoon tea at the Canolfan Ceiriog Centre before finishing in Llanarmon DC at about 6.30pm.
Today (Monday, July 7), the walkers arrived in Llanrhaeadr ym Mochnant at about 10.30am.
They will stop in the village for refreshments and will meet local wellwishers and supporters before heading on to Llanfyllin. They aim to reach Llanfyllin for about noon.
There they will be met by Town Mayor Ann Williams and will have lunch in the town, which is being organised by members of the WI and Merched y Wawr.
The walkers will spend about an hour in the town and resume their walk.
They also plan to walk through the grounds of Llanfyllin High School and Llanfyllin Primary School on their way through the town where they will be joined by pupils and teachers.
