Hi Lizzy
I can confirm the Walking in The Ahr Valley holiday is a very good trip, I have been on it several times, There are some photos on the Holiday snaps of it from me, Not sure what page but I think it may be page 12 or upwards. The walking is good although I would not considerate overly difficult, The Red Wine trail is a hike at gentle pace. It is worth visiting, If you would like any more info please let me know,
Regards Andy
