Hi Diane,
We have two dates in September.
On the 5th Sept date we currently have 8 booked with ages from late 40s to early-80s
On the 12th Sept date we currently have 12 booked with ages from mid-40s to early-70s
The "walking on rough ground, gradients and steps" for this tour refers to cobbled areas, steps getting in to and out of churches and some standing around. For guidance it has been suggested that if you are pretty fit, and are able to walk 500m you should be fine. I'm sure some of our other members would be able to share their experiences with you too.
Kindest regards,
Julia
