I am 71 - and I was disabled for five years - so I do appreciate being able to walk.
I can see this hill from my house - and I always wanted to walk to the top from my house.
There is an annual charity walk to the top (cancelled this year) - but the walk goes over private land - so you cannot walk to the top at any other time... but you can walk around it, as I did today.
14km, 8.6 miles, 225 metres height gain in four hours moving, five hours elapsed. 1,155 "active" calories burnt! A few days ago I took a bus to the halfway point and walked back.
