I started with the cubs, when we were living in Germany back in the early 80's. My dad was a soldier and we were posted there. The army used to organise a march/walk, and the cubs, scouts, brownies and guides from various camps used to take part in it as well as teams of soldiers from various regiments. It was called the Rheindahlen Allied March (if my memory serves me well), and it was a road walk. I can't remember the exact distance, but I think it was around 20km. I took part in the walk twice, and got a medal for it each time. I was 8yrs old on the first walk, and the walking bug took me from then.
We used to go on walks with my mum and dad in various places around Germany, there were two that stood out for me - the Moselle/ Rhein Valleys, and the Black forest. I used to love walking in forests, and still do. When we came back to England, after my dad died, I used to go to the Lake District a lot with a friend, who had an aunty living just outside Kendal, so we got plenty of walking in then.
