I started hillwalking in the early 1970s because as soon as I got near a hill I could relax. In fact I couldn’t relax any other way. I’m not overstating this. It was a feeling that might be lost later in the walking day for any number of reasons, but for me the venue itself–the upland outdoors–acted like a tranquiliser & an antidepressant. Later in the day–whatever had happened in the interrim: you might get soaked, you might get lost, you might get blisters, you might experience a little low-wattage sublime–tiredness took over & provided another kind of chemical cosh. This never worked for me in towns & cities, or in lowlands. The built environment offered an anxious trudge, a failed yet persistent attempt at leaving yourself–or more likely the venue–behind. Exurban lowlands I just found uninteresting–I’m not saying that’s true now, & I’d rather walk on agricultural land, which I hate with a passion because it’s so clearly owned, than not walk at all. It’s the sense of ownership/not ownership, in the end, that makes the difference to me. I know rationally that I’m not “free” on access land: but at least, for the moment, no one can stop me being there.
