When I was a bit younger I used to get up at about five in the morning or earlier and drive down to Silbury Hill – the tallest prehistoric man-made mound in Europe – from London and climb to the top in time to see dawn breaking.
Another favourite spot is Maiden Castle in Dorset – the largest and most complex Iron Age hill fort in Britain, which has the most fantastic earthworks.
The views from both are amazing. Plus, I've always been fascinated by these ancient sites and sometimes, when I was restless and depressed as a younger man, I would find going up them quite inspirational. Often I'd be the only person around.
