Ben Lomond is 974m high and you start from not much above sea level.
At first the weather was fine, with mist drifting over the hills. But soon it deteriorated and began to rain, getting harder every minute. What a nuisance it is, having to put on waterproofs. My waterproof jacket is too narrow to zip up over my camera and GPS, and the waterproof trousers are a struggle to get on without taking my boots off. Of course, as soon as I had put them on, the rain became less. Soon the clouds turned back to mist, drifting away across the loch.
Suddenly the sun burst through the clouds overhead, so I hurried up to the summit again in the hope of seeing a Brocken spectre.
I was in luck.
The only other person still on the summit to share it with me was someone for whom Ben Lomond was his first Munro (hill of over 914m), and it was quite a celebration to see such an unusual phenomenon.
The descent continued to be a mixture of sunshine and showers.
