"This lay-by is part of the 'Snow Road Scenic Route' and behind a low mound you will find a wonderful long seat from which to take in the atmosphere and the view.
This road was formerly a route for driving cattle to markets to the south and then a defensive position in WW2 (you can see the lines of anti-tank defences nearby). The bends themselves have now been 'engineered' out of the A93 much to the disappointment of classic car drivers.
With no settlement and sparse vegetation, the experience of this landscape is dominated by the landform and the weather. In driving rain, snow or mist the experience is very much of extremes, of a high and wild place where natural forces prevail. Picture those poor cattle and the drovers coming through the pass in driving sleet!"

Beside the mentioned long seat there's a wooden post on which one can put a camera to take a photo. See all the photos taken from that post at cairngorms.co.uk/photo-posts/photoposts/15/. There are no markings for parking lots, so the number in the variables is just estimated.
