In reply to Euan Todd:
I walked in to do Sron na Lairig today. There's very little snow on the route, but the turf is well frozen. I assume it goes in these conditions, but I decided to explore the coire instead and head over the summit from there. There's a bit of fun to be had on some small icefalls on the way up.The Beinn Fhada ridge was totally bare.
The path in was lethal, about half of it is pure ice, easier to walk the tussocks instead.
