In reply to mike123:
You're right from what I know. Lecht and Glencoe have snow machines and beginner slopes open but no lifts. Cairngorm is down to linking patches in the Ciste.
If you're on FB then Glencoe, Lecht and Cairngorm ski areas all have up dates. Also lots of web cams for those areas.
Again on FB are various groups: backcountry UK, Ground conditions UK and ground conditions Scottish mountains. All good for asking q's and getting gup to date info.
