Pitch your tent over by the Sapper's bothy, about 100m to the east of the summit cairn. You will get some shelter from the inevitable winds there. If you're planning on being up there in the next few weeks, you'll be sleeping on snow, so be comfortable and cosy. And be ready to change your plans; the high Cairngorms will rip apart any tent no matter how 'bombproof' the ratings have it. If it's very windy, pitch near to Lochan Buidhe or Loch Ethachan. Or in the bothy at Hutchy.
