I was up there last week when looking for chamber cairns near Alness, did Carn Liath beside Evanton, then parked at Millcraig to visit it's chamber cairn to the south with Croiche to the north. Pretty hard to find but thankfully dry(ish)! Fortunately the Mad Man Of Glass had his camera with him, as I'd been daft and left my one on the kitchen table. You'll have plenty of sites to visit up there, I'll be back up, because it isn't far away from Turriff, during the Christmas holidays.
