Have only done this in winter, a great hill with awesome views. Very accessible from Glenmore Lodge.
Best route: From Glenmore, walk out to the Ryvoan bothy and take the path up Meall a Buachaille. Excellent views of Loch Morlich and the Cairngorm massif to the south. You can then continue north west along the Kincardine ridge, taking in Creagan Gorm (732m) and finally Craiggowrie from where a path descends into the forest to join the forestry road which brings you out at Badaguish Centre, continue south east to return to Glenmore Lodge.
