It is 40 km, about 5 hrs. Start at Keiloch car park, head up the Dee to Inverquoich, cross the bridge at the Devil’s Punchbowl, then up Glenquoich. After a few miles you will cross the Quoich again and Beinn a Bhruid is in front of you. Follow the track and, you then have an 800m climb that just goes on and on. The path becomes indistinct on the top, but head for North Top and then head East. Go to the right of a small hill, then down into the Snek, careful here it is very steep and loose. The path from here starts rough and rocky but further on is smooth with drainage ditches – follow this all the way back to Keiloch via Invercauld.
