Solo. From the start of a section of old road on A890 at NH090530. There's a locked gate so you can't drive on to the old road. Followed the track (gravel track to small hydro dam, then a rather rough track), and later on a path to Coire Crubaidh. Up to the broad NNE shoulder of Carn Breac, cutting the corner so not reaching the 435m col, and on to the summit outcrop and a short distance further to the trig point/shelter. Back same way. A fine day with excellent views.
