In reply to Dan Bailey - UKHillwalking.com:
I remember doing those ones in a white-out. I'd driven up from Cheltenham one Easter weekend and was determined to get up some hills, so I picked some that didn't pose too much of a navigational challenge in bad conditions. I did a bit extra, by parking at Balsporran (before the cottages were done up) and went up Geal Charn at the start before heading on to A'Mharconaich and the others. The downside of doing that route is that you end up at the A9 dome way from the start point, but I managed to time my walk to finish with someone who had a car at the big layby on the A9 and they very kindly gave me a lift back to Balsporran. Good day out.
