Heavy cloud cover that begins to break up around the end of the day can offer some of the most ridiculously dramatic light. The best I've ever seen was atop Tom na Gruagaich, one of Beinn Alligin's two Munros, huge spotlights of sun playing over the tremendous Torridon mountain landscape.
With a similar forecast in prospect, being in the same area, and strongly guided by these memories rather than braving somewhere new, I found myself atop Tom na Gruagaich once again. The cloud began to break up, the bursts of light began to spill through, and it was all happening again.
Except this time there was a rainbow arcing over Liathach to add to the epic feel. I look forward to my next time up here, when I expect there'll be prancing unicorns in the foreground.
