When we started walking up Fan Fawr in the Brecon Beacons National Park, we had no idea that we would end up walking out of the low cloud. The cold and damp fog hung around us in the car park and it looked like another walk without a view. However, as we ascended the mountain opposite Pen-y-Fan, the mist starting clearing until we stood above the cloud line. And the views were incredible. Looking down, we could see the valley filled with dense fog and a bright blue sky above.
