Taking my Partner up Pen-Y-Fan in South Wales on Thursday, Been waiting for months to get back into the mountains and I cannot wait, stand by for a review of the day and pictures on Friday.
The plan is we will be doing a horse shoe style walk, parking in the car park under the north face of the mountain and then walking between the main spurs of the mountain eventually climbing onto the main ridge, when we get to Corn Du we will then traverse the small arete onto Pen-Y-Fan itself and then along the ridge again to the North and finally off the face of the mountain back to the car park. The weather looks passable, no snow or rain, a 35Kmph wind blowing to the East, so we will be sheltered from the worst of it until we are on the top of the mountain. The wind chill factor is going to make it feel about -4’c.
See bellow for a basic plan of the route
