Penwyllt to Ystradgynlais

I was asked the other day, if it was still possible to walk from Penwyllt Quarry down to Ystradgynlais.
So challenge in the making, I went to find out.
Results : Yes it is possible, couple of tricky areas, such as overgrown gorse bushes, but quite easily overcome, along with a lot of boggy areas, again easily overcome
Route is approximately 3 hours, adding on another 30 mins for breaks. 
Route length approx 8 miles depending on where you exit in Ystradgynlais.
