There’s a lay-by for vehicles just at the start. It’s far enough away from Pen Y Fan to not get busy

Great photo opportunity, but the area can be busy depending on the weather and it’s likely any progress on a bike would be very slow. Early mornings and evenings are good.

When coming off the mountain to go down towards the car park it’s quite a steep scramble and can be slippery
