Great trip! Unless you are intending to run it allow 5.30 (hrs/mins) to complete the walk. Good views all around can be very wet under-foot so good walking boots advised.  This is quite a strenuous walk so take both water and some food with you.  This walk covers the four peaks in one go and is 20km our average moving speed was 4.3km/hr.  The initial push from the car park gets the heart working then there is a nice steady path from there on until the peaks. The last part of this walk comes down very step and is quite hard then it’s a steady trek back to the car park with a last small hill (on the road).

We walked to Pen-y-fan in about 3 hours in the evening and then spent the night up there in bivvys. Saw loads of shooting stars. We trekked back around the next morning it took us about 2hours. This route is an amazing way to see some amazing vistas. The climbs are challenging but there's no rush! All the trails are along the top of mountain ridges with some lush water features. Only about 2k at the end on a road back to the carpark.
