    Route Description for Pen y Fan and Corn Du Short Walk

    While the Pen-y-Fan and Corn Du Short Walk may be shorter than other routes up the mountain, the terrain is no less steep and will require you to wear proper walking boots in order to better traverse the rugged mountain terrain. Additionally, you will need to arrive early to secure parking and beat out the crowds, as this is the most popular mountain to summit in the entirety of Brecon Beacons National Park.

    Although it will certainly be a busy day on the trails, the breathtaking scenery from atop Pen-y-Fan and Corn Du is always worth experiencing. In addition to exploring the rugged, yet beautiful landscape of the Brecon Beacons, you will have an unbelievable sightline stretching out to the Cambrian Mountain in the north and across the Bristol Channel to the south. What an amazing way to spend a few hours exploring the natural beauty of Wales.

    Setting out from the south end of the Pont ar Daf car park, you will make your way east along the trail to a footbridge that crosses over Blaen Taf Fawr. After crossing the stream, you will continue uphill to the northeast, traversing the mountain slope over the next 2.0 km while enjoying the increasingly elevated views of the mountain landscape surrounding you.

    Arriving at a series of junctions in the trail, you will pass straight through the first junction and take the second path on your right at the next junction in order to continue on uphill, skirting around the summit of Corn Du on the way to Pen-y-Fan. Once you have arrived at the highest peak in Southern Britain, you will enjoy a spectacular sightline across Brecon Beacons National Park in every direction, including south across the Bristol Channel if the weather is clear enough.

    After revelling in the scenery here, you will head to the southwest along the trail to traverse the summit of Corn Du, which will offer some more beautiful views overlooking the surrounding mountains and valleys. Continuing on to the southwest, you will meet back up with your initial path and follow it back down the mountainside on the return to the car park, having completed the Pen-y-Fan and Corn Du Short Walk.
