A fine viewpoint, but the cairn has gone (was getting a bit big).

Not much remains of what was once the highest castle in England and Wales, but it is still an atmospheric place with great views.

The Black Mountains are usually known for their broad flat ridges, but there are a couple of more narrow ridges leading up to the tops. The Dragons Back is one of them, climbed from Pengenffordd and the walk leads to Waun Fach, the second highest mountain in southern Britain. The ridge also includes Castell Dinas which was the highest castle in England and Wales at 450 m (1,476 feet)

Great walk that's pretty accessible for most people to achieve, challenging but doable! The route I took incorporated Lord Hereford's Knob. I published it on Komoot here: https://www.komoot.com/tour/1576268965 And on my blog here (with extra commentary for my own entertainment!): https://weekendwalk.co.uk/route/hay-bluff-walk/

The Dragons Back walk starts in the small village of Pengenffordd within the Brecon Beacons National Park. The highest summit of this black mountain range that’s located in Southern Wales. Called Pen y Gadair Fawr or known as Waun Fach summit is that at a height of 811 metres it is the Second highest summit in the Southern of Britain!! Offering a fantastic 360 panoramic views of the surrounding country side and the beautiful Black Mountains. It’s Utterly mesmerising to witness! It’s like the Eyes can’t even begin to tell all of what they see! The first ascent of the walk takes you over the ups and downs of the ‘Dragons Back’, aptly named due to its shapely mounds that resemble a sleeping dragon. This area has grazing livestock and wild ponies roam the hills. Please keep ALL dogs on leads throughout this walk to ensure safety. Farmers do have the right to shoot any dogs that are not on a lead or under any kind of control!!! Be prepared for the serious repercussions farmers now have to take extreme measures to protect their livestock! It’s UNLAWFUL It’s totally Unacceptable behaviour from any specific species human or the four legged kind! It’s now become a real problem to the current local farmers! So unless you want your dog Shot keep it on a lead!!! TO MANY BRUTAL ATTACKS HAPPENING ON LOCAL CATTLE ARE GETTING ATTACKED AND KILLED BY WALKERS DOGS!
