Another visit. A walk close to home which I knew would be quiet. Did not see a soul. Probably last TP trip for some time.

Walked up from the dam at Usk reservoir. Thick mist on the ridge, no views from the trig at all. No sign of any Romans or Doctors either. Having said that - a great place to spend a couple of hours, something of an outlier from the Mynydd Du. "Tilestones" quarry workings clearly visible halfway up the ridge

Parked by the Roman Road and followed this for over a mile then veered to the right following the path up to Trig. A easy walk with stunning views

Parked by the trig then used the Roman Road to get to the Roman Camps and Y Pigwyn. Then headed SW on a track to Mynydd Myddfai and Black Mountain trig.

Very enjoyable walk in a lonely landscape, even though we arrived back at the car rather soggy and cold.

Parked by Twyn Henwen trig. Followed old Roman road for 2km and then a track to trig. Missed out the boggy ground. Great views.

Parked at the end of the track by Twyn Henwen which I bagged last year. Foolishly headed straight for the pillar over very boggy and tussocky ground. Good view from the trig. Followed mapped tracks for the return which was much easier on the legs!

Pleasant walk across dam and up through forest to open hillside. Trig is at summit of the HuMP Mynydd Myddfai. Pillar in good condition; original cap in place; 1 sight hole open; plinth becoming exposed. Excellent 360deg views, especially S to main Brecon peaks. A short stury concrete post lies prostrate next to the trig with 'WD' chiselled into the to of it - War Dept maybe?

A pleasant walk up from the car park at Usk Reservoir. The photo was taken looking East towards the fenced off easement for the controversial LNG pipeline which is now being reinstated to a very high standard
