Parked by Hay Bluff an easy walk along paved Offa's Dyke pathphilhythe03/10/2017
Lovely day out in the Black Mountains with a nice circular 16km loop from Capel-y-ffin. Went up the steep slope of Darren Lwyd and then carried on along the ridge to Lord Hereford's knob/Twmpa. Then crossed the gospel pass to summit Hay Bluff, before following Offa's Dyke path back along Black Mountain and descending at the vision to get back to my starting point. Lots of Mountain ponies and ravens on the way. Also spotted a Wheatear and a few Swallows who can't be too far away from starting their migrations back to their African winter grounds.Gerry the Ranger17/09/2017
Around two hour, five mile county top walk from the free parking area on the Gospal pass north of Llanthony Priory. Over Hay Bluff and follow the Offa's Dyke path.WAYNE ROWLETT22/08/2017

Included in day's circular walk. Parked at Capel y Ffin, walked to Vision Farm, ascent steep east to reach Offa's Dyke Path and followed it north over Mynydd Du to Hay Bluff summit. Left Offa's Dyke path, turned west and crossed Bwlch yr Efengyl to bag Twmpa, onwards to Rhos Dirion, then 4 mile leisurely hike southwards along ridge to Chwarel y Fan, then descend to Capel y Ffin. Lovely area, much to see, and interesting people when you meet them. Chwarel y Fan was my last mountain of the 100 highest in Wales.Dewi Prysor14/05/2017

1st hill on my Offas Dyke path walk from Hay-on-Wye to Pandy. Probably the most indistinct Marilyn summit yet visited in misty conditions, visibility about 50 metres ahead. I did Hay Bluff the day before but Black Hill looked more exciting! Still plenty of Ponies on the route.Dazingdale19/10/2016
Just a stroll onwards from Hay Bluff trig. Cloud on summit so had no views, not raining though. Very quiet and peaceful. Company: Soloiandesbottes13/10/2016

From the Gospel Pass car park (beyond the stone circle). Via hay Bluff. Solo.ADT05/04/2016
Interesting route from end of road in Olchon Valley. Surprisingly rough going until we met the Offa's Dyke path. Misty so no views.jenx19/02/2016
With Jenx from Upper Blaen to the SE. At road head good parking near stream crossing. Old lane leads to sheep folds/firlds. Took direct line up stream to high gate N of that line. Zig zag up buttress (note would be hard in bracken season) then through heather and tussocky grass to ridge path. Summit cairn missing, one by path is not top. Headed little further south on way back to use old pony track /drainage line? more easily back to start.nordicstar19/02/2016
Long day ridge walking in the Black Mountains: Start from Llanthony, ascending Chwarel y Fan, Twyn Tal-y-cefn, Rhos Dirion, Twmpa, Hay Bluff, Black Hill, Black Mountain, Black Mountain South Top, Pen-y-Garn Fawr & Red Daren before a tired return to Llanthony. Super walk in the hills on a bright crisp winterís day.Cas-gwent18/02/2016
Could have done with some spikes on the way up.mike.hartley14/02/2016
with Alastair. Over Hay Bluff. Tent erected to provide wind shelter for SOTA activationM0YDH11/12/2015
Park next to the stone circle below Hay Bluff (not that we can see a thing in the low cloud)Asecending hay bluff following a stream (bach) we find the trig / Offas dyke path and a few walkers heading down in the deterioating now rainy weather. The good path spurs us on - finally we find the summit of Herefordshire (though there is not much to find!) and no view to be seen so we retrace our steps.briandavies18/10/2015
From the summit of Chwarel-y-Fan back down to Capel-y-ffin then up offa's dyke path to Black Mountain. Beautiful clear and warm day with excellent views.mcallmar25/09/2015
