From New Radnor Village SO 21280 60809, via Whimble, Bache Hill, and Black Mixen, as Nuttalls 11.4Westdenewalker10/10/2017
Ascended from New Radnor via the bridleway which skirts the Rifle RangeDanMaisieBex01/09/2017
Parked up in the village and walked up Whimble first, then Bach Hill, Black Mixen and Great Rhos. Down into Harley Dingle then footpaths back to the village. Mainly following the Nuttall walk.Neolith28/08/2017
Two and a half hour walk from New Radnor I had no problems as it was a clear afternoon but would not want to be up there in poor viability.WAYNE ROWLETT21/08/2017
Knowle Hill - Whimble - Bache Hill - Great Creigiau - Black Mixen - Great Rhos. Basically the Nuttalls route with occasional diversions to take in the three bonus summits. Mainly cloudy and breezy but dry. Fairly dry surface with paths through the heather - judging by some other comments I was fairly lucky.Herbert Anchovy29/07/2017
With Shaky & Smithy from New Radnor. Parked in the village & took the steep minor road NW up to the forest at the top, following the track & then a very overgrown path to E of Whimble rejoining the track. Followed the fence N & then climbed over the gate to follow the fencelines to the tumulus on Bache Hill. Returned to path & then slanted NW along the edge of Black Mixen detouring to take in the summit. A fine walk round head of the valley to Great Rhos on dryish ground & then followed track at edge of danger area all the way down to Harley Dingle & round side of the hill back to New Radnor. A couple showers but great views & a great walk out.NotReallyABagger23/07/2017
Asked what I wanted for Father's Day and the answer was...the trig on Great Rhos. Failed this twice in 2015, and it didn't look good this time either with the heat, but a nice breeze higher up kept us going, and we finally bagged it. Like previous comments found the paths higher up were little more than sheep-trails through bog, my son went knee deep into mud at one point, and it was a real struggle to reach the trig even though the ground isn't that steep up there. Water-Break-It's-Neck was never more welcome at the end, the kids loved splashing in the cold water, and the Harp Inn at Old Radnor provided similar relief for the adults. Glad we did it, but probably wont be doing it again.Stuzinho17/06/2017
We parked at the car park for Water-Break-Its-Neck waterfall and headed up through the forestry and back down via Davy Jones' dingle. This was not a great route. The forestry tracks have significantly changed and we struggled to find a way out of the forest. Eventually, at the highest point of the track, we followed a very wet firebreak to an old gate, SO177625, and escaped. The RoWs on the hill have all but disappeared and are very difficult to follow. We followed a faint track to what used to be a gate, SO178633, (doesn't open, but easier to climb than the barbed wire sections). There was no obvious path, so struggled through tussocks and hidden ditches (and luckily through a gap in the next fence) to the summit. We did find a track heading south away from the summit, but that came to an end somewhere on the side of the dingle and we improvised thereafter until we reached the fields and the forestry which did have predictable paths this time. With Keith and baby Ross.islamidget13/06/2017
On circuit of Radnor Forest hillsPilch19/04/2017
Walked up from Water-Break-Its-Neck. Bit of a bog fest at the top. Beautiful day with lovely views.ronanhead05/04/2017
A fine circuit with 5 trigs, on a perfect sunny day. Beginning to be converted to TuMPing by Alex and co, and regaining proficiency in climbing barbed wire fences. From New Radnor, over the superb Whimble, Bache Hill, direct to Black Mixen (noooo - follow the track), edge of forest and peaty tracks to Great Rhos, then seduced away from the indistinct correct line to the forestry by Nuttall baggers track, but correct line regained off piste. Through forest, then up to Nyth Grug, Mynd, Black Brook track to A44, direttissima towards Molecatchers Wood, Castle Hill, and The Smatcher.Gill26/03/2017

Radnor forest circular walk: Whimble, Bache Hill, Black Mixen, Great Rhos. Very quiet despite a nice sunny day- I saw three more dead sheep skeletons than people, and I only saw three skeletons…Cas-gwent23/02/2016

From Water-break-its-neck car park skirting east of Warren Plantation; short climb and then about a mile on to summit. Perfect walking day, clear, sunny, cool wind. Back through forest and a quick detour to the waterfall.callumorr18/04/2015
tough going through the heather and deep snow. no view make sure you take a bearing to do correct descentAristotle Chip13/03/2015
With: hb; Followed path up the side of Fron Hill from New Radnor past the silent military range. Path from Great Rhos to north was devastated by tree felling.Ian Baines10/03/2015
Round of the three Radnor Forest Hewitts from New Radnor. Very windy.jim pererin10/01/2015
Continuation of walk from Fron-wen. Took track from Fron-wen east to forest road, which I followed south up steeply to Shepherd's Well. After some tougher walking SW (due to tree-felling) by bridleway to forest edge, I reached a gate at SO 18237 64461. From there a boggy path over the moor brought me to the summit. Walk continued to Black Mixen.marktrengove09/11/2014

From New Radnor - Mutton Dingle - Whimble - Bache Hill - Great Creigau - Black Mixen - Great Rhos.david23020113/08/2014
Parked car at car park for the delightfully named Water Break its neck waterfall. Carried on walking down the obvious track. At a junction of paths, one of which is to the left for the above waterfall,turned right over a bridge over Black Brook, walked up through the woods to join the path between Warren Wood and Fron Hill towards Davy Morgan's Dingle. Zig zagged up to the disused quarry, then joined track to crest of Great Rhos, at the 650 contour headed North West to find track North to trig point.Malbow09/08/2014
