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

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
