Pillar in excellent condition with asphalt plug. Small memorial plaque. Though in open space no real views due to trees.

An enjoyable walk around Hafna Lead & Zinc Ore mine trail. Leads to the top of the 139 steps. Go left until you reach the summit.

Walk up from old lead mine workings car park. Up steps and on uphill to 2nd stile. Stone built pillar. View to Moel Siabod through trees. Lovely position next to cottage.

Short walk up from the mine car park. keep following foot path until you reach second style. Turn right along fence line/wall on your left behind house. Nice views slowly being obscured by trees. Stone trig in good condition ??

Pleasant walk up from the disused Hafna Mine with it's mill buildings and info boards arranged as an open-air museum. Pillar in sheep pasture in mixed woodland. Stone-built with a cheap composite memorial plaque attached just above the FB. Cap missing, asphalt plug; LHD side sight hole closed, other 3 open; spider off-set to one side of top. Minimal views above tree tops

Our plan for today was to complete 22 geocaches and this trig point. All went to plan, although, we ended up in the pitch dark for the last half hour. Easy walk up the pillar.

Spotted on map while Geocaching in the area. Quick dash up the hill - nice to find something slightly different.

Stone built pillar, in a nice clearing, close to footpath up from the Hafna mines (which was quite interesting) Views restricted by trees, but could see the higher peaks of Snowdonia through them. Pleasant spot

Easy free parking here at the old Hafna Mine. Climb the steps through the mine workings and follow the footpath until you’re just south of the pillar, then follow the property boundary fence line. The pillar is built of local slate rather than concrete, and is in nice condition. The centre plug has been replaced with bitumen filler but all the other metalwork is intact. Visibility is restricted by trees but what you can see is very pleasant.

Walked up from the B5106 near to Gwydir Castle and then after locating the trig I returned back to my starting point via the Afon Llugwy and Betws-y-Coed. The stone built pillar looked good, but the views were unfortunately a bit of a disappointment.

Quite a taxing walk up from Llanrwst along minor road. Then through the ruins of Hafna mine & mill to get to the trig. Nice.

Walked up from Hafna mines where I'd been an exercise casualty for a first aid course. A nice walk up, some lovely cottages dotted around. A place of peace and solitude.

Large, square, stone pillar. Tarmac plug. Public. Forestry Commission. Snowdonia National Park. Take scenic forest road from Gwydir Castle, then public footpath up through Hafna mine ruins. Trig at top, in clearing, just to right above path.

Parked below the preserved remains of Hafna mine.Footpath takes you up through the mine structures and further to a clear area on top. Another local stone built pillar and to our eyes looked a little fatter than other similar pillars. There are limited views to hills in the east(at least I think it was to the east). Has a plate stating a dedication from local ramblers.

The pillar is in good general condition but the views are not that spectacular.Moel Siabod provides a little bit of interest from this site.

Celebrated having finished my circuit of Welsh 2000ft summits in 2006 on Tryfan a few hours earlier by parking up SE of this trig and taking the walk up on easy trigs. Fading light limited views.

We parked at Hafna Mine to the west on the road from Llanrwst. Nice walk up from the carpark past the old workings then follow your nose. Local stone, tarmac plug.

Stone built, in reasonable condition, three sighting holes open and amazingly clear so could see the upper center mark. It is not actully square so the spider is off center, plus is some sort of tary stuff.

Lovely little back lane off the A5 and then a pleasant walk through the forest. The pillar is made of rough slate blocks and is almost rectangular. There is a plastic plug replacement. The stout concrete base is about 6" proud of the surface on a low mound. Sadly, the views aren't as good as I'd hoped - mostly restricted by trees but to the East you have a good panorama of 3 wind turbines of which no sensible architect would be proud. Incidentally, there are some very odd calcium carbonate deposits on the north face - almost like stalactites!
