Parked by the lonely phone box and followed the forestry track up to the small llyn. Tried to approach the trig through the forest from the SE but was thwarted by impassable windfall. Beat a retreat and then followed the track to the S then along the easy ride to the pillar. Decent view to W. Cap still in place. Had planned to backtrack to Nantymaen and follow the bridleway to Garn Gron, but I could clearly see the trig silhouetted against the skyline and on the spur of the moment decided to head straight for it.

Parking at dilapidated phone box on mountain road at entrance to Nantymaen farm. Excellent forestry access road to pools, then a filthy thrash through felled section of conifer plantation to finally top out and find the hill clear felled to the W giving some outstanding views. Pillar found with a blank original cap; rear sight hole open. English language passive plate has been forcibly removed - the Welsh love the English really!

I adore this area of mid wales and cannot fault it. Todays trio started with a cycle in from the South on well made track. At spot height 511 go west around small llyn up a muddy forest track. Once you reach the high point the area to theNorth has been clear felled - opening up some wonderfull views towards Llyn Du and beyond. Another classic and worthy of a visit. Pillar is in very good condition with some flaky painton the flush.

polaris: if the gate at spot height 392 had been open I could have tried out my rally driving through the forest as far as the pool below the TP .

nly know it was August 1979, so the 15th is a guess!
