Most people seem to tackle this hill from the end of the minor road to the NE, but being still new to the extra width of Bertie-the-Motorhome (he's 4" wider than Colin), I was reluctant to take us down such a minor road just yet. Happily, some journeying around on StreetView had revealed a good place to park, just yards off the nearby B-road (at NJ 29414 57381) and we were happy to walk the extra mile in each direction.
So, up a tarmac track, serving some waterworks (amongst other infrastructure, a covered reservoir liberally adorned with solar panels - a good use of space, I thought) we went, onto a rutted track, and onwards to pass the falling-into-ruin buildings at Moniesmouie. Our 1:50k map suggested the track would end there. Our 1.25k map said it would continue and so it did - a rough track all the way up to the mast which lies a few moments away from the trig:
Interesting trig point
The trig isn't the quite the highest point but a step over a fence and fifty metres further brought us to a selection of heathery tussocks, one of which is apparently higher than the rest. I tried them all out for size, just to be sure.
A retracing of steps saw us back down to Bertie two hours after we had left, having walked 6.5 miles with around 750' of ascent.
With it being so close to noon by then, we might have stayed in position whilst we lunched, except that Bertie was parked in the frosty shade (he was nice and warm inside mind; I've now added "turn heating off" onto the pre-flight checklist) and, as he has a solar panel, it seemed a shame to waste all those lovely rays beaming down. A sunny relocation was thus negotiated, although it has to be said that as practical as a supermarket car park is (particularly when you need some supplies), it wasn't the most picturesque option!
