I attempted an approach from the east using the wind farms roads but seeing the numerous no access signs and a camera I decided against it. Instead I approached from the west using the cul de sac. I crossed a gate at the end of the road onto a farm road which continued onto a forest track. This ended at a small quarry which I crossed and was able to move quickly through a mature forest, over a fence and up to the trig.
I should have returned the way I came but elected to see if an approach by the northern end of the forestry would be easier using a wind turbine road.
I then crossed the field at the western side of the forestry but encountered a bundle of feeder bulls that had looked in the distance to be bullocks. I ended up making a quick diversion back into the forestry!
