06.55 Easter Sunday. Glorious sunny quiet time to trespass on MOD land to this TuMP summit and trig beyond to the NE.vegibagger21/04/2019
Groundhog Day as Im back here again a week later for another try with more research and determination, and uncannily only a day after the official Groundhog date, and ,as the little critter forecast in the film,snow has indeed fallen, with Wiltshire blanketed under pristine snow. Unavoidable to not leave a long trail in the snow which was like towing a huge arrow saying I am here. Beautiful dawn. -6 degrees. Army landrover moving not far away - even at dawn.At the foot of the hill is the Porton Down South Defence Chemical Biological Radiological and Nuclear Centre - they run military training and scenarios ( on this hill perhaps?) in these grim areas of threat. The 2018 novichock poisoning was close to home on their doorstep in Sailsbury. WW1 trench mortars were developed and fired here.Chris Pearson03/02/2019
From Figsbury Ring car park. Corner, field edge, past barn then tracks. No one around, but flags flying HP in woods.PeterD11/11/2018

Thorny in more ways than one!Chris Peart25/12/2015
Parked at Figsbury Ring. Had to scale a high barbed wire fence and ignore the fact that it is an MOD DANGER AREA and that a red flag was flying. Couldn't hear any firing and didn't see anyone so all OK. Easy and fairly pleasant walk to a patch of scrub.Herbert Anchovy17/09/2015
