I have given all the car park locations as grid references and I suggest that you buy a map of the area (OS explorer 1:25,000 sheet 217 is the best) and plot them and the cache locations and chose a route before you start. The series can easily be done in a day and a nice place to start is from the Shropshire Hills Discovery Centre in Craven Arms
Please be careful on the series, the roads up to the top of the Long Mynd and down the other side are steep, single track and unguarded. DRIVE CAREFULLY. The caches all involve some rough and sometimes steep walking
The 4 caches are:
From Church Stretton drive up onto the Long Mynd on the Burway but
TAKE GREAT CARE the road is very steep and single tracked. If your nerves are good risk a glance down into Cardingmill valley on your right. In WW2 soldiers were trained to drive the small tracked Bren gun carriers here. More than one turned over on the hill and ended up in the valley below.
Park by the track at the left of the road, grid SO 434 941, where you see a notice saying “authorised vehicles only”.
Follow the track for about 400 yards up to the hill where you will see a marker post and a mound of earth. From here follow your GPS.
Find the cache and read what it says about the guns then come back to the marker post and imagine what it must have been like.
