Although you can park very close to the cache from the John
Lewis carpark, I would suggest parking up and walking to the trail
head to see the ASDA roof in a really bad condition.
You can see from the local OS map that there's two routes you
can take, but you can't see the handy gap in the John Lewis fence
for accessing the path.
The cache shouldn't be too muddy under foot, so ok for smart
dress. If you spend some time and do the walk, you should be back
in your car within 10 minutes.
Depending on traffic conditions it may take you a little while
to get back on to the motorway. In normal conditions it's two
minutes drive from J4. ENJOY!!!!!
