The torrain is basically flat, continuing on the well maintained wide public footpaths, down 'Park Lane' (except for the actual cache, which is hidden 20 foot up a bank).
Follow the footpath as it goes through a tunnel/bridge under the railway.....
....keep following the path, until you see the "JP", and at the big tree, go up the bank on your left (there is a kind of path !). This location is totally geo-kid and doggie friendly.
The cache is a small round container, containing a log book and usual goodies.
