You are looking for a camouflaged container, hidden on the edge of a public footpath with appropriate cover, pretty straightforward really....
........unless of course you have an aversion to a specific evergreen plant.
The site borders woodland known as Albert Plantation, in an area which once formed part of the grounds of the long gone Sprotbrough Hall. The creation of the A1(M) Doncaster bypass in the 1960's dissected the Eastern edge of the estate.
Visiting the cache can be part of a circular walk from several directions. There is access via the nearby footbridge over the motorway from the Sprotbrough Park area, or via Ings Lane from either the Trans-Pennine Trail, or Sprotbrough Road.
The container can be reached from the footpath, there is no need to enter the woods themselves.
