This cache is part of the "Get your kicks!" caching trail along Derby's radial bike route, Route 66!
As this bike path is very well maintained by Sustrans, I would strongly recommend completing the route by bike.
All caches are accessible on foot too though 
You are looking for a bison cache here. It is placed at the edge of a small thicket of trees, just off a little footpath.
There's a little petrol station/ garage nearby, hence the name :)
