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 suggest completing the route by bike.
All caches are accessible on foot too though 
Sinfin Moor Lane bike path starts here, you shouldnt run into many cars on this highway though as motorised access is now controlled. You are looking for a small cache hidden in plain sight; a trackable was placed in this when it was launched but the container has since be shrunk in responce to a muggling. Coins might still fit? I have made Sustrans aware of this cache and have received permission from the route manager.
