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 tucked into a branch on a tree. Make sure you exersize stealth here as there is very little privacy at GZ.
