You are looking for a small container that holds a log book. Please bring your own pen.
The cache is located near a park where there are swings, slide and a climbing frame for the kids however the cache is screened by vegetation so if you don't have any children, you shouldn't feel too obvious. Having said that please use stealth when needed. Please take care to rehide so the container can't be seen by passing muggles. There is no need to destroy any of the grasses or other plants in the garden. If you take a few minutes to stop, look and think about the name of the cache then you shouldn't have too many problems knowing where to look.
