When we first moved to Whiteley this area used to be a small play park for very young children but was very rarely used. In recent years it has been converted in to a quiet garden with benches. We often walk pass this place either on our way to the nearby shops or to the playing fields, so this seemed like a good place for our first hide.
You are looking for a 35mm film canister held in place with magnets. The immediate area is quiet but note that there is a nearby block of flats that overlooks the garden and this is popular pedestrian cut through so beware muggles walking by. The geocache can only accessed from inside the garden area.
