On the south road entrance into to the Oxford Science Park, just on the roundabout, lies a tiny park area. No one really visits this place as it has no real purpose ,evidence of this can be seen by the moss covered walkways. Come and visit this place and find my cache.
Follow the oval path into the small park area to find the cache. There is no parking here, so you will have to approach on foot. The closest village is Sandford-on-Thames.
