Nutsford Vale is an open space of rough grassland and woodland in the Gorton area. From the cache site you can practically forget you're in the middle of a city.
Formerly a clay pit, some work has been done to maintain the site as a space for recreation and wildlife. Some parts still suffer from the effects of fly-tipping, but the cache is located in a more pleasant spot, just off an occasionally-muddy path.
A local community group, Friends of Nutsford Vale, works to improve the location for visitors and for nature.
