Locals call it a Park because that is what they've always known it to be. Arboretum means Tree Park and as from 1874 over 3,000 tress large, small, evergreen, deciduous, well known and lesser known have been planted. This makes it an Arboretum.
Knottingley Park is a great place for cricket, horse events, kennel club shows, camping, picnics and walking. There is a BBQ available (50c coin operated).
Knottingley Park also has a relica of an early bush hut built in 1864 and has an extensive playground.
