Horton Country Park is a 152.3-hectare (376-acre) Local Nature Reserve north-west of Epsom in Surrey.

[1][2] The park is a wooded recreation and amenities area occupying the east of a narrow upland watershed between two tributaries.

As such, the summit being the parish divide, it is in traditional terms, within Epsom parish and occupies land due west of the town, and due east of the semi-rural, semi-urban London district of Chessington.

[3] Part of the area is occupied by Hobbledown Children's Farm, which contains various folkloric themed adventure playgrounds and a small zoo hosting domestic farm animals, and exotics such as meerkat, nilgai, emu and Bactrian camel.

Parts of the landscaped grounds of these hospitals have now been incorporated into the country park.
