Decoy Country Park provides an opportunity to enjoy formal playing fields and a large children's play area with a water play feature. Other popular amenities include a lake supporting water sports activities and a deciduous woodland with a trim trail incorporated into it.
Decoy was once a clay quarry but now supports a wealth of wildlife, with the main habitats being ponds, streams, fen, wet woodland and heath woodland. Parts of the Country Park are either a County Wildlife Site (CWS) or a Site of Special Scientific Interest (SSSI). The Park provides opportunities for quiet countryside recreation such as walking, wildlife watching, duck feeding and picnics, with good wheelchair and pushchair access.
