Haysden Country Park covers an area of about 65 hectares (160 acres) in the Medway Valley, to the west of Tonbridge. It includes a range of habitats such as river, grassland, freshwater lakes, marshland and woodland. The site is designated as a Local Nature Reserve and in part a Site of Nature Conservation Interest. It has also been a Green Flag Award wining park since 2006 and is a Natural England accredited park.
The park stretches from Barden Lake at its eastern end, westwards to Haysden Water. With the River Medway running along the northern edge, with the Environment Agency Leigh Flood Relief Barrier and Storage Area providing a crucial role in the protection of Tonbridge from the threat of flooding.
Covering an area of former agricultural land on the Medway Flood Plain, the park contains part of the Straight Mile, and the Stone Lock, constructed in 1830 as part of the unsuccessful Meday Navigation Canal. More recently the site had been used for sand and gravel extraction, which was processed and distributed from Haysden Water. These works altered the landscape of the area and created Barden and Haysden Lakes. Once the gravel workings were completed in 1988, Tonbridge & Malling Borough Council created the park.
