Located in the Lincolnshire Wolds, Cadwell Park was established in 1934 by Mr Mansfield Wilkinson of Louth. Some of the bends are named after family members e.g. Mansfield, Charlie and Chris. It is now owned and operated by Jonathan Palmer's Motorsport Vision company.

It is sited across a steep-sided valley, giving rise to dips and crests. The circuit features sharp changes in gradient, including one section called The Mountain where bikes can become airborne by up to several feet. Its mix of challenging corners has led to its nickname as the Mini-Nürburgring.
