The park then fell foul of a century of neglect and decay until an ongoing programme of restoration was started in 1990, enabling it to be re-opened in 1993. It is now scheduled as Grade-1 listed on the National Register of Historic Parks and Gardens. It takes a 2.5-hour hiking tour to completely see each folly and their landscapes (a reasonable level of physical fitness and mobility is required and there are many steps, ascents and descents). At some times of the year, not all site trails are accessible.
