Alton Towers is launching guided tours of its famous house and gardens this summer.
Costing £10 per person in addition to theme park entry, the two-hour tour is available between 3 July and 14 September.
The length of walking is given as 2.5 kilometres, or about 1.5 miles.
The tours will only be available on Wednesdays and Saturdays, with pre-booking done via the Alton Towers website.
The house – known as the towers ruins – was completed by Augustus Pugin, a pioneer of Gothic Revival architecture.
