Additionally the Grotto will be open during the first weekend of the annual Civic Trust Heritage Open Weekend, September 14th and 15th 2019.
Visitors are advised to wear flat shoes and bring a torch as the floor is uneven and the entire underground system is unlit. In the garden there are steps leading down to the grotto and up to the summerhouse. Visitors are requested to stay on the paths leading to the grotto and summerhouse and not to climb the banks. Unfortunately, there is no access for wheelchair users.
