How do you get into the garden and do you need a pass?

Yup

Yes you need a pass.

The garden is accessible from the main parking area at Castle Hill, they are do the west of the Great House down the woodland path. You can book a pass in advance or purchase at the gate as long as space is still available. Space does fill up on nice days and we do often sell out on weekends when the weather is fine. Visit www.thetrustees.org/castlehill for more information. You can also book your passes directly at www.thetrustees.org/passes. Hope you enjoy your visit!
