If you’re visiting our house, gardens, Tea Shed or plant centre, you are welcome to park for free in our spacious car park. Just follow the drive through the estate until you see the parking signs. Disabled parking bays are available next to the main entrance.

Last entry to the garden is at 4pm, and the car park gates are locked for the evening when the gardens close at 4.30pm.
