This review is especially helpful for those who have or use the following: Wheelchair, Mobility Scooter
The house was closed when we visited but the gardens are lovely and there is a mobility scooter which is free to use but booking in advance is advisable. There are accessible paths and the cafe is accessible. At present one of the toilets is closed so non-disabled visitors have to use the disabled toilet.
Transport & Parking
I think the loo is a changing places loo but please check in advance. It was very large. I didn't use it myself, I just had a quick look.
