Wallington

Formal gardens, walled garden (most of), widlife hide, blue/green walks and house all accessible. The only walk that is not possible is the riverside walk. Nice cafe so you can spend a whole day here if you want.

The main parts of the grounds are wheelchair accessible, albeit a little bumpy in parts. Having a sturdier machine, I was able to access some of the more rugged paths but I saw people on these using the NTs own hire mobility scooters quite happily. There's lots of birds here, several ponds and red squirrels.
