If you click on Garden Pictures, and then 'Open Gardens' you will find various gardens which are open for visits. I remember putting a lot of photos on this about a French chateau garden we visited during the summer, for example.
It would be a good idea if GOY made a special category of gardens to visit though with some text about each.

thats what I was thinking Bertie Hywells blog looks a nice place to visit

Pamg - if you want to request something new on GOY, scroll to the bottom of the screen and use the 'Contact Us' link to send a request to Peter and Ajay who run the site

thanks Andrew i've found it and suggested it !
