I am a photographer..looking to do a photoshoot. Just me and the model. Do I need to get permits for the photoshoot or I can just walk in??

Just walk in, and do your 📷 shoot

Nope

Just walk in! Maymont has that happen all the time on the grounds. in the house you might need special permission

I think you can just walk in.. Although they encourage you to contribute to the development of the park...

You can just walk in. I have seen plenty of photo shoots. They just walk around until they find their perfect setting.
