Location of Gate 2

Hi, I'm volunteering for the first time this Satureday July the 6th at BST, and need to know the location of Gate 2 in Hyde Park please. Probably the closest tube station would help. I don't live in London, travelling from the North West, so any friendly advice welcome. Thanks!

Gonzalo,

Did anyone get back to you. I also am from outside London and would like to know the location fo this gate

Now that there have been some of the BST gig series - is anyone able to advise? Is the nearest tube station to Gate 2, Marble Arch? A steer from someone would be great.
