I forget what it was, and forget the city-side destination, but there's a bus that goes to Penge that passes right by one of those stations.

Trying to remember if it's the Waterloo one that goes down Walworth Road, or if it's the Vauxhall one (36/436/185) that passes Camberwell Green from the other side.

I'll have to pay more attention the next time I'm in Camberwell. I prefer to avoid Waterloo, so I take the Vauxhall route more often, but because I've gone the Waterloo route so many times, the Penge bus is just as likely to be that one.

Suffice to say, I've never needed to go to Penge. If I did, I might have paid more attention to which bus I was getting.
