South London hills

Back on the topic of hills in South London, I stumbled across Canonbie Road the other day, just between East Dulwich and Honor Oak. It's well short, but fucking steep, way harsher then Gypsy Hill etc. I nearly did the 'going backwards' thing

Stunning views from the top.

EDIT: Just realised this was discussed on the first page. Well done me.

Streetview is great for getting a sense of these climbs.
