I think that may be the I-will-certainly-fall-over route, if it's the one that opens behind the tennis court? I've been both up and down that one, but not recently; on the night of the blood moon I set off to go down it and discovered that I had entirely misremembered how steep it was. I can't remember now if I didn't fall over due to extreme slow caution, or due to turning around and going back the other way.
