I'm back, and... I couldn't go up that darn hill. But almost. Was stupid and tried powering up straight, but started sliding backwards at the steepest part (36% according to Garmin) and had to capitulate and walk up to a bend. Zig-zagged my way up the rest, at an impressive 4 km/h. One day, I'll return and zig-zag up all of it.
Standing halfway up, trying to start up again. This was the easy part. The hard part is at the start. I didn't take photos of it, but just picture a tarmac-y wall in your mind and you'll have a pretty good idea.
Looking down from the top.
Edit: This is not my video, but it captures my experience pretty well.
