The fun part is if you try to be clever and keep riding round the corner to the bottom of the canal steps. The wooden slats grip perfectly well when at 90* to your wheel. Suddenly encountering the slats at the steps, turned 90* round again, while leaning into the corner always provides for some interesting front wheel behavior. Many an icy Autumn or Winter morning commute back when I was at school taught me it is probably best to dismount when going up there if nothing else.
Of course, then you have to stop and dismount while still on the main path, on which everyone else is now expected to be doing the same according to the signs even if they're going straight on. I mean it's been fine for literally 10 years or so hasn't it?
