I found Otaru Snow Light Path Festival to be more magical than the Sapporo Snow Festival. Maybe it’s the juxtaposition of snow and fire – the lights are not bulb / LED lights. They are from candles. So there’s only one color – white.
The Otaru Snow Light Festival coincides with the Sapporo Snow Festival, so do hit them both at the same time. They are pretty cold though, so that’s also something to consider. Sapporo has three spots to go to (Tsudome, Susukino and Odori) on top of the other regular Sapporo go-to tourist spots. Adding up Otaru will make the trip longer and well, colder.
I’ve got all my tips in the article “Otaru During the Day”, so the items below are merely pictures of the place when I was walking all over the place.
