I went to the Harbin Ice Festival last night with a group from the hostel where I'm staying. 280 RMB (about US $42) got me entry to the festival, plus transportation to & from the festival grounds.
Our guide dropped us off at the entrance, saying that we should meet her back at the van in two hours. She said that we were lucky because it was warmer today than it has been recently. Instead of minus 30 degrees Celcius (about minus 22 F), it was only minus 20.
In addition to taking photos of the ice & snow sculptures, there were several other things you could do there.
I zinged down the ice slide more than once. Wee!
Even though I had all my state-of-the-art snow gear on, my fingers & toes were pretty cold after about an hour. I ducked inside the warm-up tent, happily paying 40 RMB (about US $6) for a Lipton tea, & sat down to watch the goings on in comfort.
There is apparently another festival grounds where they have many more snow sculptures on display. The ones I saw were pretty impressive. Since the snow sculptures aren't all lit up with neon like the ice sculptures, I think I'll go over to that one in the day time, when it's a bit warmer.
