I think they are the only one that stays open year round?
Island View used to, but it’s been at least 10 years since I’ve been up there. Some of the best memories as a family has been in the lodge at Island View. I remember the Murphy beds they used to have, my brother and I always joked that there were dust bunnies the actual size of bunnies behind them…
I’ve been going to the Thunderbird in early October for the past 6 or 7 years and went up there in mid-Janurary of 2017. There was a decent amount of snowmobile traffic there over that weekend. Haven’t stay anywhere else up there
