It's alright. Park was very mediocre compared to Blue Mtn or MSLM (which if you're from Ontario, I'm sure you've been to), in the past. Haven't been there this year so I cannot say for this year. Me and my buddys would drive 3.5 hours to go to Blue and MSLM over Holiday for park even though HV is an hour away.
Overall skiing is alright. Only 700' vertical, so it's not exactly leg burning, and not too much steep stuff. Good bump runs though.
The vibe is good though, and the bars in Ellicottville can be a shitload of fun.
Snow can be good, they have a really powerful snowmaking system, so coverage will be good, but it gets icy often if we aren't getting much natural snow. We've gotten 3-4 ice storms this year, so it's been hit or miss, and the lake effect dumps haven't really come this year.
What week are you going to be there?
