Snow Valley is in Big Bear, before you get into the town, at a lower elevation than Bear Mt. and Summit. Rode it once years ago and it was pretty janky, they have a weird lay out with lifts that go up then down then up again. I was there with really low visibility conditions and I got lost haha. Back then they didn't really have a park but I guess they have some stuff now.
Its definitely worth just driving the extra 15-20 minutes to the other mountains if you drive all the way up there, but if you had a free pass it'd be cool on a really crowded weekend or something when the other resorts are packed.
