No lines, vast area, friendly people, low prices
No highspeed lifts, a bit out of the way
I spent an entire week at Bridger and simply loved it. I found its trails to be well laid out, with very few cat-walks or having to walk far. I took an intermediate group lesion that was just me and my buddy because there were so few people there. I also found the instructor friendly and helpful. The lodges were nice, and everything (including the beer) was reasonably prices for a resort.
They also have great multi-day packages that are a steal.
Everything I look for in a fantastic resort was at Bridger Bowl.
