There is Boston Mills and Brandy Wine which only has about 400 vertical feet. It's a tiny place thats pretty close, it's near Hudson. Then there is Holiday Valley (about 900 vertical feet) in Western NY, as well as Peek n Peak (700 vertical feet). The Peek is closer and is about 30 minutes east/northeast of Erie, PA. Peek n Peak tends to be A LOT less crowded then Holiday Valley, but it has fewer trails.
