Awesome hike on I-90. Starts out pretty flat, but definitely get steeper later. Beautiful lake, especially when it's frozen. Not a ton of places to sit at the top, particularly when it's covered in snow, but you can walk a little bit around the lake. Parking lot is huge, and I've not had a problem with finding parking in the past. It's also practically right off the highway, so driving to the trailhead is not usually an issue in the winter.
