Charlie, I've lived here my whole life (24 years) and I still ask myself that question haha
The Watkins Glen state park is beautiful and since you'll be right in that area you should stop in. I'm through there now and then for work I live about 45min north of Watkins.
Like George said, the Wineries. Route 14 North heading out of Watkins has quite a few all the way along the stretch up to Geneva.
