Kathy Osterman Beach is located in Chicago's Edgewater Neighborhood. When I visited the beach in October 2014 the weather was comfortably cool. There were only a few people relaxing on the beach and every once in a while a biker or jogger would come by the path behind me.
I feel the beach is the best in Chicago. It features a new beach house and smooth pure sand. I'm not sure what it's like in the summer but in the fall it was insanely peaceful. The only sound was faint chirping from some seagulls by the water and occasionally a siren or horn broke the silence.
Lounging on the wall, having a snack and looking at the waves was a great way to take a brake from the busy city life.
