"Rainbow beach tennis courts are the best and the newest courts on the southside of Chicago. There are 12 new courts, the park is well groomed, the 8 courts have lights. If you are looking for great courts to play on. I can't believe it, they are newly surfaced. There are bleachers to sit on, but I recommend that you also bring your chair, because it near the beach and a great place to relax and play."
