Chicago has so many gorgeous, historic, and architecturally divine parks throughout the city it's hard to pick just a few to visit. Luckily they're spread not too far and wide, so give yourself a day or two, throw on some quality walking shoes and go explore!
Grant Park, above all, in my opinion is a must visit for those who love massive pieces of history that'll make your jaw drop.. casually. I'm talking Buckingham Fountain. Dedicated in 1927 this fountain is one of the largest in the world and being in it's presence silences all head noise, giving you a feeling of appreciation and tranquility. I thought I was just going to stroll up, take a couple pictures and head out but I couldn't get myself to walk away. I sat on one of their many benches and stared at the beauty of the city, water patterns, and appreciation on other viewers' faces. Definitely a must see, and hey, take a picnic, you may want to stay a while too! Note: The fountain does not run during Winter. They say, generally between October - April but I'd check the website for more info.
This park also has historic statues, including one of everyone's favorite: Abe Lincoln. There's tons of geese around in the late Summer, other birds and bees, but no massive wildlife that I've seen or heard about. I saw many parking lots around the area but could not tell if you they are ever free. I'd recommend not driving/parking anywhere in the city but that's my personal preference due to lack of patience and love for my car's well being. They have free public bathrooms on site, access to the walking path alongside the lake, and food vendors very close by. I'd love to attend an event here some day as I hear it's quite a legendary experience!
