Chicago's 'L' elevated train is the backbone of getting around — a single Ventra card (or Apple/Google Pay tap) covers all CTA trains and buses at $2.75 per ride as of 2026. A 3-Day CTA Pass at $15 is the best value for most visitors making multiple rides per day. The Red and Blue lines run 24 hours. Skip renting a car in the city. The Loop's one-way streets are confusing, hotel parking runs $50–$70 per night, and the combination of the 'L', Metra commuter rail, and rideshares covers every neighborhood you'll want to reach.
