Whether you’re visiting for a weekend or planning a month of local outings, there’s plenty to enjoy.

Event dates and schedules change from year to year, so check official event websites before making plans. Popular events may require advance tickets or reservations.

Catch the Chicago Marathon

The Bank of America Chicago Marathon is one of the city’s biggest October events, drawing runners and spectators from around the world. It typically takes place on a Sunday in October, with a course that passes through many Chicago neighborhoods. Even if you’re not running, you can join the crowds along the route and cheer on participants. Check the marathon’s official website for the current date, course details, road closures, and spectator information.

Explore Open House Chicago

Open House Chicago, organized by the Chicago Architecture Center, invites visitors to explore buildings and spaces that are not usually open to the public. Past programs have included architectural landmarks, historic homes, cultural institutions, and behind-the-scenes spaces across the city. Admission and access rules can vary by site, so review the annual program and plan your route ahead of time.

See Films at the Chicago International Film Festival

Film lovers can look for screenings and special programs at the Chicago International Film Festival, which is typically held in the fall. The festival features films from around the world, along with opportunities to hear from filmmakers and take part in discussions. The program and screening locations change each year; check the festival schedule for dates, tickets, and venue information.

Enjoy Halloween in Chicago

As Halloween approaches, Chicago offers plenty of ways to get into the spirit. Look for neighborhood trick-or-treating, pumpkin displays, costume parties, haunted attractions, and family-friendly seasonal activities. The Lincoln Park Zoo’s fall programming is a popular option in many years, while venues and community organizations across the city host their own events. Check current listings for age guidance, ticket requirements, and operating dates.

Take in the Fall Colors

October is a lovely time to stroll through Chicago’s parks and lakefront paths. Millennium Park, Lincoln Park, and the Chicago Botanic Garden in nearby Glencoe are all worth considering for a seasonal walk. For a change of pace, visit a local farmers market or look for pumpkin patches and apple orchards in the suburbs. Fall color varies with the weather, so peak conditions may differ from one year to the next.

Make Time for Arts, Food, and Sports

October is also a great month to experience Chicago’s year-round attractions. Check theater schedules, museum calendars, live-music listings, and neighborhood event guides for performances and special programs. Depending on the season, you may also be able to catch a Chicago Bulls or Blackhawks game as their seasons get underway, or see the Cubs or White Sox if their schedules extend into October.

For a seasonal food outing, seek out menus featuring squash, apples, cider, and other fall favorites. Restaurant weeks and food festivals are not guaranteed to happen every October, but local event calendars can help you find current dining events and pop-ups.
