Bring the whole family to Camp Foster YMCA for a day of free fall fun at the Iowa Great Lakes Fall Festival! Join us Saturday, October 17 from 10 AM to 2 PM for trick or treating, games, crafts and activities hosted by local businesses and organizations from around the Iowa Great Lakes. Kids can dress up in their favorite costumes and spend the day exploring everything happening throughout camp. With plenty of activities for all ages, it’s a great way to get outside, spend time together and celebrate the fall season in Okoboji.
