U.S. National Whitewater Center: Trails are marked for ability levels and the center offers 20 miles of bike trails. In addition to the trails, there are tons of hiking trails and family-friendly activities.
Freedom Park: An easy loop for younger riders. It's nice and flat with plenty of space to stop as needed and wide enough that kids of all abilities can move at their own speed. If you're looking for a longer ride you can catch Little Sugar Creek Greenway right at Freedom Park.
Anne Springs Greenway: Great for more adventurous bikers, 40 miles of mountain biking makes for a great day out! In addition to the trails, they have several hikes that are great for kids of all ages.
McAlpine Creek, McMullen Creek, and Four Mile Creek: This greenway loops and connects all these differed entrances to the 5.8-mile route. The path is a smooth boardwalk, gravel, and asphalt making it one of the easiest rides for families in the area. The Greenway can get very busy on the weekends so make sure your kids understand the rules of the path directions and stay right or left depending on what direction you're traveling.
