Family Things To Do in St. Charles MO

Whether your kids are toddlers or teenagers, St. Charles County has something to offer every weekend. The county's park system is excellent, the library hosts consistent free programming, and the community event calendar stays full from spring through fall. Here are the highlights.

Frontier Park and the Missouri River Waterfront

Frontier Park in the City of St. Charles is the gateway to the Missouri River and one of the best free outdoor spaces in the county. The riverfront park features open green space, walking paths, and stunning views of the Missouri River. It's the home of the Katy Trail trailhead, multiple community events throughout the year, and a favorite spot for weekend walks, picnics, and outdoor family time. Kids love watching the river, and the open space gives them room to run.

Katy Trail for Family Biking

The Katy Trail State Park stretches 240 miles across Missouri, and St. Charles is one of its most popular and accessible entry points. The trail is paved (crushed limestone), flat, and follows the Missouri River — making it ideal for families with young riders. You can rent bikes nearby or bring your own. Even a short out-and-back ride makes for a memorable morning. The scenery along the river bluffs is genuinely beautiful, and the trail is peaceful and well-maintained.

Klondike Park

Located in Augusta, Klondike Parkis one of the hidden gems of St. Charles County. The park features mountain biking and hiking trails through rugged limestone terrain, primitive camping along the Missouri River, and some of the best river views in the region. While the mountain bike trails are geared toward intermediate to advanced riders, the park's hiking trails and campgrounds are perfect for family adventures. Pack a cooler, set up camp, and let the kids explore the bluffs and river access points.

St. Charles City-County Library

The St. Charles City-County Library system is one of the best free resources for families in the county. With multiple branches across St. Charles County, the library offers regular free programming for kids of all ages — storytime for toddlers, STEM activities, summer reading programs, craft workshops, and special events throughout the year. Check their events calendar weekly; there is almost always something free and engaging happening at a branch near you.

Discovery Park (O'Fallon)

O'Fallon's Discovery Park is a beloved family destination in the eastern part of the county. The park hosts seasonal events, outdoor activities, and community programs that draw families year-round. It's a well-maintained green space with room for picnics, sports, and exploration — and it connects to the larger O'Fallon parks system.

Farmers Markets

The Saturday morning farmers market circuit is a St. Charles County family tradition.Market on Main on Historic Main Street, the New Town Farmers Market, and other seasonal markets across the county make for a perfect low-key weekend morning outing. Kids enjoy the energy, the fresh produce, and the vendors — and parents appreciate the coffee and the local goods. Most markets run from spring through fall.

Family Arena

Beyond concerts, Family Arena regularly hosts family entertainment events — touring ice shows, circus acts, family-friendly comedy, and youth sporting events. Check their calendar for upcoming family shows, which tend to sell out quickly when popular acts come through.

The Christmas Traditions Festival draws hundreds of thousands of visitors each year for a holiday market, live performances, visits with Santa, carolers, horse-drawn carriage rides, and festive storefronts along the cobblestone streets.
