Highlighting Ballwin

Castlewood State Park

1401 Kiefer Creek Road
Ballwin, MO 63021


In the early 1900s, the area that’s now Castlewood State Park was a popular retreat for partying St. Louisans. The dance clubs are gone, but the winding Meramec River and the lush valley that surrounds it remain. The park has hiking and mountain biking trails that range from those great for first-time riders to ones that even the most experienced will return to time after time. The park is considered one of the best mountain biking locations in the St. Louis area. Good fishing, broad meadows filled with wildlife, and plenty of recreational facilities make the park a favorite for people who want an adventure or just to get away.

Picnic Areas

Fifty picnic sites are scattered throughout the park. Each site consists of a picnic table and pedestal charcoal grill. Sites are available at the lower picnic area near the Meramec River, along Kiefer Creek, near the playground and at some trailheads.

Equestrian picnic sites are available at the horse trailer parking area. Equestrian sites have a picnic table, pedestal charcoal grill and hitching post.


If you need a place for a family or company picnic, rent one of two picnic shelters.

Shelter 1 can comfortably seat 100 people and has two 4'x4' barbecue grills;
Shelter 2 seats 70 people and has one 4'x4' barbecue grill.
Each shelter has a water fountain, a modern restroom and play space for volleyball, soccer, softball, horseshoe pitching or other group activities. Volleyball nets are provided, but you will need to bring your own recreational equipment.


To keep the kids entertained, there is a playground conveniently located in the middle of the field between the two picnic shelters.


Take advantage of several miles of Meramec River frontage throughout the park to cast your line for channel catfish, flathead catfish, carp, drum, gar, walleye, crappie, bluegill, longear sunfish and bass. Access the river via the concrete ramp or at numerous spots along the River Scene, Stinging Nettle and Al Foster trails. There are a number of deep holes, shallow ripples, under cut banks, logjams, root wads and rocky areas that provide cover for the fish.

All statewide regulations and license requirements apply.
