About
Castlewood State Park Shelters provide covered day-use picnic facilities in one of the St. Louis area's most popular parks. Located along the scenic Meramec River in Ballwin, Missouri, the two shelters offer group gathering spaces with charcoal grills for cookouts. Shelter 1 accommodates up to 75 people with two 3x3-foot grills, while Shelter 2 holds 50 people with one grill. During the on-season from April through October, flush restrooms and water fountains are available near each shelter, along with dumpsters for trash disposal. Shelter 2 also has a volleyball net. During off-season months (November-March), only vault toilets at Lone Wolf Trailhead remain available, and visitors must bring their own water. These are day-use facilities only with no overnight camping permitted. Reservations cost $100 per day and can be made 30 days to 12 months in advance online. On weekends during the on-season, shelters are available free on a first-come, first-served basis. The 1,818-acre park offers hiking and mountain biking trails ranging from beginner to advanced, plus fishing access on the Meramec River.
