Castlewood is a great place to get a fairly challenging walk or trail bike ride. I have never had a bad experience there, even when the weather is bad. Solitude during the week, and I usually see someone I know when I go on the...More

Two challenges that face people that want to kayak on a river is the proximity to home and the logistics of being dropped off or picked up. For me, paddling on the Meramec River and using Castlewood State Park as a launch point solves both...More

I've seen many people play in the river but I do not let my children swim or wade in the Meramec. It is dangerous because of the undertow that will drag you under . Between 2004 and 2016, twelve people drowned.

I believe it’s the one on Left as you come into the park about 1/2 mike from the visitor center. Stop at the building at the entrance and there are maps of the park.
