In the past, I would have rated at a 5. In the past 3-4 yrs, the park has become so overrun with people that it’s no longer my peaceful place. The trails are too congested to really move. It makes me sad. Castle wood was...More

Castlewood is one of the most beautiful parks in the St. Louis region, especially the ridge trail overlooking the Meramec. A short but steep hike leads to the rocky ridge trail with a number of fantastic rocky overlooks. Gorgeous, especially in autumn! But as much...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

Even without having taken the bluff trail which has to be the most scenic, I can vouch for the lower trails which are great for hiking or mountain biking. You might think that the railroad tracks running through the park would take away from the...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.
