1,800-acre state park on the Meramec River with top-rated hiking & mountain-biking trails.
“The best hiking and mountain biking within a short drive of the city, hands down. The bluff-top overlook of the Meramec River valley is worth the climb every single time. Muddy trails, big views, and the feeling of actually getting out of town. Go.”
