Samantha, Exactly what Timothy said! A quick way to check is on our website under "Park Postings" on the right hand side: http://www.stlouisco.com/Parks-and-Recreation
The park is open but the 5 mile loop and 1/2 mile loop are closed.
I was there yesterday. Some of the trails were closed, but most were still open. I was able to do over 3 miles.
