I was unable to find the trail at creve coeur lake park. I went in on marine, and parked at the first parking lot you come to, on the left. I rode up the trail to the boat launch place, then back to the highway over the trail. Then back, and on the grass around the perimeter of the disc golf field. Then, all the way around the lake. I'd read it was near some tennis courts, but I never found any tennis courts. I did get in 6.5 miles, but not on trails like I'd wanted. I was out of time and had to leave. On the way out, I went into the park entrance off of dorsett (just before marine), and drove around in there. No tennis courts. no trail that I could see. I was really disappointed. It sounded like a good ride to ride that trail, then across to katy trail and to bangert island trail (when it dries out).
I guess there are no signs, and it's definitely not on the park map (none of the ones I looked at). Any clues to where the entrance is (besides tennis courts- never found any of those, although they are on the park map)
