I've ridden about 1,500 miles of trails in Ohio but hadn't ridden the Celina-Coldwater Trail yet so I drove over from Columbus to ride it. Overall I would call this a very good trail.
There is no dedicated parking at either end of this short 4.7-mile paved trail. The best place to park near the trailhead in Coldwater is in the gravel parking lot of a small industry located at the intersection of East Vine Street and North 4th Street, which is at 40-28.916N and 084-37.579W. Others park along the curb nearby. The trailhead is located at 40-29.012N and 084-37.572W. All of the roads in this area run north-south or east-west while the trail runs northeast from Coldwater to Celina so it crosses several roads along the way at angles. There is no nearby parking in Celina, which is why I suggest parking in Coldwater.
Once in Celina at the terminus located at 40-32.293N and 084-34.578W, it is a very short ride of about 0.2 miles over to Grand Lake St. Mary's up a slight grade to reach West Bank Road. The lake is actually slightly above the trailhead so it isn't visible from the end of the trail but just ride due east and you'll reach it in about three minutes. West Bank Road is a very slow-paced road that is suitable for riding. Turn south and you will arrive in Grand Lake St. Mary's State Park in about five minutes. Turning north will be a 10-minute ride into downtown Celina where there are various eateries along the route. If you're going to ride the trail, then I strongly suggest making the side trip over to and along West Bank Road. It's very scenic and the spillway is particularly impressive.
Although the trail is well-signed and maintained, my overall evaluation is only a very good or three star due to the short length and the absence of designated parking.
