Need to include the beautiful flower arrangements at either end [planted every year by volunteers]. Also, the railroad depot that used to sit on the now non-existent tracks [is now] in Coldwater's park at the northeast corner and has been completely renovated. It is 3 blocks to the west of the south end of the bike path.
It's better to start at Celina on windy days, which happens often, because when you are riding back to Celina you will have the wind at your back instead of in your face.
My family went on the Celina to Coldwater Trail this year. The cracks have been sealed. It is fine for bicycles, however it's pretty rough for those rollerblading.
