The eastern terminus of the nearly statewide Katy Trail is in Machens, a small village in St. Charles County. My friend and I walked from Black Walnut, where parking is available, to Machens, where there is no parking. Our walk was very wooded and buggy, and I had to wear my covid mask to keep from swallowing gnats. We saw many different types of birds along the way. The bathroom at Machens was locked. This end of the trail could use some TLC... and a parking lot. It's only worth visiting if you're interested in seeing the easternmost part of the trail because it's quite a drive to Black Walnut for a less scenic walk than is at Main Street, Fifth Street, or elsewhere on the trail. read more
