Mixed-use hiking & biking trails are extremely popular in PA. Many have been constructed upon the vestiges of abandoned railway lines. The Ephrata-Warwick trail is one of these.
I picked it from the map as a place to visit pretty much at random, other than noting that it crossed over some water, and that it would be a relatively casual/paved walk. I walked about five or six miles if I recall correctly. It was extremely popular when I visited. Which, to be fair, is probably what I get for visiting what Wikipedia calls "the most populous borough in Lancaster County" during a holiday weekend. This in and of itself isn't a bad thing, but I should note that I was the only person that I saw engaged in mask wearing. So, I kept my mask on at all times. There are actually a fair number of interesting and worthwhile sights along this trail. I'll let my photographs (mostly) speak for themselves.
