In addition to baseball diamonds, fishing, a playground, and a beautiful creek to play in, Warren Townsend Park has nature trails. This is a picture of the nature trail that is illustrated in this link. By the way, if you have dogs they are permitted on the trail as long as they are leashed.
This creek is located in Warren Townsend Park in Cannonsburg. When I happened upon the creek children were laughing and playing in the water. But by the time I got set up, they had moved on to run across the nearby bridge. A lot of couples get married here too.
