This area is one of the nicest areas in southwestern PA near Pittsburgh. Ohiopyle and the Laurel Highlands both have lots of hiking, biking, and boating (canoeing / kayaking) options, and it's an especially beautiful area to visit in the fall. Laurel Hill specifically has a pretty large campground area with the standard site options, bathrooms with showers, and even a few different playgrounds. From the campground, you can walk to the Jones Mill Run Dam (built by the CCC) for a cool photo opp or hike the short Hemlock Trail to see some old growth forests. The Laurel Hill Creek and Lake are also within walking distance for fishing, trying to see salamanders, turtles, snakes, etc. Lots to do with the family.
