Hiking

The Duff Park Outer Loop offers a delightful mix of terrain, from the flat, paved Funk Bikeway along Turtle Creek to hilly single-track sections that climb through a designated Wild Plant Sanctuary. You'll traverse woodlands, discover vibrant native wildflowers in spring, and experience a rare old-growth forest, all within a moderate 3.2-mile (5.1 km) hike. With 428 feet (131 metres) of elevation gain, it's a rewarding route that takes about 1 hour and 29 minutes to complete, perfect for those seeking diverse natural beauty.

Planning your visit is straightforward, with a large parking lot, restrooms, and picnic tables conveniently located near the trailhead. The trails are dog-friendly, requiring leashes, and you should be prepared for some muddy sections, especially near the creek after rain. This route also connects to other paths like the Westmoreland Heritage Trail, offering options for extending your outing if you wish.

Duff Park holds a special distinction as a Wild Plant Sanctuary by the Pennsylvania Department of Conservation and Natural Resources, and it contains one of the last remaining old-growth forests in Pennsylvania. Interpretive signs along the way help you identify trees and learn about the local flora and fauna. This makes the Duff Park Outer Loop more than just a hike; it's an immersive natural experience right in Murrysville.
