The Jack A. Markell Trail offers a fascinating journey through Delaware's diverse landscapes, transforming a former freight rail line into a 17.5-mile (28.2 km) hiking route. You'll traverse elevated boardwalks over marshy wetlands, offering incredible views and wildlife spotting opportunities, particularly around the Russell W. Peterson Urban Wildlife Refuge. Despite its difficult rating due to length, the trail's 188 feet (57 metres) of elevation gain is minimal, making it a long but generally accessible walk that takes around 7 hours and 8 minutes to complete.

For your visit, the trail is predominantly paved and well-maintained, connecting Wilmington's Riverfront to Historic New Castle. While generally easygoing, remember to bring a light for the two tunnels under I-295 and Route 13, as they can be dark. Parking is available at various access points, and the DuPont Environmental Education Center is a good starting point with facilities. This trail is comfortable for a long day out, but always check local conditions before you go.
