The Saganashkee Slough – Centennial Trail loop from Midlothian is a challenging road cycling adventure that blends urban pathways with surprising natural beauty. You'll pedal along the paved Centennial Trail, tracing the Des Plaines River and Chicago Sanitary and Ship Canal, before encountering the serene, wooded landscapes around Saganashkee Slough. Be ready for varied terrain, as this route includes a significant unpaved section near the slough, making it a true test for road bikes.
This difficult 89.5-mile (144.0 km) loop, with 966 feet (295 metres) of elevation gain, is estimated to take 6 hours and 32 minutes. It's crucial to be prepared for mixed surfaces; while much of the Centennial Trail is paved, the unpaved sections around Saganashkee Slough are more suited for a gravel or mountain bike. Consider visiting in spring or fall for prime birdwatching opportunities, as the slough is a known spot for migratory birds.
This route is a key part of a larger network, connecting to other significant trails like the Cal-Sag Trail and the I&M Canal Trail, offering extensive long-distance riding options. The Centennial Trail itself follows a historic strip of land, featuring a historic swing bridge, and the Saganashkee Slough is recognized as an Urban Night Sky Place, providing a rare chance for stargazing near a major metropolitan area.
