Cal-Sag Trail and Centennial Trail

Both the Cal-Sag Trail and the Centennial Trail are primarily paved and largely flat, making them suitable for road cycling. The Cal-Sag Trail is a multi-use path, mostly smooth, though some sections east of 86th Avenue can be more hilly and densely tree-lined. The Centennial Trail is paved asphalt, generally in excellent condition, with only minor inclines. Be aware that a short segment around Lemont on the Centennial Trail has older blacktop, and some industrial access road sections may have dust and truck traffic, especially on weekdays.

The trails offer diverse scenery. On the Cal-Sag Trail, you'll find pleasant waterway views along the Cal-Sag Channel, shaded forests, and natural areas like the Sag Quarries Nature Preserve. The Lake Katherine area is particularly scenic. The Centennial Trail follows the Des Plaines River, featuring woodlands, natural preserves, and a historic swing bridge. You can also see the Centennial Trail itself and the Saganashkee Slough.

Yes, both trails are generally considered easy to moderate due to their mostly flat, paved surfaces. This makes them very suitable for beginners and families cycling with kids. The Cal-Sag Trail is designed to minimize road crossings, often directing cyclists under roadways for a more continuous and safer experience.

The trails can be enjoyed throughout the warmer months. Spring and fall offer pleasant temperatures and beautiful foliage. Summer is also great, though some sections may be less shaded. Always check local weather conditions before heading out.

Trailheads along both the Cal-Sag Trail and Centennial Trail offer parking. For example, the Schneider's Passage Entrance is a known access point for the Centennial Trail near Romeoville Prairie Nature Preserve.

This creates over 100 miles of connected trails in the Chicago Southland area, including sections of the Illinois and Michigan Canal Trail and the Sag Valley Trail System.

While the trail research doesn't specify cafes or restrooms directly on the trails, some trailheads offer amenities such as bike tools and pumps.
