Cal-Sag Trail

Trail Map

Description Suggest an Edit

The Cal-Sag Trail (or, Calumet-Sag Trail) is currently under active construction. As of August 2015, it has a competed section of about 10 miles, stretching from near its eventual western terminus to Ridgeland Avenue in the east. When completed, the trail will stretch some 26 miles, mostly along the Cal-Sag Channel and Little Calumet River. It will connect several communities and other trails, and provide access to several forest preserves and natural areas.

Near its present western endpoint at the Sagawau Environmental Learning Center, the trail passes through the Sag Quarries Nature Preserve, where old stone quarries have been converted to lakes for birding, fishing and hiking. From there eastward, the trail is rather flat as it passes cleared expanses of forest land now landscaped with natural grasses and wildflowers.

On eastward, beyond the cutoff to Teason's Woods, the trail becomes more hilly and densely tree-lined, all the way to just east of the 86th Avenue parking area. There it comes away from the woods to run alongside Calumet Sag Road, all the way to Southwest Highway. For about two blocks the trail continues alongside the highway without crossing it, though some trail-goers may want to cross to one of the businesses there to get refreshment or food.

From highway to woods again, the trail rejoins its fundamental alignment next to the Channel. It goes under another roadway and a railroad bridge, before breaking onto a quiet city street around the beautiful Lake Katherine area. From there it's back to wooded trailway all the way to the end at Ridgeland Avenue.

Parking and Trail Access

There is parking on the completed trail at these four locations:

  • Sag Quarries, just west of Camp Sagawau near Lemont
  • Teason's Woods, 104th Ave south of IL-83, Palos Park
  • 86th Ave & IL-83, Palos Park
  • Lake Katherine, Palos Heights

Lake Katherine is the only area with restrooms and drinking fountains, as well.


Trail itself is great, needs better markings for west-end connection

My dad, brother, and I rode a few miles on the west end of this trail last weekend and it was great. Had to turn around because of rain but the short segment we did was in beautiful shape. My complaint is the connection at the west end of the trail. more

GREAT trail for us Southwest siders!

I have been riding this trail since July 2015 and each time out is a different and enjoyable experience. In the beginning I would park at 86th Ave or Southwest Highway and head west to the Cal Sag Quarries and back. Since the completion of the paving more

I'm sure it's even better in the summer

We did 12 miles each way on this today, it's supposed to be 13 miles (with plans to expand to 26 eventually?) but we couldn't see the connection for the last mile. The path has a fair number of small hills, all paved. It's lovely scenery, not a lot of more
