The Algonquin Road Trail and Paul Douglas Forest Preserve Trail combine to completely encircle the large forest preserve in northwestern Cook County. The paved trail provides access to many of the preserve’s facilities, as well as the communities northwest of the park.
In the north, the trail parallels Algonquin Road, occupying the north side of the busy street between S. Roselle Road and S. Ela Road and the south side for the remaining length. The southern portion of the loop within the Paul Douglas Forest Preserve features gentle, rolling hills and is generally quiet—a nice respite from much of the rest of densely populated Cook County.
In the west, the trail continues from the intersection of Algonquin Road and Huntington Boulevard to the entrance for the Crabtree Nature Center. The preserved landscape is popular with birdwatchers and also offers an extensive network of hiking trails.
At S. Roselle Road, the pathway meets the Palatine Trail, offering cyclists and pedestrians direct off-road access to Harper College, the Deer Grove East Forest Preserve and a variety of parks and other amenities in the Village of Palatine.
Parking for the Algonquin Road Trail/Paul Douglas Forest Preserve Trail can be found at the entrance to the Crabtree Nature Center on the south side of W. Palatine Road. Parking is also available at the entrance to the Paul Douglas Forest Preserve off W. Central Road (east of Huntington Boulevard).
