Arlington Wetlands

Welcome to Arlington Wetlands, a serene park and tourist attraction located on Arlington Drive in Pontoon Beach, Illinois. Nestled within an 83-acre remnant meander of the Mississippi River, Arlington Wetlands offers a unique natural retreat just minutes from Granite City.

Visitors can explore the site via a 1.5-mile unpaved walking trail that meanders across a floating boardwalk and through a beautiful sand prairie. While enjoying the scenic views and abundant wildlife, take advantage of the picnic tables and conveniently located trash receptacles throughout the park. Please note that no restrooms are available on-site.

Arlington Wetlands is open daily from sunrise to sunset, unless otherwise posted. Dogs are welcome but must be kept on a leash. Parking is available at the park's entrance. For the safety and preservation of the area, boating, swimming/wading, and fishing are not permitted.

This vital natural space plays a crucial role in stormwater storage, water purification, and providing a habitat for local wildlife. The park's preservation was made possible in 2011 through a collaborative effort led by HeartLands Conservancy, in partnership with Madison County government, the former Collinsville Area Recreation District, ConocoPhillips, The Illinois Clean Energy Community Foundation, and the US Fish & Wildlife Service.

To visit Arlington Wetlands, take the Horseshoe Lake Road exit west from I-255 toward Granite City, then turn north onto Arlington Drive. The wetlands will be on your left. Come and experience the tranquility and natural beauty that Arlington Wetlands has to offer.
