Urban Decay that nature has reclaimed. This now island was once part of the Illinois shoreline. A canal was dug for water power to run the John Deere Plow Works. Former Republic Steel plant ruins are still eroding into the landscape. Trails snake thru the old foundations and around the perimeter of the island. A very unique place to bike and hike. Access was cut of in 2013 from the bridge being unsafe to cross. It was removed and a new one installed late 2017. Located near an old Moline neighborhood, many families have enjoyed the park and maintained it. QCFORC.org maintains the bike trails. ENJOY

Smells like a trash dump all over the island. There is a lot of building debris, and garbage on the island.

      Fun, varied trail/s with a lot of technical options. However, it's very confusing trying to find or stay on the main trail.

      Fun times but very difficult to follow the orange arrows pointing the right direction. Still haven’t figured out the entire path shown here.

      We hope you've been enjoying Trailforks!
