You'll start on smooth, paved paths, enjoying views of the Raccoon River and crossing a rustic trestle bridge, before diving into the natural singletrack of Greenwood Park.

This moderate 7.7-mile (12.3 km) route, with 172 feet (53 metres) of elevation gain, typically takes around 3 hours and 9 minutes.

The area offers over 4 miles of moderate hiking trails, including the Gateway Trail (0.5 miles), Preparation Loop (0.5 miles), Wilderness Loop (1.4 miles), and North Loop (2 miles).
