Iowa trails · Rock Creek Lake Trail
A 7.6-mile network in Iowa, with 121 ft of climbing. Reaches Rock Creek Lake. Managed by the state.
The climbing leans toward the middle third: 46% of the ascent falls between mile 2.5 and mile 5.1. It gives back about 501 ft along the way, so it rolls rather than climbing steadily.
