Iowa trails · Lake Loop
A 4.7-mile network in Iowa, with 55 ft of climbing. Reaches Red Haw Lake. Managed by the state.
Most of the climbing sits in the final third — 61% of the ascent, between mile 5.2 and mile 7.8. It gives back about 169 ft along the way, so it rolls rather than climbing steadily.
