There is a four mile loop around the lake. It was classified as a hike in Hiking Iowa, but it really is more of a four mile walk on a mowed pathway.
We entertained ourselves by pretending that it was as difficult to hike as Ledges.
After crossing that hike off of our list we both agreed that when we only have time to do a quick hike we'll still head up to Ledges. It's only 30 min more round trip, and it is definitely worth it for the scenery and hiking.
