The Clear Lake and Mason City Trails include the 7.5 mile Trolley Trail plus three trails in and around Mason City. The Trolley Trail, with trail heads in Clear Lake and Mason City, is mostly rural landscape.
In Clear Lake, the Iowa Trolley Park features a museum that is open on weekends during the summer months, which is an interesting visit for rail history buffs. Riders beginning at this end of the trail will then head north and then west, over small ponds including the aptly named Big Blue, which is great for fishing or swimming. Upon reaching Mason City, riders will arrive in the 81 acre Lester Milligan Park, which features many outdoor amenities and activities as well as rest room facilities. Circling the park is a small network of trails that tour Mason City.
