The Elroy-Sparta State Trail is Sparta's defining attraction. Opened in 1967 on a former railroad line, it helped prove that abandoned rail corridors could become long-distance recreation routes.
The ride runs 32 miles through farms, woods, limestone cuts, trestles, and three tunnels. Bring lights for the tunnels and expect a surface better suited to hybrid, touring, or gravel bikes than skinny road tires.
