The route begins at an unsignalized T-intersection with SR 138 in northern Paint Township.

SR 771 heads north-northwest through first lightly wooded areas transitioning to farmland as it enters Fairfield Township.

The elevation of the route remains relatively flat except when it dips slightly to cross the Hardin Creek in Fairfield Township.

North of the creek, SR 771 enters the village limits of Leesburg and passes the Fairfield High School.

As the route enters downtown Leesburg, it passes through residential neighborhoods and light industrial facilities.
