According to the United States Census Bureau, the borough has a total area of 1.2 square miles (3.1 km2), all of it land.
The borough is located along Pennsylvania's Bucktail State Park Natural Area, also known as Pennsylvania Route 120, which winds through the surrounding mountains following the West Branch Susquehanna River. The town is also the home of the "Flaming Foliage Festival" held each October, generally in the second weekend, that celebrates the glorious fall colors of the area's mountains. The festival includes a parade, a queen is chosen (usually from one of the nearby high schools) and crowned. The festival serves as a 'homecoming' event for former residents of Renovo, many of whom return annually for the event.
