PA 93 begins at an intersection with US 209 in the borough of Nesquehoning in Carbon County, heading north on two-lane undivided Hunter Street. The road passes over a railroad line owned by the Carbon & Schuylkill Railroad and operated as part of the Reading Blue Mountain and Northern Railroad's Reading Division before it heads into forested areas. The route begins to ascend Broad Mountain, gaining a second northbound lane and curving northeast, where it comes to a southbound runaway truck ramp. PA 93 narrows back to two lanes and curves north and then west as it continues to climb the mountain. The road turns to the northwest and heads through dense forested areas on Broad Mountain, reaching a southbound truck brake check station. The route crosses into Packer Township and descends the mountain to reach the community of Hudsondale, where SR 4010 (Brenkman Drive) and SR 4006 (Packer Drive) both head northeast toward the borough of Weatherly. PA 93 heads through wooded areas with some fields and homes before it curves west and crosses forested Spring Mountain, where it enters Banks Township. After crossing the mountain, the road intersects SR 4006 (Spring Mountain Road), which heads east to Weatherly. The route heads into the borough of Beaver Meadows and becomes Broad Street, passing homes and a few businesses. PA 93 turns northwest onto Berwick Street and runs through more developed areas of the borough. The route leaves Beaver Meadows for Banks Township again and becomes Main Street, passing through wooded areas and the community of Coxes Village as it heads to the northeast of a coal mine.
