SR 185 is the main route into the center of Sorrento. It begins east of the downtown area at the intersection of Ocean Avenue and Keasarge Avenue on the south side of the peninsula. The route heads northeast for one block until reaching a four-way intersection with Waukeag Avenue and Doanes Point Avenue. At this point, SR 185 turns due north along Sorrent Avenue and parallelsBack Cove for about. At West Shore Road, SR 185 heads east along East SideRoad to cut across the Waukeag Neck peninsula to later parallel the shore of Flanders Bay. Through this area, the road passes a golf course and a church. Shortly after the northernmost intersection with West Shore Road, SR 185 ends at US 1 just past the Sorrento–Sullivan town line.
