begins at the midpoint of the Narrowsburg–Darbytown Bridge over the Delaware River as a county-maintained continuation of PA 652 (Beach Lake Highway). Co-designated as County Route 24 (CR 24), NY 52 proceeds southeast through the hamlet of Narrowsburg in the town of Tusten as the two-lane Bridge Street. After crossing over Norfolk Southern's Southern Tier Line, NY 52 and CR 24 pass St. Francis Xavier Cemetery and then leave the center of Narrowsburg, merging with NY 97 south of Feagles Lake. County maintenance ends at this point. The two routes soon bend eastward to a junction where NY 52 turns northward on a county-maintained roadway. Now co-designated as CR 111, NY 52 bends northeast through Tusten, remaining a two-lane rural roadway as it climbs slightly out of the river valley. The surrounding landscape is mostly forested, with occasional farm clearings. A mile from that junction, NY 52 and CR 111 reach the small hamlet of Lava, crossing the northern terminus of CR 25 (Eckes Road). Continuing northeast out of Lava, the two routes continue past Beaver Pond and then descend into the Tenmile River valley. A short distance later, NY 52 crosses into the town of Cochecton, where CR 111 terminates and NY 52 becomes concurrent with CR 112. NY 52 continues northeast through Cochecton, reaching the hamlet of Cochecton Center. After passing through, NY 52 and CR 112 turn straight northwest for through Cochecton at a junction with CR 115 (Browntown Road). At the second junction with Kelly Road, the route turns north for a half-mile (800 m), turning westward at Buff Road to reach the southern shore of Lake Huntington. The routes turn north along the western shore, entering the eponymous hamlet and reaching the eastern terminus of CR 116. At this junction, CR 112 ends, and NY 52 becomes maintained as CR 113. CR 113 and NY 52 turn northeast briefly along the northern shore of the lake, then leaving it and continuing northeast through Cochecton. Farms begin to break up the forest cover around the road more extensively here. At the junction with Shortcut Road, NY 52 turns to the north, reaching a junction in a half-mile with NY 17B and the eastern terminus of CR 114 (Newburgh Turnpike). At this junction, the small hamlet of Fosterdale, NY 17B turns north and joins NY 52, which becomes state-maintained again. The routes continue northward for , where
