Follow the Upper Lake lakeshore path southwest of the car park until you come to the considerable remains of Reefert Church above the tiny River Poulanass. It's a small, plain, 11th-century Romanesque nave-and-chancel church with some reassembled arches and walls. Traditionally, Reefert (literally 'Royal Burial Place') was the burial site of the chiefs of the local O'Toole family. The surrounding graveyard contains a number of rough stone crosses and slabs, most made of shiny mica schist.
