Ulster's most famous Stone Age monument is a strangely elegant tripod dolmen (tomb chamber), that looks as if a giant's hand has placed the capstone delicately atop the three slim uprights. Its elevated position on the western slopes of Slieve Croob (532m) gives it an impressive view to the Mourne Mountains.
Legananny is a challenge to find without the aid of a 1:50,000-scale map. Heading south from Ballynahinch along the B7 to Rathfriland, go through the hamlets of Dromara and Finnis, then look out for a minor road on the left (signposted Legananny Dolmen). Continue for a further 3km, through a crossroads, and look for another road on the left (a signpost is there, but it's difficult to spot). Continue over the hill for 2km, then turn left again at a farm. There's a parking place 50m along, and the dolmen is 50m uphill on the adjacent farm track.
