Follow the coast road north from Trébeurden and take the left turn to Île Grande and if you follow the lane to the village turn right where there is a sign to the Dolmen campsite then a left signed to the dolmen itself. You will come to the site after a while on the left.
This tomb is in good condition and some of the mound is still visible. The long chamber is 9 by 1.5m (30 by 5ft) and two large capstones are held up by the two rows of support stones that are about 1m high. The stones are granite and several smaller kerbstones surround the site.
