Opened in 2015, this small but absorbing place has a museum detailing the megalithic wonders hereabouts, as well as a cafe (dishes €3 to €6), hostel (dorm beds €17) and campground (tent per person €10). Special events (eg solstices and equinoxes) take place throughout the year. Contact the centre about picking up the key for nearby Cairn T .
The centre is 20km west of Kells via the R154 and the L2800; you'll need your own wheels to get here.
