Access to Newgrange is by guided tour only. Tours begin at the Brú na Bóinne Visitor Centre from which visitors are taken to the site in groups. Current-day visitors to Newgrange are treated to a guided tour and an re-enactment of the Winter Solstice experience through the use of high-powered electric lights situated within the tomb. The finale of a Newgrange tour results in every visitor standing inside the tomb where the tour guide then turns off the lights, and then turns on ones simulating the sunlight that would appear on the winter solstice.
