Meath County Council is being urged to improve roads in the area.
Fianna Fáil is calling for the council to go "back to basics" to ensure the road network is "up to scratch".
Senator Thomas Byrne said: "I raised this issue in a recent meeting with the County Manager in Navan, that it was all very well having a tourist strategy, but if the road network wasn't up to scratch, then we were wasting our time.
"The condition of the roads in Dowth and Newgrange in particular has been nothing short of embarrassing with thousands of foreign tourists literally expected to bump along on potholed roads to visit globally important passage tombs and megalithic art.
"I also understand from sources in the OPW that the state of the roads is having an adverse effect on their buses used to transport tourists from Brú Na Boinne to the monuments."
