Belfast to Bru na Boinne

I assume you mean without a rental car. Rick recommends this private tour company: http://newgrangetours.com/. Otherwise, you can take a train to Drogheda and taxi from there; see also p. 122 of Rick's Ireland 2018 or www.irishrail.ie.

Thanks for your reply. Yes,without a car. Are there tour options from Belfast? Are there places to stay near by the visitor center?

Sorry Laura for my error. Since you brought up travel tours from Dublin and I was asking about travel from Belfast, I thought our discussion could include near by lodging and getting to the visitor center.
