Citywest is conveniently located adjacent to the N7, with access via a grade separated interchange, just two miles from the M50 orbital motorway and a thirty minute drive from the airport or city centre. The N82 runs through the campus linking the N7 to the N81 serving Tallaght a major suburb of the city.

Public transport is excellent with three Dublin Bus routes (50, 65B & 69) serving the campus from the city centre approximately every fifteen minutes. 

In addition the campus is served by another three Dublin Bus feeder services to Tallaght Town Centre (a major public transport hub) and other suburbs.

The Luas light rail system serves Tallaght initially and ultimately Citywest.
