Bringing your own car to Leitrim County is not advisable due to the high costs involved. Car rentals for tourists are an inescapable fact of life. Yes, you can live without them by taking the public transport but you will lose freedom of movement and will be at the mercy of the public transport driver's disposition with regard to stopping at beautiful places. Your own rented car allows you to stop anywhere for as long as you want and the prices are not too exorbitant either.
In County Leitrim, you can find established international car rental offices as well as many local businesses offering the same service. With so much variety, it is better not to get into the hassle of comparing prices and just take any car that meets your needs without any fancy extras causing an adverse effect on your wallet. It is highly recommended to ask for a high visibility waistcoat for the unfortunate scenario of your car breaking down. Most of the car rental offices are located in or near the major airports allowing international tourists to start their wonderful journey as soon as they step on Irish land.
