While renting a car can provide flexibility and convenience, it’s not necessary to explore Ireland. The country has an extensive public transportation network, including trains and buses, which can take you to most major towns and attractions. If you prefer not to drive, guided tours and day trips are also available, allowing you to explore popular destinations without the hassle of navigating the roads yourself. However, if you plan to venture off the beaten path or explore remote areas, renting a car can offer more freedom and access to hidden gems.
