Consider renting a car to get to The Cliffs of Moher or booking a guided tour to ease the trip. Public transportation is widely available in Dublin and is the most convenient way to explore the city. Uber and taxi services are also available and priced comparably.
With more time, consider a trip to the charming city of Galway or the historic Blarney Castle to kiss the Blarney Stone. Alternatively, for a shorter trip, opt to just explore Dublin's city center - there are numerous museums, historic buildings, and gardens to explore.
The main airport in Dublin is Dublin Airport (DUB), located about 10km north of Dublin's city center. It offers frequent flights from various destinations in Europe, North America, and worldwide.
