There are a slew of excellent and rather underrated European destinations you can fly to for cheap from Dublin Airport.
Bratislava is the capital of Slovakia and is rather small compared to other close-by European cities like Budapest and Vienna. Home to some unique culture, fascinating history and perhaps most importantly, great food and drink, Bratislava is cheap to get to from Dublin Airport and will make for a wonderful few days away.
Flights to Bratislava from Dublin Airport with Ryanair are some of the cheapest going starting at just €21.99. With it being such a small city (of under 500,000), you don't need a huge amount of time to spend here. A weekend or even a couple of days midweek would be more than enough to see the top rated attractions and enjoy some great dining experiences.
