How do I find cheap train tickets from Killarney to Dublin?
If you’re planning a trip to Europe soon, our Trainline team of experts have put together some tips to help you find cheap tickets. Booking on the day in Europe is usually more expensive and costs can vary depending on the time of day, route or travel class.
1. Book in advance
The price of train tickets from Killarney to Dublin starts at £23.76§ one-way for a Standard Class ticket if you book in advance. Most train companies across Europe release their tickets around three to six months ahead of time, so if you know the dates you want to travel, you may be able to find cheaper tickets.
2. Be flexible with your travel times
If you can, consider travelling outside of 'peak hours' (generally between 06:00 - 10:00 and 15:00 - 19:00 on weekdays) as many train companies increase their ticket prices during these commuter times.
3. Buy a rail pass
If you're visiting multiple locations on your trip, buying a rail pass can be cheaper than buying individual tickets. We're official retailers of Interrail Passes that are valid for travel within one country or multiple countries across Europe.
4. Choose a slower or connecting train
On some busier routes, you might have the option to take a slower or connecting train. It may take longer than some high-speed or direct services, but if you have some extra time on your hands, you might find a cheaper fare.
5. Look out for train ticket sales and discounts
Many train companies in Europe will often run sales on tickets throughout the year or offer discounts to senior/youth/group travellers, so keep an eye out!
6. Take a night train
Save on accommodation and use the night to travel by sleeper train to your next destination.

On rare occasions, train companies may choose to release special offers closer to the date on last-minute or late-release tickets. This is dependent on the individual train operating company you travel with.
