Titanic attractions

Voted the world’s best region to visit in 2024 / 2025 by travel guides, Belfast is teeming with Irish pubs, hip restaurants, boutique hotels and concert venues.

On the road

Cheap flights to Belfast can open up a whole world of geological and cultural marvels.
Get out of the city and hit the Causeway Coast for Game of Thrones locations and UNESCO World Heritage Site the Giant's Causeway, made up of 40,000 basalt columns.

When to go

The best time of the year to visit is April to September – officially British Summer Time. This is when the days are longest, temperatures are highest, reaching a peak of 15 degrees Celsius in July, and Mother Nature is at her most enticing. You’ll find crowds drinking Guinness in beer gardens or relaxing in the parks, and there’s the annual community festival Féile an Phobail in August.

For lovers of the great outdoors, autumn and winter can be a magical for return flights to Belfast, and since it’s low season you’re more likely to find great deals on last minute flights. Check out the Gruffalo Trail at Colin Glen Forest, where you’ll come face-to-face with an eight-metre-tall Gruffalo, or strike out for the Belfast Hills with their jaw-dropping scenery.

Whatever month you decide to travel, the weather can be erratic and rainfall is one thing you always have to consider when booking flights to Belfast, so packing an umbrella is never a bad idea.
