Route Briefing: Dublin to Reykjavik
Just over three hours from Dublin and you're stepping off the plane into one of the most otherworldly places on Earth — that's the quiet magic of this route. Icelandair and Aer Lingus both serve it year-round, and when fares dip below $250 roundtrip, it's genuinely one of Europe's great travel bargains for the distance and experience you get.
Keflavík International Airport sits about 50 kilometres southwest of Reykjavik, and the Flybus coach service connects the two reliably, dropping passengers at the main bus terminal in the city centre. It's a straightforward, well-worn journey that travellers have been making for decades.
Reykjavik itself is compact, walkable, and utterly unlike anywhere else. As the world's northernmost capital, it carries a certain quiet pride in its strangeness — colourful corrugated-iron houses, steaming geothermal pools, and a food scene that leans hard into lamb, skyr, and fresh North Atlantic seafood. The city is a base rather than the whole story, though. The Golden Circle route loops you through geysers, the Þingvellir National Park rift valley, and Gullfoss waterfall — all within a day trip. The Blue Lagoon geothermal spa, closer to the airport than the city, is worth booking well in advance regardless of when you travel.
Timing matters enormously here. Summer — June through August — brings the midnight sun, hiking season, and the best conditions for road trips along the Ring Road. It's also peak season, so flights and accommodation cost more and should be booked two to four months ahead. If the Northern Lights are your reason for coming, you need darkness, which means travelling between roughly September and March. The shoulder months of April to May and September to October offer a genuine sweet spot: cheaper fares, fewer crowds, and a reasonable shot at aurora sightings as the nights lengthen again.
The one tip worth burning into your memory: geothermal swimming pools are everywhere in Iceland, and the local neighbourhood pools used by Reykjavik residents are dramatically cheaper than the famous tourist spas. They're also a far more authentic slice of daily Icelandic life — locals soak, chat, and decompress in them year-round, rain or shine. Pack a swimsuit in your carry-on and make it your first evening ritual after landing.
From Dublin, this is one of those routes where the destination genuinely justifies every cent of the fare.
