Iceland from the UK: Honest Costs, Best Flights & What's Worth It

Icelandair from Heathrow to Reykjavik Keflavik runs from around £89 one-way, though £130–£180 is more typical once you're searching in peak season or with any flexibility in your bags. They're the most established option, the service is decent, and the flight is about three hours. Worth knowing: Icelandair also does stopover deals if you want to tack on a night in Reykjavik en route to North America, which is a genuinely clever way to split the cost.

easyJet fly to Keflavik from Gatwick from around £79 one-way, and I've seen it dip to £54 in late September if you're fast enough. The catch is the usual easyJet bag fee situation. Add a cabin bag and hold luggage and you're looking at another £35–£50 on top, so always price that in before you get excited about a cheap fare.

Wizz Air operate from Luton to Keflavik, with one-way fares sometimes from £69, though £85–£110 is a more honest expectation. Wizz Air's included baggage allowance is minimal, a small personal item only, so factor in upgrade costs early. Luton is a faff from central London but the fares can undercut the others meaningfully if you book at the right time.

A four-day trip to Iceland will cost most people £800–£1,200 per person all-in, and that's not being dramatic. Flights, a guesthouse or mid-range hotel in or near Reykjavik, food, a car hire, fuel, and one or two paid attractions will eat through your budget faster than almost anywhere else in Europe. When I went in October, a bowl of lamb soup and a coffee in a Reykjavik café cost me £22. That's just how it is.

Car hire is almost non-negotiable if you want to see anything beyond the capital. Expect to pay £60–£100 per day for a standard car in summer, more in winter when you'll need a 4x4 for certain highland roads. Fuel is expensive too, around £1.80–£2.00 per litre equivalent when I last filled up there. Don't go hoping to wing it on a tight budget.

Food is the other real drain. A sit-down dinner for two with drinks will rarely come in under £80, even at a mid-range place. Self-catering helps a lot. Supermarkets like Krónan or Bónus exist, and buying lunch and breakfast supplies there saves serious money over five or six days. Going full self-catering for two meals a day can cut £150–£200 off your total spend across a short trip.

The Golden Circle is genuinely worth it and you can drive it yourself in a day without a guide. Geysir erupts every few minutes, Gullfoss is one of the more dramatic waterfalls you'll see anywhere, and Þingvellir National Park is where you can walk between the Eurasian and North American tectonic plates, which is as strange and brilliant as it sounds. Skip the expensive coach tours and just hire a car.

The Blue Lagoon costs around £60–£80 per person for standard entry and needs booking weeks in advance. Personally, I reckon it's overpriced and overrun with tourists, and the water genuinely smells strongly of sulphur. The Sky Lagoon near Reykjavik is around £45 entry, less crowded, and arguably a better experience. Your money, your call.

If you're going in summer, the Snæfellsnes Peninsula is worth the two-hour drive from Reykjavik. Glacier, lava fields, fishing villages, the lot. In winter, spend your energy on getting away from city light pollution and hunting the Northern Lights rather than cramming in too many sights. Trying to do everything on a four-day trip leaves you exhausted and underwhelmingly half-doing each thing.

The Northern Lights require three things: darkness, clear skies, and solar activity. That means September through March only, away from Reykjavik's light pollution, and with weather that cooperates. When I went in October I drove 45 minutes east of the city, got lucky with a clear night and KP index of 3, and saw a proper green display. The night before was completely clouded over. You cannot book the Northern Lights. You can only put yourself in the right position and hope.

Summer has its own pull entirely. Flying from Gatwick on easyJet in late June for around £95 one-way, you get 24-hour daylight, roads that are actually all open, and temperatures around 10–14°C. Hiking, whale watching from Reykjavik harbour at around £65 per person, and the sheer weirdness of the midnight sun are all worth experiencing. Just don't expect it to be warm in a conventional sense.

The Ring Road, the 1,332km route circling the whole island, is not realistic on a short trip unless you want to do nothing but drive. On a four-day trip you'll cover a fraction of it properly, and rushing it to say you've done it is a waste. A focused southern coast route, waterfall to glacier to black sand beach, is far more satisfying than ticking off the full circuit badly.

So is it worth the money? Genuinely, yes, if you go in with clear eyes. Nowhere else in Europe gives you a glacier, a geyser, a volcanic landscape, and the possibility of the Northern Lights within an hour of landing. It's expensive because it's extraordinary. Just don't go skint and expect to enjoy it.
