Reykjavík from Oslo: Best Things to Do & Where to Stay

Reykjavík is one of the easiest escapes from Oslo that still feels like a different world: a three-hour flight drops you in a small, walkable capital surrounded by lava fields, geysers and geothermal pools. For anyone based in the Nordics it works perfectly as a long weekend, since you skip the long-haul fatigue that puts other travellers off. This guide covers the flight, the ten experiences worth your time, the best neighbourhoods to base yourself, and how to handle Iceland's famously high prices.

Getting there from Oslo

The headline news is good: you can fly direct from Oslo to Reykjavík. Icelandair operates non-stop flights between Oslo Airport (OSL) at Gardermoen and Keflavík International Airport (KEF) year-round, and Scandinavian Airlines (SAS) and Norwegian add seasonal service on the same route. The flight takes roughly three hours, which makes a Friday-evening departure and Monday return very doable. Frequency is higher in the summer peak than in deep winter, so check the airline websites for current schedules and fares rather than assuming a daily flight.

A practical note that surprises first-timers: because both Norway and Iceland are in the Schengen Area, the trip is treated like a domestic arrival, so there are no border queues on the Icelandic side beyond a quick passport check. Keep your residence card or passport handy regardless.

Keflavík airport sits about 50 km southwest of Reykjavík, on the Reykjanes peninsula, so factor in transfer time. The simplest option is the Flybus coach, which leaves shortly after each flight lands and reaches the BSÍ bus terminal in the centre in around 45 minutes; buses wait for delayed flights and have luggage space and WiFi. A Flybus+ ticket continues from BSÍ to many hotels and guesthouses in a minibus. Buy online in advance, at the airport machines, or at the counter in arrivals. Pre-booked private transfers and rental cars are also widely available — a car makes sense if you plan to self-drive the Golden Circle, less so if you are staying central and joining tours. There is no airport train or metro.

The best things to do in Reykjavík

For a capital of under 140,000 people, Reykjavík packs in a lot, and most of the city sights are within walking distance of each other. Here are ten well-established experiences to build a trip around.

Hallgrímskirkja is the landmark you will recognise from every postcard — a 74-metre concrete church whose stepped facade echoes Iceland's basalt columns. Ride the lift up the tower for the best panorama of the colourful rooftops and the bay beyond.

Harpa Concert Hall sits on the waterfront, its glass facade modelled on Iceland's basalt and the play of northern light. Even if you are not seeing a concert, step inside to see the honeycomb of coloured glass, and it is free to wander the lobby.

The Sun Voyager (Sólfar), a steel sculpture resembling a Viking longship, stands on the seafront promenade a short walk from Harpa. It is a quick stop but a classic photo, especially when the low sun reflects off the water and the mountain Esja across the bay.

Perlan sits on Öskjuhlíð hill and is built atop the city's hot-water storage tanks. Its glass dome houses the "Wonders of Iceland" exhibition, including a real ice cave and a planetarium-style aurora show, and the wrap-around observation deck gives a 360-degree view of the city and coast — handy on a cloudy day when you still want a viewpoint.

Laugavegur is the main shopping and going-out street, one of the oldest in the city, lined with Icelandic design shops, wool stores, bookshops, bars and restaurants. Wandering it is the best way to feel the rhythm of downtown Reykjavík.

The Old Harbour (Gamla höfnin) is the departure point for boat trips and home to seafood spots and small museums. From here, whale-watching tours head into Faxaflói Bay in summer, where minke and humpback whales, white-beaked dolphins and harbour porpoises feed; operators report sightings on the large majority of summer sailings.

A short bus or taxi ride from the centre, Nauthólsvík geothermal beach mixes warm geothermal water into a sheltered cove of golden sand, with hot tubs on the shore — a genuinely unusual swim by the Atlantic. Iceland's pool culture is central to daily life, so a visit to any of the city's geothermally heated public swimming pools is one of the most local things you can do.

Two flagship day trips bookend most Reykjavík breaks. The Golden Circle is a roughly 250-km loop that takes in Þingvellir National Park (a UNESCO site where the Atlantic and North American tectonic plates pull apart, and the birthplace of Iceland's parliament), the Geysir geothermal area where the Strokkur spout erupts every few minutes, and the thundering two-tier Gullfoss waterfall. It is easily done in a day by tour bus or rental car.

The Blue Lagoon, a milky-blue geothermal spa set in a black lava field near Keflavík, is Iceland's most famous bathing experience and conveniently positioned between the airport and the city — many visitors stop there on the way in or out. It is ticketed and must be pre-booked with timed entry, so reserve before you fly and check the official site for current prices and any closures, as the nearby Reykjanes volcanic activity has affected access in recent years.

Where to stay

Reykjavík is compact, so most visitors stay in or near the centre and walk. Choose a neighbourhood by how lively you want your evenings.

Downtown / Miðborg is the heart of the action, around Laugavegur and Skólavörðustígur (the street that runs up to Hallgrímskirkja). You are steps from restaurants, bars, museums and the harbour, which suits first-timers and short stays. Trade-offs are higher prices and some weekend nightlife noise.

Old Harbour and Grandi is the regenerated waterfront just west of the centre, with design studios, the maritime museum, cafés and the whale-watching docks. It is calmer than the main drag but still walkable, good for travellers who want character without the late-night buzz.

Laugardalur, a few kilometres east, is a greener, residential area around the city's largest swimming pool, botanic garden and the campsite/hostel cluster. It suits budget travellers, families and anyone with a rental car who wants quieter, often cheaper rooms, with an easy bus into town.

Hlemmur and the eastern end of Laugavegur strike a middle ground — close enough to walk into the centre, near the Hlemmur food hall, and usually a little gentler on the wallet than the prime downtown blocks. Use the site's Booking.com search below for live availability and prices in each of these areas rather than fixating on a single hotel.

When to go

There is no single best season — it depends on whether you are chasing the northern lights or the midnight sun.

For the aurora, aim for late September to early April, when nights are long and dark enough; the strongest window is November to March. You still need clear skies and a bit of luck, so build in a few nights and consider an evening tour that drives away from city light pollution. Winter days are short and the weather is changeable, but the city is atmospheric and quieter.

For long days and easy travel, come in June and July. The midnight sun keeps the sky bright almost around the clock, temperatures are mild (though rarely warm), whale-watching is at its best, and the Golden Circle roads are at their most reliable. The flip side is peak prices, busier sights and no chance of aurora. May and September are excellent shoulder months — fewer crowds, softer prices, and September even offers early aurora chances alongside still-decent daylight.

Whatever the season, pack for wind and sudden rain. Icelandic weather turns fast, and a waterproof layer matters more than a thick coat.

Budget and practical tips

Be honest with yourself before booking: Iceland is expensive, often more so than Norway, especially for eating and drinking out. Coming from Oslo you are already used to high prices, which softens the shock, but a restaurant dinner with a drink, museum tickets and a Golden Circle tour add up quickly. The currency is the Icelandic króna (ISK), and Iceland is almost entirely cashless — you can use a card for everything from a hot dog to the Flybus, so you rarely need to withdraw cash.

A money tip: foreign-currency and travel cards such as Revolut, Wise or your regular Nordic bank card all work fine, but watch the exchange rate and any foreign-transaction fees your home bank charges. A multi-currency card that converts at the interbank rate can quietly save you a meaningful amount over a long weekend of card taps.

Getting around the city itself is cheap and easy on foot; the central sights are clustered, and the Strætó city buses cover the rest. You only really need a car or tours for the Golden Circle, Blue Lagoon and the South Coast. Tap water is excellent and free, so carry a bottle rather than buying water. Tipping is not expected. And because the trip mixes glacial rivers, hot springs and changeable weather, decent travel insurance that covers active excursions is worth sorting before you fly.

Good to know

Reykjavík rewards a little planning. Pre-book the things that sell out — the Blue Lagoon with a timed slot, any whale-watching or Golden Circle tour in peak season, and your Flybus transfer. Build your itinerary around the weather forecast rather than a fixed plan, since Icelanders themselves adjust constantly. Three to four days is plenty for the city plus one or two big day trips; resist trying to ring-road the whole island on a short break. With a direct three-hour flight from Oslo, a cashless card in your pocket and a waterproof in your bag, Iceland's capital is one of the most rewarding short escapes in the Nordic neighbourhood.
