Two days out, one day in, two days out, and a spare day
Five Days in South Iceland: What the Extra Two Days Buy You
Three days in the south is a trip of decisions. Golden Circle or south coast. Reykjadalur or Gullfoss. Something always comes off the list.
Five days is a different proposition, and not because it is three days with two more of the same bolted on. Five days removes the rationing. It unlocks two or three things three days cannot reach. And it gives you the one thing every Icelandic itinerary needs and almost none include.
A spare day.
Five days in South Iceland covers the Golden Circle, a full day on the south coast, one longer trip such as Þórsmörk in summer or Þjórsárdalur inland, one still day with no driving, and a spare day held back for weather. All of it works from a single base near Selfoss.
The shape
Two days out, one day in, two days out. That rhythm matters more than the order.
The mistake in a five-day trip is treating it as five consecutive days of driving. By the fourth morning that stops being a holiday. A still day in the middle is not a wasted day. It is what makes days four and five enjoyable rather than endured.
All of it works from one base near Selfoss, such as 360 Hotel Boutique & Spa. An hour from the Golden Circle one way, an hour from the south coast the other. Five days is also long enough that moving hotels starts to look tempting. Resist it. Checking out and checking in costs most of a morning each time, and on this route it buys you nothing.
Day one: the Golden Circle, slowly
Þingvellir first, and walk it. The rift path between the North American and Eurasian plates takes forty minutes at minimum. People who drive to the viewing platform, photograph it and leave have been to a car park above Þingvellir. Not to Þingvellir.
Geysir wants twenty minutes and no more, because Strokkur erupts every few minutes and the rest of the field is small. Gullfoss deserves twenty and both levels. Most people see one.
Lunch at Friðheimar, inside a working tomato greenhouse, open year round. Book a table first.
Back for the evening. The spa at 360 Hotel Boutique & Spa is included in the room rate and open until nine. After a day standing in wind, that is worth more than it sounds on paper. Dinner at Hnaus by Hinrik Lárusson, who was named Icelandic Chef of the Year in 2024.
Day two: the south coast, properly
This is the long day, and five days is what lets you do it without sprinting.
Seljalandsfoss is about an hour east. Walk the extra few minutes north along the cliff to Gljúfrabúi, hidden in a rock cleft you wade into. Forty meters of waterfall in a chamber of its own. Almost nobody does, because the famous one next door absorbs everyone who parks.
Skógafoss beyond that. Sólheimajökull is the easiest place on this coast to stand on a glacier. It is gray and ash-streaked rather than the blue ice of the photographs. Worth knowing before you arrive.
Reynisfjara and Vík are up to two hours each way at the furthest point. Reynisfjara is genuinely dangerous. Sneaker waves arrive without warning, far higher up the beach than the water line suggests. People have died there. Keep the sea in front of you at all times. Stay high on the beach, well back from the water line, and take photographs from a distance.
Come back to 360 Hotel. The pools feel different after a day like that.
Day three: do not get in the car
The still day, and the one most itineraries leave out.
Breakfast without an alarm. The spa in the morning is a different room from the spa in the evening. Cooler air, fewer people, the light coming up over the volcanoes. There is a wood beside 360 Hotel Boutique & Spa to walk in, which is a rarer thing in Iceland than it sounds. Urriðafoss is five minutes away and carries more water than any waterfall in the country, about 360 cubic meters a second.
Inside 360 Hotel Boutique & Spa there is Móri's Winter Garden, a cinema room, a billiard table and a library. Between October and March that is not a consolation prize.
In the evening, the 360 Hotel house car runs guests into Miðbær Selfoss, fifteen minutes away, subject to availability. The town's recreated old centre, where traditional Icelandic houses lost or demolished elsewhere have been rebuilt and now hold restaurants, cafés and small shops. Dinner there, then the car brings you back, and nobody drives in the dark.
Day four: the one three days cannot reach
Here is where the extra days earn themselves.
In summer: Þórsmörk. A glacial valley of birch woods between three ice caps, and there is nothing else like it in the south. You cannot drive there in a rental car — the route crosses unbridged rivers and needs the highland bus or a modified four-wheel drive. It is a full day, summer only, and standard rental insurance does not cover river crossings. Book the bus from Hvolsvöllur. On a three-day trip this is impossible. On a five-day trip it is the best day of the week.
In any season: Þjórsárdalur. Inland, and almost unvisited. Gjáin is a small green gorge full of little waterfalls that feels like a mistake in the landscape. Háifoss is among the tallest falls in the country. Access is gravel and varies by season, so check road.is on the morning you go rather than the week before. The road is why it is empty, and the emptiness is the reward.
Or bathing, properly. Reykjadalur is three kilometers uphill on foot to a river warm enough to lie in. Laugarás Lagoon is twenty minutes north above the Hvítá. An infinity pool, and the first cascading waterfall at any Icelandic lagoon. Reykjaböð opens at the mouth of the Reykjadalur valley in September 2026. The Secret Lagoon at Flúðir was built in 1891 and is the oldest pool in Iceland.
Day five: the spare one
Do not plan it.
That is the whole point. Weather will take half a day at some point in an Icelandic week, and a trip with no slack turns that into a loss. A trip with a spare day absorbs it and never notices.
If the weather holds and nothing needed rescuing, you have a free day in a country you now know slightly. That beats deciding it in advance from a spreadsheet at home. Go back to the thing you liked. Most people do.
What five days still does not buy
It does not buy the Ring Road. The east fjords, Mývatn and the north are a longer trip. Reaching them from the south in five days means two days in the car for one afternoon of payoff.
It does not buy the glacier lagoon at Jökulsárlón as a comfortable day trip either. It is possible from the south, and it is a long way, and people who attempt it on a short winter day regret the drive home.
Five days in the south is a complete trip on its own terms. It is not a compressed version of the whole country, and the trips that go wrong are the ones that try to make it one.
Choose fewer stops
The two extra days are not two more items on the list. They are the room to do the list properly, one day that reaches something three days cannot, and one day held back for whatever the weather decides.
Five days, one base, no packing in between.
360 Hotel Boutique & Spa opens on 3 October 2026, an hour from the Golden Circle and an hour from the south coast. Plan your stay.
Frequently asked questions
Is five days enough for South Iceland?
Comfortably, and it is enough to do the region properly rather than sample it. Five days covers the Golden Circle, a full south coast day, one longer trip such as Þórsmörk in summer or Þjórsárdalur inland, a still day, and a spare day for weather. It does not cover the Ring Road or the north, which need a longer trip.
Should I move hotels on a five-day trip in South Iceland?
Usually not. Both main routes are about an hour from a base near Selfoss, so moving costs you most of a morning each time and saves no driving. Checking out and checking in eats time that a single base simply gives back.
What can you do in five days that you cannot do in three?
Þórsmörk, which needs a full day and a highland bus and is summer only. Þjórsárdalur, inland and reached on gravel. A still day that is not a compromise. And a spare day for weather, which in Iceland is not a luxury but the difference between losing half a day and never noticing it.
Can you visit Jökulsárlón glacier lagoon from South Iceland?
It is possible and it is a long way. From near Selfoss it is a full day of driving with a short stop at the end, and in winter much of the return is in darkness. If the glacier lagoon is a priority, plan a night further east rather than attempting it as a day trip.
When is the best time for a five-day trip to South Iceland?
Late February for winter with usable daylight, roughly ten hours by the end of the month and the aurora season still open. Mid-September for the best overall balance, with about twelve hours of light and nights dark enough for the northern lights. June and July for the highlands, Þórsmörk and the midnight sun, accepting that the aurora is astronomically impossible in those months.
