The places that hold up are the ones where you walk twenty minutes
What Is Worth Your Time in South Iceland, and What Is Not
There is a pattern in South Iceland that takes most people a whole trip to notice. It is worth knowing on the first morning instead of the last.
The places that hold up are the ones where you walk for twenty minutes. The ones that disappoint are the ones you can see from the car.
That is nearly the whole rule, and the list below is what it produces when applied honestly to the places within about two hours of Selfoss.
Reykjadalur, the Þingvellir rift walk, Urriðafoss and Gljúfrabúi are worth the time without qualification. Gullfoss, Strokkur, Reynisfjara and Sólheimajökull are worth it with conditions attached. The Sólheimasandur plane wreck is not worth two hours of a short trip.
Worth it without reservation
Reykjadalur. The steam valley. About three kilometers (two miles) uphill on foot. You follow a river that gets warmer as you climb, until it is warm enough to lie in. Bring a towel and something to change behind, because there is very little shelter up there.
It appears on almost no itineraries, because it asks for effort. That is why it works. People remember what their legs did.
Reykjaböð, a new bathhouse and hot spring complex, opens at the mouth of the same valley in September 2026, with pools, a sauna and a restaurant reachable from the car park. The wild river is still up the hill where it always was. Two entirely different mornings, in one valley.
Þingvellir, but only the walk. The rift path runs between the North American and Eurasian plates. Forty minutes, minimum.
People who drive to the viewing platform, photograph it and leave have not been to Þingvellir. They have been to a car park above it. The geology and the history occupy the same ground here, and neither is visible from a windscreen.
Urriðafoss. Five minutes from 360 Hotel Boutique & Spa, on the Þjórsá river. It carries more water than any other waterfall in Iceland, about 360 cubic meters every second, which makes it the second highest by volume in Europe after the Rhine Falls.
It is four meters high. That is the whole point of it. Volume rather than height photographs badly and reads enormously in person, so it stays quiet while taller falls fill with coaches.
Being five minutes from 360 Hotel makes it easy to assume Urriðafoss is minor. It is not.
Gljúfrabúi. A few minutes north along the cliff from Seljalandsfoss, hidden inside a rock cleft you wade a short way into. Forty meters of waterfall in a chamber of its own, with daylight coming down the slot above it.
Almost nobody walks the extra distance, because the famous waterfall next door absorbs everyone who parks. Their loss. Waterproof footwear, and take care on wet rock.
Laugarás Lagoon sits above the Hvítá river, about twenty minutes north of Selfoss. An infinity pool over the water, a forest pool, a cold pool, a grotto, a sauna house facing the river, two swim-up bars and a restaurant. The cascading waterfall built into it is the first at any Icelandic lagoon.
It is a designed thing rather than a wild one, which is a different pleasure from Reykjadalur and no lesser for it. On a short winter day it is the easiest good decision available.
Miðbær Selfoss. The town's recreated old centre, where traditional Icelandic houses that were lost or demolished elsewhere in the country have been rebuilt and now hold restaurants, cafés and small shops. Fifteen minutes from 360 Hotel.
It is warm, it is characterful, and after a full day in open landscape it is exactly the right scale of place to end up in. Somewhere to walk around in the dark.
Worth it, with conditions
Gullfoss deserves twenty minutes and both levels. Most people see one.
Strokkur deserves twenty minutes and no more. It erupts every few minutes and catches you out even when you are watching for it. The rest of the Geysir field is small. There is not an afternoon in it.
Kerið is a twenty-minute stop on the drive north, and twenty minutes is the point of it. A volcanic caldera with a still lake at the bottom and an easy walk around the rim. Worth knowing while you stand there. Kerið is one of the craters of the Grímsnes volcanic field, and Grímsnes is one of the volcanoes visible from 360 Hotel. You have been looking at it all week.
Reynisfjara is visually extraordinary and it is genuinely dangerous. Sneaker waves arrive without warning, far higher up the beach than the water line suggests, and 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. Treat the warning signs as literal.
Sólheimajökull is the easiest place on the south coast to stand on a glacier, and standing on a glacier is worth doing. Go knowing what it looks like. It is gray and ash-streaked rather than the blue ice of the photographs, and it is retreating visibly year on year, which is its own reason to see it.
What to cut
The Sólheimasandur plane wreck. Four kilometers each way across flat black sand, to a photograph that already exists ten thousand times over. On a three-day trip those two hours buy you Gljúfrabúi and lunch. Spend them there instead.
The one most people never hear about
Þjórsárdalur, inland. 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 the road varies by season, so check road.is on the morning you go rather than the week before. That road is the reason the valley is empty, and the emptiness is the reward. For anyone who wants somewhere with no tour buses in it at all, this is the answer.
The honest caveat
Þórsmörk is better than everything on this list. 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, a full day, and summer. That is worth saying plainly now rather than letting anyone find out at the ford.
Book the bus. It runs from Hvolsvöllur and it is a good day out.
Why the rule works
Look back at the list. Reykjadalur is a walk. Þingvellir is a walk. Gljúfrabúi is a wade. The plane wreck is also a walk. It is the exception that explains the rule, because that walk crosses nothing and ends at nothing.
None of this is effort for its own sake. It is that the places you can see from the road have been seen from the road by everyone, and they behave accordingly. Twenty minutes on foot removes most of the crowd and all of the hurry, because the coaches run to a timetable that does not allow for anyone wandering off the tarmac.
The same logic applies to where you sleep. A trip that moves every night is a trip seen from the car. 360 Hotel Boutique & Spa sits on a hilltop between the two routes rather than at the end of either one, which turns the driving into two day trips instead of a chain of one-night stays.
Choose fewer stops. Walk the last twenty minutes.
Choose fewer stops
Pick two of these for a short trip. Give each one the morning it deserves. You will come home having seen less of the map and considerably more of the country.
360 Hotel Boutique & Spa opens on 3 October 2026, on a hilltop near Selfoss. An hour from the Golden Circle, an hour from the south coast, five minutes from Urriðafoss.

Frequently asked questions
What is the best thing to do near Selfoss?
Reykjadalur, the steam valley, is the strongest option within an hour. It is about three kilometers uphill on foot to a river warm enough to bathe in. Closer still, Urriðafoss is five minutes from 360 Hotel Boutique & Spa and carries more water than any waterfall in Iceland, about 360 cubic meters a second. It stays uncrowded because volume photographs less dramatically than height.
Is the Sólheimasandur plane wreck worth visiting?
For most short trips, no. It is a four-kilometer walk each way across flat black sand, with nothing to see along the route. The photograph at the end is one of the most reproduced images in Iceland. On a three or four day trip, those two hours are better spent almost anywhere else on the south coast.
Is Reynisfjara beach safe?
Reynisfjara is dangerous and has caused deaths. Sneaker waves arrive without warning and reach far higher up the beach than the water line suggests. Visit, and 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.
Can you drive to Þórsmörk in a rental car?
No. The route into Þórsmörk crosses unbridged rivers and requires a highland bus or a modified four-wheel drive vehicle. It is a full-day trip and is only possible in summer. Standard rental car insurance does not cover river crossings.
Where should I stay to see all of this?
Somewhere between the two routes rather than on one of them. The Golden Circle runs north of Selfoss and the south coast runs east, and each is about an hour away, which is what makes one base practical on a short trip. 360 Hotel Boutique & Spa opens on 3 October 2026 on a hilltop near Selfoss, five minutes from Urriðafoss and fifteen minutes from Miðbær Selfoss, with the spa included in the room rate.
What is better than Seljalandsfoss?
Gljúfrabúi, a few minutes north along the cliff. It sits inside a rock cleft that you wade a short distance into. Seljalandsfoss absorbs nearly everyone who parks there, so Gljúfrabúi stays quiet. Wear waterproof footwear and take care on wet rock.
