When you hear about Iceland, the first thing that probably comes to your mind is dramatic landscapes, waterfalls, and campervans, but did you know that it’s also home to Reykjadalur thermal river? which should be high on your Iceland list. Yeah, despite Iceland having a high volcanic history and landscape, somehow this hidden gem has gone unnoticed by tourists.
Reykjadalur, Iceland, is one of those places that sounds like fake news when people describe it: steam rising from hills, the ground with that sulfur smell, and the clearest river you will see running through the valley… a warm, almost hot to the touch river.
I mean, a geothermal river that Iceland locals have known for ages and is now open for travelers? You must check it out and this guide will walk you through everything you need to know before you go.
Why Is the Reykjadalur Valley Famous?
One of the first things you need to know is that Reykjadalur actually means “Steam Valley,” and the name fits perfectly. You will notice it as soon as you get there: the whole valley is packed with steaming vents, bubbling mud pools, and some slopes are brushed with mineral colors; it’s almost otherworldly.
But what really made this whole valley popular is the thermal river in Iceland, and yes, you can actually bathe there.
The second most important thing you need to know before going is that, unlike most Icelandic hot springs, which are pools or even tubs, this is a full-natural flowing river. Amazing, right? I know what you must be thinking: Is it not too hot for people? And the answer is no, the hot water coming from the underground gets mixed with cold mountain water (the runoff), and this creates a stretch where the temperature is just right for taking a dip.
Walk a little upstream, and it gets hotter. Walk down, and it cools off. You choose! The best part is that this mix of wild scenery and simple access is what sets Reykjadalur apart.
Where Is Reykjadalur in Iceland?
Reykjadalur is located in southwest Iceland. It’s situated near the small town of Hveragerði and sits about 45 minutes east of Reykjavík by car, making it one of the easiest geothermal rivers in Iceland to reach on a short trip.
It has a privileged location, the valley is just inland from the Rin Road area, and is surrounded by green hills in summer and a snowy slope during the colder months.
The valley lies just inland from the Ring Road area, surrounded by green hills in summer and snow-dusted slopes in colder months. Because of its location, many people visit Reykjadalur, Iceland, as a day trip from Reykjavík or as a stop on a Golden Circle-style route.
How to Get to Reykjadalur Hot Spring River
Getting to the Reykjadalur hot spring river is part of the adventure, and it is even better if you have a Reykjavik Cars, especially if you’re staying in Reykjavík. From there, all you need to do is drive east on Route 1 toward Hveragerði. Just before or after town, signs point you toward Reykjadalur parking.
The parking area is free and fairly large, though it can fill up during busy summer days. Now, for campervans, we believe the best option is Campervan Iceland, and the closest campsite to the park is Reykjamörk Hveragerði Campsite.
From the parking lot, the hike begins right away. There is no shuttle and no road access beyond this point, which helps keep the valley feeling natural.
If you don’t have a car, some tours include Reykjadalur as a stop, but hiking on your own gives you more freedom to stay as long as you like.
What the Hike to the Hot River Iceland Is Like
I know that many people are not that fond of hiking, but chances are that you love this one (especially if you travel to a highly natural country). The hike to the thermal river in Iceland is part of the experience. It takes about 45 to 60 minutes each way, depending on pace and weather.
The trail is clearly marked and well-worn, but it is usually categorized as a medium or challenging because it’s uphill most of the way, and that can be hard.
As you walk, you can expect rolling terrain, some paths filled with gravel, and some even steeper sections. You will pass through steaming vents, small waterfalls, and stunning wide views over the valley.
On clear days, the landscape feels open and calm. On foggy days, it can feel mysterious and quiet, almost mystical. The trail can be muddy after rain or snowy in winter.
You don’t need hiking boots, but sturdy shoes with grip help a lot. Even though the hike isn’t extreme, it’s not a flat walk either, so plan accordingly.
Bathing in the Hot River
Once you reach the river, you’ll see wooden boardwalks and simple partitions where people change. This is not a private setup. Everyone shares the space, and change happens in the open. Most people use towels to wrap around themselves while switching clothes.
The river itself stretches along the valley floor. If it’s your first time, test the water with a hand or foot before settling in.
Also, keep in mind that the bottom of the river is rocky and uneven, so move slowly when entering. Once you find your spot, sitting back and letting the warm current flow around you feels incredible.
Rules, Restrictions, and Safety
Bathing in the Reykjadalur thermal river is allowed only in the designated river area. The surrounding hot springs and vents are dangerous and off-limits. Some pools look tempting, but the water can be boiling just below the surface.
Stay on marked paths at all times. The ground can be thin and unstable in geothermal areas. Signs are posted for a reason, and following them keeps everyone safe.
There are no lifeguards. You enter the water at your own risk, so be mindful of slippery rocks and changing temperatures.
Visiting Reykjadalur Valley
The Reykjadalur thermal river is one of those places that feels both simple and unforgettable. A hike, a river, warm water from deep underground, nothing fancy, yet deeply satisfying. If you want to experience the geothermal river Iceland is famous for, this is a perfect first stop.
Go prepared, respect the land, and give yourself time to enjoy it. The reward is a peaceful swim surrounded by steam, hills, and the quiet power of nature doing its thing.
