"Reykjadalur means "Steam Valley"—a perfectly apt description of this pleasant geothermal area close to the town of Hveragerði, a 40-minute drive south from Reykjavík . Formed from a now extinct volcano (Mount Hengill), the valley is best experienced via a two-mile walk along a gravel road, which leads into the hot springs. The hour-long stroll—fairly easy but quite narrow in places—is highly photogenic thanks to the presence of boreholes, waterfalls, and springs, so bring your camera as well as your swimming gear. Be sure also to use only the official bathing pools, since although the light-blue water may look innocent, some pools are hot enough to cause severe burns. If you don't have a car to get to the site, you can visit the springs via an official tour, which can be donein combination with some horse riding. There is also a restaurant close to the parking lots and bathrooms."

The hike was beautiful. I didn't really care for the gravel on the trails but the views were absolutely incredible. When you get up to the hot springs river it's cooler farther down the river. The springs are pretty hot up top. I did find one spot where this cool Creek was coming into the hot part and there was a nice little warm pool , just the right temperature after the hike to get up there. The water is really hot so be prepared for that. Probably best in the winter. They have little t-shaped changing spots but you will be exposed. If you walk farther up past where everyone is a little more comfortable to change in or out of your swimsuit. Overall it was an amazing experience. The water was just too hot and I slipped on the gravel a couple times coming down.

I did a hiking route in the area of about 12 kilometers in which geysers are seen along almost the entire route. The route is beautiful. The thermal river has a wooden platform that makes it easier to access and then change. This area adapted for bathing is very crowded.

Long 4km hike each way but so very worth it! Nestled way back in the hills is this fantastic natural hot spring for soaking. There are basic 2sided walls up for changing. Temperature was variable based on distance from the headwaters. It was perfect. No fee other than standard parking lots both fee at bottom of first hill

Great experience! We did the hike with our toddler and really enjoyed it. It took us about 1 hour and 30 minutes to get there and 1 hour to return. The first 10 minutes were uphill and a bit challenging, but after that the trail was much easier. The hot spring at the end was very hot and totally worth it!

Nice little hike to geothermic river spring, not very hard. Water is warm, if you go higher upstream is getting hotter. Pretty shallow. Usually a lot of people if it's good weather or weekend.

Okay, this hike was LONG! We went with our two kids (6 and 8) and it took us 1.5+ hours to get there and about 1 hour to get back. Every time we were sure the river would be just around the corner, it wasn't XD I would also say that this hike is MOSTLY uphill. We went in the evening (started our hike at 6:45pm) and there were not many people by the time we arrived (8:30). Even when we made it back to our car around 10:15, there were a handful of people just heading out on the hike! The surrounding area is BEAUTIFUL. I got some of my favorite pictures from our trip here. The water was so nice and warm. The wind was STRONG! Truly a one of a kind experience :)

The parking is via EasyPark, it's paid by hour. We paid about 1000ISK for 4 hours. It's about 3km hike, and it took us 45-50 min to go up, it was a hot day and the hike was not that easy. The nature is amazing though. Hot springs are very hot, I mean very! It's almost unbearable to step inside this hot water. Should be much more pleasant during winter time. There are no changing cabins nearby.

Amazing thermal river hot spring! It’s about 2.5 miles of hiking to get to the part where you can soak. The first mile or so is straight uphill, but after that it’s a more manageable, rolling incline. The way up took us about 1-1.5 hours. Gorgeous views on the way up. We loved seeing the steam billowing from the mountains, streams, and small pools. The pools are really nice and warm. They get hotter as you go up, but even the lowest pool is nice. Mostly shallow, but there are some deep pockets where you can submerge up to your neck while sitting. Water is a bit dirty and mossy, but it’s a natural river so that’s expected. There are stairs to get in the water, but bring water shoes because the riverbed is rocky. Changing dividers offered a bit of privacy but not much.
