The 5 Best Hot Springs in South Iceland

1. Reykjadalur Hot Spring

Reykjadalur is a hot spring river just outside Hveragerði. To get there, you’ll take a 3-kilometer hike through a beautiful valley with steaming vents and bubbling mud pools along the way. When you reach the river, you can find a quiet spot, hop in, and enjoy the warm water surrounded by nature.

It’s completely free, which is a bonus. Once you’re done soaking, you can stop in Hveragerði for a coffee or snack. It’s a great mix of a little adventure and some downtime.

2. Seljavallalaug

Built in 1923, Seljavallalaug is one of Iceland’s oldest pools. It’s tucked into a valley near Seljavellir and surrounded by mountains. The pool is filled with warm spring water, and while the facilities are basic—don’t expect fancy changing rooms—it’s a quiet and relaxing spot.

There’s no entry fee, and it’s close to some of Iceland’s top attractions, like Seljalandsfoss and Skógafoss. If you’re looking for a simple, peaceful place to unwind after exploring, this is a good choice.

3. Hrunalaug Hot Spring

Hrunalaug is a small hot spring near Flúdir that feels private and peaceful. The main pool is made of stones, with a little turf-roofed shelter nearby. It’s cozy, quiet, and perfect if you’re looking to avoid crowds and just relax.

There’s a small fee—2,500 ISK ($18) for adults, with discounts for kids—since it’s on private land. While you’re nearby, you can also visit the Secret Lagoon or grab some food at Restaurant Mika in Flúdir, which is known for its langoustine. Hrunalaug is great if you’re after something calm and laid-back.

4. Secret Lagoon

The Secret Lagoon, also called Gamla Laugin, is Iceland’s oldest swimming pool, built in 1891. The pool is naturally warm all year, and there’s even a small geyser nearby that erupts every few minutes.

Admission is 3,600 ISK ($27) for adults, and kids under 14 can enter for free with an adult. It’s got proper changing rooms and a small café, so it’s a good option for families. It’s also close to Gullfoss, Geysir, and other Golden Circle stops, making it easy to add to your plans.

5. Landmannalaugar Hot Springs

Landmannalaugar is in the Icelandic Highlands and is surrounded by colorful mountains and lava fields. Both hot and cold streams feed the hot springs, so you can find the perfect spot to soak.

Getting here takes some planning—you’ll need a 4x4 to handle the rough roads, and it’s only accessible in the summer. But it’s worth the effort, especially if you enjoy hiking, as the famous Laugavegur trail starts here. The combination of the scenery and the natural pool makes it a special spot to visit.

Conclusion

If you’re planning a trip to South Iceland, these hot springs are definitely worth a visit. From the relaxing river at Reykjadalur to the scenic Highlands at Landmannalaugar, each one offers its own unique experience. They’re great places to take a break and enjoy Iceland’s amazing landscapes.
