Iceland’s Hidden Hot Springs: A Self-Drive Guide to Secret Soaks

There’s a certain magic to soaking in a natural Icelandic hot spring, surrounded by sweeping landscapes, distant glaciers, or rolling green hills. While the Blue Lagoon and Sky Lagoon are world-famous, Iceland is home to hundreds of lesser-known geothermal gems—quiet retreats where you can relax in peace, often with no one else around.

This guide is for the adventurer-at-heart. If you're ready to go beyond the typical tourist route, hiring a car in Iceland gives you the freedom to uncover these secluded soaks at your own pace. Whether you’re planning a weeklong Ring Road itinerary or a spontaneous weekend from Reykjavík, Höldur’s self-drive car rentals help you unlock the country’s hidden treasures.

Let’s explore the top secret hot springs you can reach by car—each one offering a warm welcome far from the crowds.

Why Go Off the Beaten Path?

While famous lagoons have their appeal, the true soul of Iceland lies in its untouched landscapes and local secrets. Hidden hot springs not only provide solitude, but often lie amid some of the most breathtaking backdrops Iceland has to offer—from moss-covered lava fields to remote highland valleys.

Self-driving is the key to reaching these spots. Public transport rarely services remote areas, and many hot springs aren’t marked on maps. With your own vehicle, you’re not tied to timetables or crowded buses. You choose the route, the pace, and the places that resonate with your sense of adventure.

7 Hidden Hot Springs to Discover by Car

 

1. Reykjadalur Steam Valley – Hveragerði

Just a 45-minute drive from Reykjavík, this geothermal river runs through a scenic valley where hot springs bubble from the ground. A moderate hike (about 3 km) from the parking area brings you to natural pools perfect for soaking.

Tip: Arrive early to avoid the small crowds that gather mid-morning.

 

2. Hrunalaug – Near Flúðir

A local favourite, Hrunalaug is a tiny, rustic hot spring tucked behind a farm. The surrounding hills and traditional stone structures add to its storybook charm.

Access note: The spring is on private land, but the owners allow respectful visitors. Leave no trace.

 

3. Seljavallalaug Pool – South Coast

Nestled in a narrow valley near the Eyjafjallajökull volcano, this old stone pool is fed by a hot spring and surrounded by dramatic mountains. Park your car and take a 15-minute hike in.

Best for: Photographers and those seeking a unique blend of history and nature.

 

4. Hellulaug – Westfjords

Overlooking the sea, Hellulaug offers one of the most remote and scenic soaks in Iceland. The water temperature hovers around 38°C, and it’s free to the public.

Self-drive benefit: This one is truly off-the-grid—your own wheels are essential.

 

5. Grettislaug – North Iceland

Named after a legendary Icelandic outlaw, this pool by the sea near Sauðárkrókur offers epic fjord views. There's a small entrance fee, and simple changing facilities on site.

Nearby: Stay overnight at the nearby guesthouse to enjoy a moonlit soak.

 

6. Laugar í Sælingsdal – West Iceland

A true hidden gem in the Dalabyggð region, Laugar í Sælingsdal is a historic geothermal spot with deep cultural roots. Once a bathing place of medieval chieftains, today it features a warm outdoor pool surrounded by hills, fields, and silence.

Perfect for: Travellers tracing history or craving rural tranquillity. Easily accessible by car, it makes a peaceful detour on a West Iceland road trip.

 

7. Laugafell – Icelandic Highlands

Remote and utterly wild, Laugafell sits in the heart of the highlands, surrounded by vast plateaus and silence. The geothermal pool is fed by natural hot springs, with basic hut accommodations nearby. It’s open during the summer months and accessible only by 4x4.

Driving tip: Check highland road conditions on road.is before attempting. The adventure is worth the journey.
