The Secret Lagoon: Iceland’s Hidden Gem of Relaxation and Discovery

Tucked away in the small village of Flúðir, the Secret Lagoon (Gamla Laugin) is one of Iceland’s best-kept treasures — a serene geothermal pool surrounded by steam, moss, and pure tranquillity. Unlike the larger and more commercial Blue Lagoon, the Secret Lagoon offers a truly authentic Icelandic hot spring experience, where you can soak beneath open skies while the surrounding geothermal landscape bubbles and breathes around you.

For travellers planning a self-drive trip through Iceland’s Golden Circle, the Secret Lagoon is a perfect stop — blending natural beauty, local heritage, and easy access via a scenic drive from Reykjavík. With Höldur’s reliable car hire services, you can enjoy this unique spa-like retreat at your own pace, turning your road trip into a journey of discovery.

Why the Secret Lagoon is So Special

The Secret Lagoon is the oldest man-made swimming pool in Iceland, built in 1891. Its warm, mineral-rich waters are fed directly from nearby hot springs, maintaining a constant temperature of around 38–40°C year-round.

The atmosphere here is truly magical — rising mist drifts across the water, birds call in the distance, and the gentle sound of bubbling geothermal vents reminds you of Iceland’s living earth beneath your feet.

This is not just another tourist stop; it’s a living part of Iceland’s culture. Locals have been bathing here for over a century, long before Iceland became the world’s ultimate travel hotspot.

The Experience: What to Expect

Upon arrival, you’ll notice the lagoon’s natural charm. The pool is surrounded by lava rock, steam vents, and small bubbling geysers that erupt every few minutes. Wooden walkways circle the area, allowing visitors to explore safely and take in the landscape.

Facilities are modern yet simple — changing rooms, showers, and a small café offering hot drinks and light snacks. Bring your own swimsuit and towel (or rent them on site).

The water’s steady warmth makes it comfortable to soak for as long as you like. Many travellers spend about an hour to 90 minutes here, letting the geothermal minerals ease away the tension of travel.

Pro tip: Visit early in the morning or late afternoon for the most peaceful atmosphere.

Nearby Attractions: Complete Your Golden Circle Drive

The Secret Lagoon fits perfectly into a Golden Circle self-drive itinerary, alongside Iceland’s most iconic natural wonders.

Þingvellir National Park

A UNESCO World Heritage Site and one of Iceland’s most historic landmarks. Walk between the tectonic plates of North America and Eurasia, and witness the birthplace of Iceland’s democracy.

Geysir Geothermal Area

Only a short drive from Flúðir, this active field of geysers and hot springs is where the word “geyser” originated. Watch Strokkur erupt every few minutes, shooting boiling water high into the air.
