Your Guide to Secret Lagoon

Hidden in the peaceful village of Flúðir, the Secret Lagoon is one of Iceland’s most beloved spots for relaxation and exploration. Known for its historical significance and natural beauty, this geothermal pool offers the perfect way to unwind while immersing yourself in Iceland’s incredible landscapes and unique culture.

A Bit of History

When you visit the Secret Lagoon, you’re stepping into a location with over a century of history. Dating back to 1891, the Secret Lagoon holds the title of being Iceland's oldest natural pool. At a time when geothermal energy was still a developing concept, locals recognized the natural hot springs in Flúðir as a place of comfort and healing. It quickly became a social and recreational hub for the community.

The pool itself has evolved over time. While it has been modernized to accommodate visitors, it retains its rustic charm with natural stone walls and original features, such as the small geysers that erupt regularly nearby. The lagoon’s preservation allows visitors to experience Iceland’s geothermal culture as it was over 130 years ago, making it a living museum as much as a relaxing retreat.

Natural Thermal Bliss

The Secret Lagoon isn’t just any thermal pool—it’s an invitation to experience Iceland’s powerful geothermal forces firsthand. Fed by underground hot springs, the lagoon maintains a consistent temperature of 38-40°C (100-104°F). The water is rich in minerals that are said to have therapeutic properties, soothing tired muscles and leaving your skin feeling refreshed.

Unlike many commercialized spas, the Secret Lagoon prides itself on its natural simplicity. You won’t find artificial jets or chlorinated water here—just pure geothermal energy straight from the earth.

For an extra touch of magic, keep an eye out for the bubbling geysers located just a few steps from the pool. These mini eruptions occur every few minutes, a gentle reminder of the volcanic activity that defines Iceland.

Surrounded by Serenity

The Secret Lagoon is surrounded by a picture-perfect landscape that changes with the seasons. In summer, the rolling fields are lush and green, dotted with colourful wildflowers. In winter, a blanket of snow transforms the area into a serene wonderland, with steam rising dramatically from the warm water.

For many visitors, the highlight is the chance to see the Northern Lights. On clear winter nights, the auroras often appear, casting vibrant colours across the sky. Imagine soaking in warm waters with the night sky dancing above you—it’s an experience you’ll never forget.

Even without the Northern Lights, the setting is deeply calming. You’ll hear the gentle hum of the geysers, the rustling of nearby grasses, and the occasional chirp of birds. It’s a sensory escape that feels worlds away from the busyness of daily life.

More than Just a Lagoon

While the Secret Lagoon is the main draw, the surrounding area offers plenty to explore. Just a short walk away are trails that meander through fields of bubbling hot springs and steaming earth. It’s a great way to connect with Iceland’s raw, untamed nature.

If you’re feeling adventurous, you’re in luck—Flúðir is close to some of Iceland’s most iconic attractions. The Golden Circle, which includes the Geysir Geothermal Area, Gullfoss Waterfall, and Þingvellir National Park, is just a short drive away. After a day of sightseeing, returning to the warm waters of the Secret Lagoon is the perfect way to unwind.

Local dining options in Flúðir also offer a taste of Icelandic cuisine. Try some freshly baked rye bread, cooked underground using geothermal heat, or enjoy locally sourced lamb and vegetables at nearby restaurants.

Plan Your Visit

The Secret Lagoon is open year-round, so you can enjoy its magic no matter when you visit Iceland. Hours vary depending on the season, with extended evening hours in winter to maximize your chances of seeing the Northern Lights. Be sure to check the official website for the latest information on opening times and ticket prices.

For a more relaxed experience, try to visit early in the morning or later in the evening, when the lagoon is quieter. Remember to bring a swimsuit and a towel—rentals are available on-site, but many visitors prefer to bring their own.
