Unveiling Iceland's Hidden Gem: The Secret Lagoon

Planning a trip to Iceland and looking for a chill spot to relax? You should check out the Secret Lagoon in Flúðir. Imagine soaking in warm hot springs while little geysers bubble nearby and steam rises around you—it's pretty awesome. Located in a small village, this place lets you unwind and get close to nature and Iceland's geothermal power.

Key Takeaways

  • Location: The Secret Lagoon (Gamla Laugin) is in Flúðir, South Iceland, about 1.5 hours (105 km) from Reykjavik.
  • Unique Feature: It's Iceland's oldest natural hot spring pool, with active geysers that spout every few minutes.
  • Facilities: A big natural hot spring pool, paths around the geothermal area, modern changing rooms, showers, and a cozy café.
  • Temperature: The lagoon stays at a comfy 38-40°C (100-104°F) all year.
  • Atmosphere: Offers a peaceful and real Icelandic experience, less crowded than other popular spas.

History and Formation

Locals call it Gamla Laugin, and it's been around since 1891, making it the oldest swimming pool in Iceland. It used to be where villagers bathed and hung out. They built a pool using natural hot spring water—so it's like a natural hot tub. For years, it was a community spot, even used for swimming lessons when that became part of school.

Over time, as new places opened, the lagoon was left unused around the 1940s. But in 2014, someone decided to bring it back. They kept its old-school vibe but added some modern stuff to make it comfy for visitors now. Now, it's open again, offering a mix of history, nature, and a place to chill.
