Flúðir

Flúðir is a small, quietly extraordinary village in South Iceland where geothermal energy shapes almost every aspect of daily life. Sitting just south of the main Golden Circle route, it rewards visitors who venture a short detour with warm pools, greenhouse farms, and a genuine taste of rural Icelandic life without the crowds of the major tourist stops.

The Secret Lagoon (Gamla Laugin)

The village's best-known attraction is the Secret Lagoon — Iceland's oldest swimming pool, first built in 1891. Fed by natural hot springs, the water hovers at a comfortable 38–40°C year-round, making it a relaxing soak in any season. A short boardwalk around the pool passes steaming vents and Litli Geysir, a small but lively geyser that erupts regularly. Unlike larger, more commercialised geothermal baths, the Secret Lagoon has a wonderfully unpretentious feel — steam rises over open countryside rather than over a resort complex.

Geothermal Greenhouses and Farms

Flúðir's other claim to fame is its concentration of geothermal-powered agriculture. The heat that warms homes and pools also heats large greenhouses that produce tomatoes, cucumbers, and other vegetables throughout Iceland's long winters.

• Friðheimar is the most visited of these farms — a working tomato greenhouse with an on-site restaurant where you eat surrounded by rows of ripening plants; the menu leans heavily, and deliciously, on what grows just a few feet away.
• Flúðasveppir is Iceland's only dedicated mushroom farm, producing white, chestnut, and portobello varieties; the on-site bistro serves dishes made from the day's harvest.

What Else to Do Around Flúðir

The area around the village offers more than just hot pools and farm dining:

• Horse riding tours through the South Iceland countryside
• Hiking on nearby Miðfell mountain for views across the farmland
• Exploring the basalt column gorge at Brúarhlöð, a short drive away
• A local community pool and golf course if you have extra time

Fitting Flúðir into a Golden Circle Day Trip

Flúðir lies roughly 25–30 minutes from both Geysir and Gullfoss, making it a natural lunch or late-afternoon stop as you loop back toward Reykjavík. A Golden Circle itinerary that swings through Þingvellir, Geysir, and Gullfoss in the morning can comfortably include a soak at the Secret Lagoon and lunch at Friðheimar without feeling rushed. Because it sits slightly off the main tourist corridor, Flúðir tends to be noticeably quieter than the headline stops — a genuine plus in the summer peak season.
