Origins of Secret Lagoon

Secret Lagoon, known locally as Gamla Laugin (the old pool), began as a simple village bathing place in the late 19th century. In a valley of farms and greenhouses warmed by geothermal energy, people gathered to wash, to warm up after winter chores, and to share news in the quiet steam.

Through the decades, the pool drifted in and out of use, shaped by weather and rural life. When modern renovations welcomed visitors again, they kept the spirit of the original: a modest pool, clean facilities, and the soft companionship of warm water and cool air — the Icelandic way.

Geothermal heart of Flúðir

Beneath Flúðir, hot water moves through ancient rock, carrying minerals and steady heat to the surface. The same energy that warms greenhouses and kitchens fills the lagoon, creating a naturally heated pool that feels like an embrace from the earth itself ♨️.

Around the lagoon, small vents breathe and hiss; the ground glows with frost in winter and grasses sway in summer. This is everyday geothermal Iceland — not a theme park, but a landscape that quietly works for people.

Icelandic bathing traditions

In Iceland, bathing is both practical and joyful. Hot water has long meant comfort after chores, a social pause in the week, and a moment where everyone, farmer or traveler, can rest bones and talk softly in the steam.

Secret Lagoon continues that tradition with no flash — just warm, mineral water, thorough showers, and shared calm. The etiquette is simple: be kind, be quiet, and let the heat do its gentle work.

Facilities: simple and sincere

You’ll find clean changing rooms, showers, towel rental, and a small café. No towering slides or loud music — just the essential comforts that make warm water even better.

The pool itself is modest in size, edged by rough stones and wooden walkways. Steam rises, the air stays cool, and the rhythm slows — a fine match for the countryside.

Countryside life & seasons

Spring brings bright grass and quick weather shifts; summer stretches into long evenings; autumn folds into mist and gold; winter arrives with crisp air, snow, and that satisfying contrast of icy cheeks and warm shoulders.

Farm greenhouses glow nearby, powered by hot water from the earth. In every season, the lagoon feels like a small, steady kindness.

Litli Geysir and hot springs

A short path loops around the geothermal field where Litli Geysir bubbles and breathes. It’s small but lively — a reminder that the water warming your shoulders comes from deep within the earth 🌋.

Please stay on marked paths and mind the edges — the ground can be fragile and very hot. Steam looks friendly; rocks do the real work.

Routes, roads & day trips

Most visitors pair Secret Lagoon with classic Golden Circle stops like Thingvellir, Geysir, and Gullfoss. Driving is straightforward, with paved roads and clear signs — but always check weather in winter.

Guided tours handle logistics and timing, especially useful in snow season. Self‑drivers enjoy flexibility and can linger in the water a little longer 😊.

Safety & accessibility

Steaming geothermal ground

Showers are required for hygiene; move slowly on wet surfaces; keep glass bottles out of the pool. In winter, walkways can be icy — use handrails and wear sturdy footwear.

Facilities are improving and staff can assist. If mobility is limited, contact the lagoon ahead of time to confirm current accessibility and best entry times.

Local events and rural rhythm

Check local listings for special evenings or extended hours. Slow travel suits this place; let the day unspool at a rural pace.

Why this lagoon matters
