What Is the Secret Lagoon?

Secret Lagoon Experience

Secret Lagoon, as a part of the Golden Circle in Iceland, offers an outdoor geothermal pool where visitors rest in warm mineral water in an open-air setting surrounded by the rural countryside. The lagoon has a natural layout shaped by the land and by Iceland’s geothermal activity.

Steam rises from the warm water, especially in cooler air, and nearby geothermal vents and small bubbling areas reveal natural heat beneath the surface. The pool is located in open countryside with low vegetation, exposing visitors to wind, rain, or cold air while they remain immersed in warm water.

Water Temperature and Steam Conditions?

Secret Lagoon maintains an average water temperature of 38–40 °C (100–104 °F), though it may vary slightly depending on natural geothermal flow and weather conditions.

Steam is visible when the hot geothermal water meets cooler outdoor air. When air temperatures drop, especially in winter, the contrast increases and more steam forms above the pool surface.

How Deep Is the Secret Lagoon Pool?

The Secret Lagoon has a depth of approximately 0.8-1.6 meters (2.6–5.2 feet). The deepest parts reach about 1.6 meters (5.2 feet), while shallow areas remain around 0.8–1.0 meters (2.6–3.3 feet).

Depth varies across the pool; shallow areas are near the edges and entry points, while deeper areas are closer to the center.

Most adults can stand comfortably in many parts of the pool, though non-swimmers should remain cautious in deeper areas.

Does the Water Contain Chlorine?

Yes, the Secret Lagoon uses chlorine as part of its water treatment system.

Although the pool is filled with naturally heated geothermal water, chlorine is added to maintain hygiene and safe bathing conditions for visitors.

Water treatment is required under Icelandic public health regulations, which apply to all public bathing facilities and require regular monitoring to prevent bacterial growth.

The geothermal water at the Secret Lagoon continuously circulates and is refreshed by nearby hot springs, while chlorine helps maintain consistent sanitation standards.

Rules and Safety at Secret Lagoon

Secret Lagoon requires visitors to follow basic safety rules and bathing regulations to maintain hygiene and safe use of the facility.

All guests must shower before entering the pool. The shower requirement supports the lagoon’s hygiene standards. Visitors must wash without swimwear before putting on swimwear and entering the water.

Children require constant supervision. Parents or responsible adults must provide supervision for children in the pool and surrounding bathing areas.

The facility follows and complies with Iceland’s public health standards for public bathing facilities.

Is the Secret Lagoon Accessible in Winter?
