Overview
A historic geothermal pool that keeps things simple
Secret Lagoon (Gamla Laugin) is often described as Iceland’s oldest swimming pool, built in 1891 in a geothermal area near Flúðir. The experience is closer to a traditional local pool than a glossy “lagoon spa.” You soak in one main outdoor basin, with steam rising from nearby vents and small hot springs visible along a short walking path.
What to expect on a real visit
Facilities are straightforward: changing rooms, showers, lockers, and a counter for entry and rentals. There is no big multi-zone complex to navigate, which makes it an easy stop if you want warm water without turning the day into an event. When it’s busy, it feels social and shared. When it’s quiet, it feels wonderfully old-fashioned.
Why people pick it
It sits naturally on a Golden Circle day and works well in any weather. If you want something more classic and less staged than the major lagoons, this is often the comfortable middle ground.
Location & Access
Where it is
Secret Lagoon is at Hvammsvegur, 845 Flúðir, in South Iceland. The operator publishes coordinates and clear directions for navigation.
Getting there
This is drive-up access on paved roads, no hike. Most visitors arrive by car as part of a Golden Circle loop. In winter, plan extra time for wind, ice, and reduced visibility. The final approach is easy, but it still pays to drive like conditions can change quickly.
Parking and arrival
On busy days, arriving earlier helps. Pre-booking is strongly encouraged by the operator because entry can sell out. If you show up without a reservation in peak season, have a backup plan nearby.
What to bring
Swimsuit, towel, and non-slip sandals make the visit easier. Add a warm hat and dry layer for the walk between water and changing rooms. A small waterproof pouch for your phone keeps you from juggling wet hands and cold air.
Before you go
Check the official site for current opening times, booking status, and any operational notes. It’s a simple place, but it’s popular enough that planning matters.
Suitability & Accessibility
Secret Lagoon is best for travelers who want a classic geothermal soak with minimal logistics. It works well for first-time Iceland visitors, couples, solo travelers, and families who prefer a straightforward pool over a sprawling spa.
Families
Family friendly, with supervision expectations. The operator states that children 16 and under must be accompanied by an adult (and limits how many children one adult may accompany). Keep kids to shorter soak rounds and avoid long, overheated sessions.
Mobility realities
No hiking, but expect wet surfaces, steps typical of pool edges, and short outdoor transitions. The simplest approach is to move slowly, keep sandals on outside the water, and use handrails when available.
Wheelchair expectations
I’m not claiming step-free routes or water-entry aids without a clear, current accessibility statement from the operator. If step-free access is essential, contact Secret Lagoon before you commit and ask about thresholds, changing-room layout, and pool entry options.
Expectations vs reality
This is not a luxury lagoon. The charm is that it feels real and a little old-school. If you want multiple pools, swim-up bars, or long indoor lounges, you’ll be happier elsewhere.
Safety & Etiquette
Heat pacing keeps the day comfortable
Warm water can feel gentle while it quietly tires you out. Do shorter rounds, take breaks, and drink water. If you feel lightheaded or unusually tired, step out and cool down.
Slips are the most common real problem
Wet concrete, wet tile, and steps are where people get hurt. Non-slip sandals help more than almost anything. Walk slowly, especially when you’re warm and relaxed.
Geothermal edges are not play zones
There are small hot springs and steam vents around the pool area. Stay on marked paths and keep children close. It goes best when everyone treats the steaming ground with a little respect and a little distance.
Hygiene and showers
Showering before entry is part of normal Icelandic pool culture. A quick, thorough rinse helps keep shared water pleasant.
Shared-space etiquette
Don’t block entry steps, give others room at the edges, and keep voices lower if the pool is calm. Photos are easier on everyone when you keep other guests out of frame.
Kind cautions
If you’re pregnant, heat-sensitive, or managing cardiovascular concerns, keep sessions conservative and skip dramatic hot-to-cold swings. A gentler pace usually feels better.

Swimsuit, towel, and non-slip sandals. Add a warm layer for the walk back to the changing rooms and a waterproof pouch for your phone.
Is Secret Lagoon a natural hot spring?
It’s a historic swimming pool fed by geothermal water, in a geothermal area with vents and hot springs nearby. You soak in a managed basin with facilities.
Is it wheelchair accessible?
Don’t assume. Contact the operator for current details on step-free routes, changing areas, and the easiest pool entry before you plan your visit.
