We set off from Reykjavík and headed south towards Flúðir, where Secret Lagoon — or Gamla Laugin — is located.
But Secret Lagoon isn't just another geothermal lagoon in Iceland. Dating back to 1891, it is regarded as Iceland's oldest swimming pool, and that history gives the place a very different character from many of Iceland's newer geothermal spas.

Arriving at Secret Lagoon
When we arrived, we were welcomed by friendly staff who explained a few simple rules before we went inside. Towels were also available to rent if needed.
The changing facilities were modern and comfortable. After showering and changing into our swimwear, we headed outside for our first look at the lagoon.
Iceland's oldest natural hot spring pool, offering a charming, historic soak amidst active geysers.

The setting immediately felt natural.
The lagoon is surrounded by geothermal activity, with steam rising from the landscape and hot springs nearby. As we stepped into the warm water, we could actually feel the sand beneath our feet and between our toes.
That small detail stood out to us. Secret Lagoon doesn't feel like a perfectly polished modern spa pool — it still feels connected to the natural geothermal environment around it.
Hot Water, Champagne and a Very Relaxed Atmosphere
Once we were in the water, there wasn't much else to do except relax.
There is something special about sitting outside in naturally heated geothermal water in Iceland with a glass of champagne in your hand.
Looking around the lagoon, it was obvious that we weren't the only ones enjoying it. People were relaxing in the water, talking, having drinks and simply taking in the surroundings.
The atmosphere felt easy-going rather than formal, which suited the place perfectly.
Exploring the Geothermal Area
One of the things that makes Secret Lagoon different is what surrounds the pool.
The lagoon sits in an active geothermal area, with steam rising from the ground and natural hot springs just a short distance from the water. Instead of the geothermal landscape being hidden away, it feels like part of the experience.
After relaxing in the lagoon, we could take in the surroundings and see just how active the area really is.
More Than Just a Hot Spring
What we especially liked about Secret Lagoon was its simplicity.
It doesn't feel like it's trying to be a huge modern luxury spa. The warm water, sandy bottom, steam and geothermal surroundings are enough.
And then there is the history.
Knowing that Gamla Laugin dates back to 1891 gives the experience another dimension. Swimming lessons were held here from 1909, and the pool remained an important part of local swimming history before eventually falling out of regular use. It was later restored and reopened as Secret Lagoon in 2014.
So while you're relaxing in the water today, you're also sitting in a place with more than 130 years of Icelandic bathing history behind it.
Our Verdict
We really enjoyed our visit to Secret Lagoon.
For us, the combination of naturally hot water, the sandy bottom, the geothermal surroundings and the relaxed atmosphere worked extremely well.
Sitting in the warm water with a glass of champagne while steam rose around the lagoon was definitely one of the highlights.
But what makes Secret Lagoon particularly interesting is that there is a genuine story behind the place. This isn't simply another geothermal lagoon — it's Gamla Laugin, dating back to 1891 and regarded as Iceland's oldest swimming pool.
If you're travelling through the Golden Circle or South Iceland and want a geothermal experience that feels relaxed, natural and connected to Icelandic history, Secret Lagoon is an easy one for us to recommend.
