The Secret Lagoon is a natural hot spring in South Iceland which is known to be the oldest swimming pool in Iceland.

Even though this lagoon is not as secret anymore as it was it is still one of the most natural and original lagoons in the south which is also offering some comfort. When talking about comfort I am talking about the possibility of buying drinks which you can enjoy like real Icelanders when bathing in the pool. The showers and locker rooms are modern and allow you to lock your important things like your purse and phone.

The hot water comes from the natural hot springs surrounding the pool. Even a little geyser is showing off every few minutes. But you can only bath in the swimming pool. All areas around are too hot to take a bath.

The ruin you can see from the pool used to be the old changing room. My boyfriend was still changing there when the lagoon was still secret and used by locals. This is actually not that long ago as we are not that old.

Like in many places in Iceland you are going to be asked to take off your shoes before entering the changing rooms. And you will be asked to shower naked before entering the pool. This might seem strange for some of you but we do that for hygiene reasons here in Iceland and men and women are not in the same changing rooms. So it is not that bad.

Insider Tip: After showering when you are rushing to the pool I would highly recommend to take your time (even though it might be very cold but I promise it will pay off) and look to your right (for women) or left (for men) as soon as you walk outside the door. There is a wooden box with floating items like you know it from kids when they are enjoying a playful swim. But now it is your turn! Take one, or even better, two floating items and take them with you into the water. This will allow you to float around the pool while enjoying your cool drinks.

On cold days I would also recommend to bring a hat with you as your head might cool down while bathing
