When you see the pictures and videos you might be thinking, how cold is Ice floating in Iceland? Not that cold! Ice Floating sounds a little crazy at first, but honestly, that’s part of the fun. When travellers hear about it, the first question is almost always how cold it really is.
Yes, the water is very cold. However, the ice floating experience in Iceland is far more comfortable and enjoyable than most people expect.
Ice floating is one of the newest and most unique adventures in Southeast Iceland. It combines glacier scenery, adrenaline, relaxation, and a little bit of bravery.
So, if you’re curious about what it actually feels like to float among icebergs in Iceland, here’s everything you need to know before taking the plunge.

What Is Ice Floating?
Ice floating is exactly what it sounds like. You suit up in a specially designed flotation suit and float peacefully in a glacier lagoon surrounded by floating icebergs, glacier views, and some of Iceland’s most dramatic scenery. At Fjallsárlón glacier lagoon, the experience takes place right at the edge of Vatnajökull glacier, Europe’s largest glacier.
This is not a swimming competition or an extreme survival challenge. We are talking about relaxing, enjoying the environment, and experiencing Icelandic nature in a completely different way.
Think of it as part adventure, part meditation, and part “I can’t believe I’m actually doing this.”And yes, you will definitely have a story to tell afterward.
So… How Cold Is The Water?
To know how cold is ice floating in Iceland, you need to know that the water at Fjallsárlón is cold, so let’s not pretend otherwise. The water at Fjallsárlón comes directly from melting glacier ice, which means temperatures are typically just above freezing year-round.
Usually, the water temperature is somewhere around 35–39°F (2–4°C). That sounds intense because, well, it is cold. The important part is that you are not entering the lagoon in regular clothing or swimwear. The specialized floating suits are designed for cold-water conditions and make a massive difference in the experience.
Most guests are surprised by how comfortable they remain once they are suited up properly.

The Secret is in the Floating Suit!
The flotation suits used during ice floating in Iceland are built to keep you insulated, warm, buoyant, and safe. They are thick, waterproof survival-style suits that trap heat while preventing the icy water from reaching your body. Once zipped into the suit, only a small part of your face is exposed to the cold air.
Even travelers who are not strong swimmers can usually participate comfortably because the suit does most of the floating for you.

What Does It Feel Like?
The initial moment of entering the lagoon can feel shocking simply because your brain knows you are stepping into glacier water. However, once you settle in and begin floating, the suit does most of the work. Instead of shivering, you usually end up focusing on the scenery around you, which is distracting in the best possible way.
Most people describe the sensation as:
- Cold at first
- Surprisingly comfortable after a few minutes
- Peaceful and relaxing
- Slightly surreal

Is Ice Floating Safe?
It most certainly is when done with experienced guides and proper equipment. Safety is always the top priority. The guides also remain nearby throughout the experience to assist and ensure everyone feels comfortable.
Before entering the lagoon, guides provide full instructions on:
- How the suits work
- How to move in the water
- What to expect during the experience
- Safety procedures and guidelines
What Should You Wear For Ice Floating?
One of the best things about ice floating in Iceland is that you do not need specialized outdoor gear to enjoy it. However, dressing properly underneath the flotation suit does help. Even though the suit is waterproof, Icelandic weather can change quickly, so dressing warmly before and after the activity is always a good idea.
Recommended clothing:
- Warm base layers
- Comfortable outdoor clothing
- Wool or thermal socks
- Gloves and a warm hat
- Layers suitable for Icelandic weather
You’ll want to avoid:
- Bulky clothing that restricts movement
