Iceland: Snorkeling Silfra with – Swimming in Glacier Water between Tectonic Plates.

“You’ll be in the water for about 30-40mins… trust me, that’s enough… you’ll be begging to get out”

It was a drizzly Thursday in Þingvellir National Park, South Iceland, and I was about to be plunged into water that sits just above freezing. Horrendous? Potentially. But I was here by choice, joining to snorkel ‘Silfra’; the mid-Atlantic ridge, in glacier water filtered through rocks from nearby Langjökull, between the Eurasion and North American tectonic plates.
I was promised some of the clearest water in the world, crazy underwater scenery and a totally unique experience that you can’t have anywhere else in the world… But they weren’t beating around the bush about just how cold it was going to be. SO cold!

Getting Ready To Snorkel: An Adventure In Itself!

After our de-brief, we were sent over to the changing tables. Getting Silfra-ready was an experience in itself! Having been diving, rafting, and canyoning before, I was totally used to the pain-in-the-arse effort it takes to wriggle and stuff yourself into a sloppy tight wet suit. Dry suits though? Whoooole other ball game.

We had been told to prepare with thermals and woolen socks, but also provided us with additional insulation in form of these adult romper suits; like a sleeping bags with arms and legs. Wasn’t going to win any fashion awards with it, but these things were utter genius! I need to trawl Amazon for one, too perfect for lazy winter not-leaving-the-house-days!

After the cozy onesie came the epic battle to get into the dry suit, which was like a wellington boot for the whole body. Fun!
Thighs and bum were the two areas which were fighting against the whole notion of me getting into this thing. Half a heart attack later, a lot of puffing, and more than a little help from the instructors, I was properly stuffed into the suit, zipped up, struggling to breathe and getting used to the lack of circulation in my wrists… all part of the experience!

Next came the neoprene gloves, dry suit hood, mask, flippers and to top it off, a neck strap (yes, a neck strap!) to seal any pesky gaps between the suit and your body. Feeling pretty uncomfortable, a little spaced out and thinking that this must be pretty close to how astronauts react to being in their moon-suits, our group waddled the short distance to the edge of Silfra.

Finally after a few more minutes of last minute prep (“spit in your goggles!”) and another warning “guys… it IS going to be really cold…”, we were then given access to explore the bright ultramarine underwater world of Silfra…

The Underwater Wonderland of Silfra

Seriously… when they say it’s unique, there really isn’t anything quite like this on earth.

But cold, oh so seriously cold!

My specially designed underwater ‘adventure proof, shock proof, temperature proof, you-name-it-proof’ camera conked out within seconds of it being in the water, so to give you a pretty damn good idea of what I saw, I have featured’s photographs instead (all credit to them!). That startling bright blue water, those neon green algae, those musty orange rocks? All totally true to life and positively breathtaking.


After a few minutes my index finger and thumb decided they couldn’t take much more, and before long I’d totally lost all sensation in them, but with views that were out of this world, it was quite easy to be distracted from the discomfort.

The hardest thing was trying to direct yourself. To make any attempt at trying to swim anywhere, change direction or look behind you resulted in you looking like a floating weeble, bobbing along with legs and arms popping up at crazy angles; the dry suit was ultra-buoyant, and it was quite a strange thing to get used to.
“Relax! Take your time, and just float along!” our instructor encouraged.
She was right, in the end, it was easier just to loosen up and let Silfra take you, like the coldest lazy river there ever was.



Before long, we’d reached the end of Silfra (just before my fingers were about to drop off, i’m sure!).
But honestly. Mind blowing. Indescribable.
It was completely crazy to be able to swim in this water that was almost as clear as air and witness a section of the earth that is ripping apart by a few centimeters year on year.
I think that’s what I love most about this country, Iceland reveals our planet as this vulnerable, ever changing, unpredictable, active ball of lava and rock… simultaneously showing us how perfectly natural and crazily weird our world is.

It’s awesome.

  1. When I did it, my swimsuit took water and I nearly suffered from hypothermia. The experience was great though but I only managed to do one dive instead of 2, I was too cold (it was in December).


  2. This is truly a unique experience: ice water snorkeling between the tectonic plates! Dive.Is is an excellent group — they were well organized, attentive to the individual needs of the snorkelers, and serious about keeping everyone warm and dry. It took about an hour to get into the dry suits ! Our guide, Stephan was excellent — knowing in advance…

  3. This looks incredible but I’m cold just reading this. I’m visiting in December – I imagine it’ll be too cold to do the dive then?

    1. I would have thought it would be just as cold all year round to be honest, considering that it was around 2 degrees when I went 🙂 The dry suit keeps the water out, so it keeps you pretty much warm, apart from my fingers which were crazy cold! They get you to pour hot water in the gloves first before you put them on so it warms your fingers. The whole swim is about 30mins long, so it’s true when they say you won’t want any longer BUT honestly? It’s worth putting up with the chilliness of the water to see what you see! It would be lovely in the water with snow all around you!

      1. Hmm you are tempting me – I’ll propose it to my travel buddies and see what they think!


  4. Great! I was looking for some advice to do this dive in May next year. I’m comfortable in water but, I’ve never done a dive. Would you recommend experience with this or do they cater to the curious tourist?


    1. Is it the dive or the snorkel you are looking at, just to check? I snorkelled with 4 of my friends in the group , I had snorkelled before but one of our group had barely ever been in water before let alone snorkelled! He didn’t struggle, so yes, they cater for anyone – experience or no experience! Not sure if that’s the same for the dive… I’d send them a quick email to check! I emailed them before hand with loads of questions and they were super friendly and helpful with everything!
      I hope you do it! You won’t regret it!!
