Snorkeling in Silfra (Þingvellir National Park)


Float between two continental plates in the bluest and clearest water you’ll ever see. A must do during your Iceland visit in any season.

You don’t need to be a certified diver to enjoy this amazing tour at Þingvellir National Park but you need to be comfortable in water and open to seeing something spectacular. We here at I Heart Reykjavík have done this tour and it was beautiful and completely worth the hassle of figuring out a dry suit

If you are worried about the cold you don’t need to be. You will be provided with warm insulation layer and a dry suit which, especially when paired with good thermal underwear, will keep you plenty warm.



Arrival in Þingvellir

Upon arrival, your guide will assist you with your dry suit and snorkeling equipment to ensure that you will be warm and comfortable during your tour. Each guide will take care of 8 snorkelers once in the water.

The Snorkeling Experience

During your snorkel you will explore the four main parts of Silfra: Big Crack, Silfra Hall, Silfra Cathedral and the Silfra Lagoon.

You will float through Big Crack, Silfra’s narrowest section and where the continental plates are so close you can almost touch them. The fissure then widens into Silfra Hall. Here the full spectrum of Silfra’s colours and clarity become all the more apparent. At this point, if you look at just the right angle you can see all the way to Thingvallavatn, over 150m away. Near to the opening to Thingvallavatn you will enter the Silfra Cathedral; as the depth reaches 23m you feel like you are flying over the boulders and glacial silt. Your snorkel will finish in the Silfra Lagoon.

Comments from previous guests

“Snorkeling Silfra”

Great experience with during a recent snorkeling trip to the Silfra Fissure. We were picked up at our hotel right on time and had an entertaining ride out to the snorkeling site. Our guides, Reynar and Michael, were friendly, funny and filled us in on lots of local info as we drive to the destination. Once we got to Silfra those process of suiting up began. It took well over an hour to get everyone in the group geared up - add to this that it was pouring rain - yet all the while Reynar and Michael worked diligently (ensuring that everyone was safely suited up) and kept the group laughing. The snorkeling was phenomenal (and yes, cold) but it is a once-in-a-lifetime experience we are glad to have had. Would highly recommend based on the professionalism and excellent attitudes of our guides.
“An Awesome Experience”

Coming to Iceland, I imagined doing numerous hikes, chilling in hot springs and photographing northern lights. I never thought I would go snorkelling, especially in winter. Having said that, I am so incredibly glad we got the chance to do it with and have Felix, Ted, Michál and Ásgeir as our instructors. They are truly an awesome bunch and extremely professional in their work. This was my first time snorkelling and I couldn't have asked for a more helpful staff. They made us all feel comfortable, explained everything in detail and we truly had a great time. Clear water, beautiful views, some hot chocolate to warm up and fun people around you - what else can you ask for?

“Iceland at its best”

So beautiful, raw nature, meditative and calm. Sure it was cold but that is no problem because this is definitely one of my best experiences I had in Iceland. Walking through snow to get to the water was also surreal. Thanks to Felix, Ted and Louis for there professionalism and true enjoyment of their job! Would recommend this activity to everyone.
