An unforgettable experience.

Needles to say, this experience is an absolute MUST. Don't be put off by the thought of the cold, because you really don't even notice it in the dry suit. The tour guides, Peter and Timos were remarkable. They were fun to talk with, and knew quite a lot about the locations. And I've got to say I really loved Peter's choice of music for the bus rides. Timos was really friendly, and took photos throughout the tour, all while giving out useful tips about the dive. He also helped me recover my lost watch! The views are remarkable, and I would do this again without thinking twice. You won't make a wrong choice booking this tour.

Þingvellir (Thingvellir)

A historical site, national park in Iceland and a UNESCO heritage site. Originally known for being the place where Alþingi (the parliament) was founded in 930 this place had served a grand role in Icelander's saga since the settlers came. Still today you can find ruins of old stone shelters, the lakes and the Lögberg e. Law Rock. The park sits on a rift valley caused by the separation of two continental plates, with rocky cliffs and fissures like the huge Almannagjá fault. In this separation sits the amazing Silfra fissure.

woman snorkeling at Silfra Fissure in Iceland

Enjoy an amazing snorkeling experience as you drift peacefully in the comfort of a warm drysuit accompanied by our highly skilled guides. Silfra, frequently rated as one of the world’s top ten dive sites, is located between the tectonic plates of Europe and America so you will be snorkeling in between them. This is an experience like no other and Silfra is the only place in the world where this can be done. 

Take your Icelandic geology exploration to another level as you explore the crystal clear glacial water that runs from Langjökull glacier about 50 km away, water that has been filtering through lava for 100-200 years. Touch the moving lava rocks and get a feel for the power and uniqueness of Icelandic nature in complete calm.  The visibility at Silfra is without comparison reaching somewhere around 150 meters. Some have described the feeling of snorkeling in Silfra like flying and others experience an ultimate state of meditation. Snorkeling in Silfra fissure is often called liquid meditation and you will understand why when you try it!

Silfra is truly a mesmerizing site and Into the Blue offers a relaxing but exotic trip in a highly unique and captivating environment. Whether you are an experienced snorkeler or a beginner this dive is an absolutely mesmerizing experience!

This was the most incredible experience! The water is so clear and pure -you can even drink it! Swimming amongst the mountains in the national park was mesmerising.

Peter was a wonderful guide - very calming and relaxed within what were of course very extreme conditions (cold!). He was very helpful, also driving well on the windy roads! His eclectic taste in music added to the road trip ‘vibe’ as we admired the beautiful scenery! Nick, Diego and the rest of the team were so lovely providing hot chocolate and biscuits!

Highly recommended although of course not for the faint hearted - as these are extreme conditions.

My wife and I thoroughly enjoyed this unique experience! We'd recommend it to anyone as an experience that cannot be had anywhere else in the world. Despite the crush their industry has suffered in the pandemic and the severe staffing shortages, they were efficient and 100% focused on providing the best experience possible; showing genuine joy in sharing the experience with us.

Wonderful Silfra snorkelling experience with Arctic Adventures

Reviewed on June 01, 2021 by Kai Kol Review from TripAdvisor

We went on the 3-hour Silfra Snorkelling tour with Arctic Adventures and had an absolutely great time. Two of us went on this trip and this was our favourite Icelandic tour by far!

Our guide, Halli, was informative and made sure we were enjoying our snorkelling experience while ensuring that we were safe the entire time. Both my friend and I were a bit scared to start off with because the snorkelling gear feels a bit tight, but with Halli's encouragement, we made the leap and ended up having a wonderful time exploring Silfra. We even had a hot chocolate to top off the adventure with, couldn't have asked for more!

I was also grateful for all the information provided prior to the trip regarding meeting, location, what to bring for the adventure, etc. It was very helpful in preparation for our trip.

Best Experience !!

Reviewed on March 12, 2020 by 8milicam Review from TripAdvisor

We visited Iceland in early March, and although it didn't look like that at first, the weather was extremely nice and sunny which provide a stunning and unforgettable experience when visiting around the island. In our visit to Icelad, what stood out the most to me was snorkeling in Silfra. I went there unready as it was my first encounter with something of that sort, and was therefore scared, as the temperature of the air was -4°C. Fortunately, after an encouraging speech from our instructor Nebo, everything started making more sense. For not one moment were we left unsupervised and without help of our instructor, and when it came to putting our snorkeling equipment on, Nebo was there to help and explain everything. We got a set of instructions before entering the water, and shortly after, the adventure began...
Nebo was next to us for the whole time, constantly checking if everyone is allright, whilst taking photographs of us, which came out great. The photographs will remain as a reminder of one of the better experiences i have had in my life. A big Thank You to our instructor, Nebo, who made all this possible.

The guides were very easy going and funny. They helped us all put our suites on and then they separated us into 3 groups, because each guide can only have 6 in the group. My guide was Matt and he was very attentive, and that is a good thing for me specially because I kinda freak out for a second twice and he would immediately realized it and asked me if I was okay and got closer so that made me feel so much better and confident to go on. In all the experience itself was amazing the view is unbelievable and didn't get cold at all, actually when you get out of the water you are warmer than before getting in which is strange but means their suits really work.

The guides will give you a warm suit and lateron help you to get into your drysuit. They do have a heated truck where you can change and that was actually very comfortable. Our guide Kevin gave us instructions and after that we walked to the platform. The views are amazing and although the water is icecold you stay comfortable warm except your hands and small part of the face. There were only 5 people in our group and Kevin was a very nice and funny guide. We also had lots of fun during the trip. The snorkling is breathtaking and it is a weird experience to ‘float’ in a drysuit. Afterwards you can change again in the truck and we got hot chocolate and cookies. It was an amazing experience!

We've just returned from a 5-day trip to Iceland. We had a great morning doing the snorkelling. Amazingly, the only things that got wet were my hair and my hands.You have a dry suit with a separate padded suit underneath (like an adult babygro!) gloves and a head cover. I expected to be really cold and it was quite a comfortable experience. Our guide was Kaldo. We were in a group of 4 people. Before we set off I was a little apprehensive. Our guide was incredibly patient and the whole trip was very professionally run. We had a large van to change into and toilets were available.
The water is crystal clear and I would definitely recommend doing this trip.

Awesome experience! Silfra Fissure Snorkelling.

We had a great snorkelling tour at Sifra. We started by getting a minibus to the site in the Thingvellir national park and then started to get kitted up in a warm under suit followed by the dry suit. After getting our Hoods, Gloves, Goggles and Snorkel we went through with the tour guide where we we're going and what we we're doing and it sounded amazing!

When we got down to the steps, the tour guide made us feel perfectly safe and our group (of 6) got into the icy cold (2 Degree!) water and then proceeded to snorkel to the exit point. The views under the water we're amazing and water was so clear with no silt to obscure the view. The colours under the water we're amazing and we had sunlight coming in to accentuate that!

Although it was cold (Snow was on the ground) Arctic Adventures had all the right gear with a "changing van" which had a constantly running heater to take the edge off a bit.

Overall the company is well run and makes the process fun and easy. Our guide led us on how to put on all of our gear, double checked that it was all on correctly and working properly. This allowed for maximum warmth and comfort. Our guide gave us excellent directions on what to expect and how to snorkel the fissure. His patience and knowledge allowed us all a unique but enjoyable and safe experience. When we were done, we were led back to our spot and removed all of our gear. Someone was always available if you had a question or needed and extra hand to tug on/off the dry suit. The hot chocolate and cookies were a nice touch.

Awesome tour!

My friend and I took the Arctic Adventures snorkeling tour in Silfra Fissure, and it was amazing. They outfit you with tools to keep you as warm and dry as possible. Our tour guide Steve was attentive and made sure we all felt good to go. He answered lots of questions about Iceland and was interested in where we were from and where we were going/what we had planned. He made the preparation for the tour fun and enjoyable! The water was clear as I've ever seen, and it was so cool to float down the fissure and marvel at the surroundings. I am SO GLAD we did this tour! Thanks!!

All relevant information for the tour can be found in our snorkelling handbook.

Yes, you can bring a camera, but we recommend to have a waterproof one if you want to have it in the water with you.

If you plan to drive and meet us on location, the meeting point is at the Silfra car park, in Thingvellir National Park.

GPS: 64°15’23.508″N 21°6’58.676″W

Note that the National Park charges a small parking fee of 500 ISK.

We kindly ask you to be at the Silfra car park 15 Minutes prior to your tour starts.

No. Unfortunately, glasses don’t create a seal between your face and the mask. We recommend wearing contact lenses instead.

You are not able to participate in the snorkelling tour if you are pregnant.

Yes, the tour is directed in English and therefore you need to be able to understand English to participate.

Some snorkelling tours match with a dive tour, and then you will be in the same area at the same time. You will, however, be in separate groups with separate guides, and won’t be in the water exactly at the same time.

You need to be more than 12 years old. Participants under the age of 18 must be accompanied by a parent or adult guardian booked on the same tour.

You need to know how to swim independently. Because of the dry suit sizes, there are height-weight limitations. The minimum height is 150 cm, and the minimum weight is 45 kg. The maximum height is 200 cm, and the maximum weight is 120 kg.

All participants must have read and followed directions in the Snorkeling in Silfra Handbook

When snorkelling in Iceland you will be wearing a dry suit, hood and gloves made of neoprene, along with fins, mask and snorkel. This equipment will make it not only possible but also very enjoyable, to stay in the water despite the low temperature. It is a fantastic experience.

No, you don’t need any previous experience to snorkel, but it is important that you can swim independently and that you are comfortable in the water.

Please wear or bring some long underwear and some warm socks. Wool or fleece is the best material to wear. You will be wearing your long underwear and warm socks under the dry suit.

We provide dry suits so that your body stays dry, and you will also wear undergarments to keep you warm. We use high-quality neoprene dry suits from Waterproof International and O´Three. But it is good to know that there is always a small risk that water can enter the dry suit. This is not dangerous but can feel a little cold, so we recommend you bring a spare set of clothes and a towel, just in case. Kindly note that your hands and face will get wet, which is completely normal and not actually that cold.

We provide an undergarment and neoprene dry suit from Waterproof and 0’Three. We also provide a neoprene hood and neoprene wet gloves to protect your head and hands from the cold. You will also be given fins, mask and snorkel.

Our client to guide ratio is one guide for every 6 snorkelers.

The water temperature is 2-4 degrees C (35-37 degrees F) all year round. The water comes from the Langjökull glacier which keeps it nice and cool, and very refreshing!

We use high quality neoprene dry suits from Waterproof International and O´Three.

Yes, there are 2 toilet facilities at Silfra. However, we don’t recommend that you use them for changing, as it can result in long queues.

Sometimes fish venture into Silfra from Þingvallavatn lake, but they will quickly swim back, as they don’t like chilly glacier waters. However, there is plenty of colorful seaweed, including a bright green variety known as “troll hair”, which makes the fissure unlike anything on the surface.

The cave systems in Silfra can be up to 60 m deep. However, your dive in Silfra will be from about 7 to 12 m, and the maximum diving depth that is permitted is 18 m.
