Drysuit Snorkeling Tour in Silfra

Based on 52 traveller reviews

Dive into this drysuit snorkelling tour of Silfra fissure in Þingvellir National Park, a UNESCO World Heritage Site. Located at the edge of Þingvallavatn, the largest natural lake in Iceland, this tour is sure to enthral and mesmerise you!

You'll have an unforgettable view down into the depths below, thanks to the silvery water which gives Silfra its name. The water is so clear, you'll be able to see as far as 100 m (almost 330 ft) down, to the shadowy caves that are formed by centuries of earthquakes widening the fissure and releasing the pressures of the earth's crust.

It's the only place on earth where you can swim between a meeting place of worlds - the North American and Eurasian tectonic plates. Witness the strength and power of the land as you drift on the current. Plants resembling troll hair grow on the rocks, floating in the water, and you'll see many shades of green and yellow algae.

Silfra was recently ranked #15 on the World's Best Dive Sites, chosen by CNN News. With this tour, you can experience the mysteries below without being a fully qualified diver, and make a fun afternoon of it while you enjoy the national park. There are also several walking trails around Silfra if you'll like to enjoy the scenery by the water.

Because you're wearing a drysuit, you'll view Silfra from the surface while the slow current carries you through a stunning underwater landscape. You stay dry underneath the drysuit, and you'll be warmer in the water, which is usually around 2–4 °C (36–39 °F).

It's so cold because it is meltwater from Langjökull glacier, filtered through porous lava rock for as much as 100 years before finally flowing into the fissure at the height of purity. Go ahead, take a sip!

Don't miss your chance for a refreshing dip in the purest water on earth! Check availability by choosing a date.

This was an amazing experience every bit worth the money. The view was spectacular and the drysuit kept you plenty warm. Heimir and Weston did an awesome job with our group I highly recommend this tour.

This was a great experience! Our guide Weston did a superb job of making us feel perfectly comfortable and safe - and let us enjoy and explore the fascinating crystal clear water! Do not hesitate - just sign up and you will not regret it!

This tour was one of the highlights of our trip. The guides were nice, friendly, and patient. The water wasn't as cold as I had anticipated and the view underwater was breathtaking. Bonus getting to drink fresh glacier water while snorkeling. I would recommend this tour to everyone!

The guides were very friendly but also professional! Thank goodness the sun came out. This is totally worth the money! The water is so clean and clear that we drank it (not on purpose, but we did :P)

Dry suit snorkeling with Adventure Vikings was amazing!! Brindi and Ari were so awesome helping us get into our dry suits (no easy feat...) and Heimir guided us through the water and was fantastic! We loved every minute of it. Other than my lips and face being a little cold in the beginning, I was very warm and comfortable in the water. It was incredible and the staff was great!!

My friends and I went snorkeling in the beginning of March. Before we go, we heard a lot about the freezing water. But actually we wore a lot under the dry suit when we were in the water. So only the face and hands where exposed in the water felt a little bit cold at first. The glacier water has three colors, and the view and experience in the water are soooo unique. And our guides are very patient and nice. They actually helped us a lot when we were stuck in the rocks. Will definitely recommend this tour and attend once more if there is a chance back to Iceland.

Amazing experience! The water in incredibly clear and your discover a world you couldn't imagine from above. I was a bit frightened to swim in a so cold water but everything went well. You feel the cold on your hands and on your face but it's ok. Very good guide!

Great experience, well organized even though it was very cold during preparation but no problem in the water. Would really recommend it!

Wonderful and unforgettable experience to swim in this lake! The 2 guides were so friendly, helpful and responsible. They took care of us very well. We drove yourself to the meeting point, which was very easy to find. The dry suit (and our warm undergarment) kept us warm despite a temperature of -3 outdoors. However, a little bit of water still comes into the gloves so our hands were really cold by the end of the snorkeling tour. In total, we stayed around 30 minutes in the water.

So much fun and Brindi was lovely and very helpful!

super good! Not so cold as i thought. The guider is really nice.

Amazing experience !! The 2 guides are really nice and patient guys to answer our questions. The drysuit of Adventure Box keep us really warm and dry. We are lucky to have good weather.

Absolutely amazing experience!!! Would definitely recommend this trip and experience to everyone. We decided to drive ourselves and meet the guides at the meeting point, which was very easy to find. The guides were great, very friendly and great to get to know. Water was extremely cold but the dry suites keeps us warm except for the parts of skin that were exposed. And getting to not only swim between the tectonic plates but also touch both was an experience of a life time.

Our snorkeling tour with Adventure Box was amazing! While cold, the water was incredibly clear and a lot of fun to be in. The views of the rift are worth every minute in the cold! We would definitely recommend this tour to anyone willing to brave the cold!

Just came back from the Silfra snorkeling tour with Adventure Box and highly recommend it! Floating between two continents is super cool and must-have experience in Iceland! The water is crystal clear and the underwater view is amazing! The water temperature is 2 degrees - it sounds very cold but I can tell you with my own experience it's actually not that cold, at least not as cold as you would expect it to be, if you are in a dry suit! ;-) I'm a person who is actually very afraid of cold and I was fine! Tips: get well-prepared - I put on two layers of sweaters and pants under the dry suit, all in wool, and I didn't feel very cold. The equipments they provided include shoes and socks and undergarments which also helped to keep you warm. I wouldn't recommend wet suit, though. I could imagine it must be cold if you don't wear anything under the suit. Also highly recommend the Adventure Box who delivered the tour very well and helped made the tour a perfect and unforgettable experience. Our guide Bjarki and Ari are very kind and responsible. It wasn't easy to put on every single piece of the equipment and they spent a lot of time helping everyone of us get well dressed before getting into water and double checked to make sure there's no water leak (at least I didn't get any leak ^ ^). Ali took special care of the few people who claimed to be poor swimmer, including myself, and had been very patient with us. He even took the trouble to take a man who failed to get into the water back there after the snorkeling is done (at his request) so that he could take a few pictures as his memory of the tour in Iceland (a huge favor, I think). Many thanks to Bjarki and Ari for making this tour a great memory! Xiaowu Sun

We recently booked a Silfra snorkel excursion with Adventure Box. We booked them through Guide to Iceland. The tour guide was on time and very helpful in explaining the excursion. Every single other tour group bailed, so we had the water to ourselves. It was very cold outside and windy. Colder than normal, hence all the other groups bailing. There was a chance our trip would be canceled due to the weather and the company was in great communication throughout. We had flown straight from the US and just had gotten off our flight to do this excursion. Our group was very tired, cranky, and cold. The guide did a great job with putting up with us and helping outfit us. Be sure to wear warm clothes under and great socks. You will be slightly cold but the views are worth it. Thank you Adventure box. Be sure to tip your guides because it is a lot of work helping put on the gear!

It was an amazing experience to swim between two continents. The water was very cold, but worth every minute.

Experience was amazing! Especially enjoyed the taste of fresh glacier water as we snorkelled around the lagoon. Our guide Wesley was really friendly and helpful. The actual guide and experience was great but we did have an unpleasant situation. Our bookings were not reflected with the actual guide operator so it was overbooked by Guide to Iceland. Although the actual guides gave us options to join the later tour, we wasted a few hours waiting in the cold and it disrupted the rest of our travel plans. It wasn't the fault of the actual tour guides but it was really not a good situation . For this reason, I've down rated this.
