Silfra is a rift in the Earth between two tectonic plates. Swim in the gap between Europe and North America in crystal-clear water.

You will experience a truly breathtaking experience as you drift peacefully through the electric blue waters of the Silfra Fissure. The water is astonishingly clear because it is glacial water from the Langjökull Glacier.

All year-round, the temperature in Silfra is about 2-4 degrees, but don’t worry! We provide fully insulated dry suits, and there will be a certified expert with you at all times. The water in Silfra is as pure as water can get: meaning that you can drink it during the dive!

Snorkeling Silfra Near The Rocks In Iceland

Silfra is located in the heart of the historic Thingvellir National Park, a UNESCO World Heritage Site. The fissure opened after a strong earthquake in 1789. The North American and Eurasian tectonic plates continue to move farther apart at a rate of about 0.79 in (2 cm) every year.

To get to Silfra for your snorkeling trip, you can choose a pick-up from your selected location in Reykjavik. You may also choose to meet us on location at Thingvellir, where our friendly guides will be waiting for you.

The best part is that you don’t need any certification or previous snorkeling experience. The only requirements are that you’re healthy, adventurous, and able to swim!

Once you’re at Silfra, you’ll be given all the necessary equipment and put on your drysuit. You’ll swim in the “lazy current,” a stream of glacial water that flows slowly in the fissure. The pure glacial water filling the rift has been filtered by lava rock for decades, so feel free to take a sip of water while you’re there!

Marvel at the contrast between the deep blue water shades with the lime green and orange seaweed along with the dark brown rocks. You’ll discover spectacular rock formations as you glide through the four sections of Silfra:

  • Silfra Big Crack is the narrowest section, 394-feet (120 m) long, where the tectonic plates are incredibly close to each other.
  • Silfra Hall is 26-ft (8 m) wide and 46-ft (14 m) deep, with more light and massive rocks on the bottom.
  • Silfra Cathedral is 328-ft (100 m) long and 75-ft (23 m) deep, where swimming feels like flying.
  • Silfra Lagoon is the 16-ft (5 m) deep section with the best visibility and bright green algae.

When you finish snorkeling, you’ll be welcomed at the surface with cocoa and cookies to warm you up as you enjoy the panorama of Thingvellir. One more reason to add this experience to your bucket list!

Important note: Participants need to be comfortable in the water and be able to swim. You cannot participate if you are pregnant due to the small risk of cold water entering the suit.

If you are interested in photos please let your guide know before you go into the water and after the tour, the guide will provide you the code to the folder which includes all the photos from that day.

Kindly note that photos cannot be guaranteed. Our customers’ safety and well-being are our first priority, and therefore the guide will focus on snorkelers as a priority when in the water and will be taking photos when everyone is comfortable.

Unfortunately, you cannot wear glasses as the glasses don’t create a seal between your face and the mask. We recommend wearing contact lenses instead.

It is a magical experience. When snorkeling 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 as well very enjoyable to stay in the water despite the cold temperature. Tripadvisor recently rated Snorkeling at Silfra as one of the Top 5 travel experiences in the world. 

No, you do not need any previous experience to snorkel, however, it is important that you can swim independently and feel comfortable in the water.

We highly recommend long underwear and some warm socks. Wool or fleece is the best material to wear. You’ll be wearing the clothing under the dry suit.

We provide you with high-quality neoprene dry suit so that your body stays dry. There is always a small risk that water can enter the dry suit, that is not dangerous but you can feel a little cold, therefore, we recommend you to bring an extra spare set of clothes and a towel, just in case. Note that your hands and face will get wet, which is completely normal.

You will be provided with high-quality neoprene dry suit from Waterproof International and O’Three. As well as neoprene hood and gloves to protect your head and hands from the cold. You’ll also be given fins, mask, and snorkel.

Yes, there are two toilet facilities at Silfra.

Occasionally fish venture into Silfra from Þingvallavatn lake, but they will quickly swim back as they don’t like the cold glacier water. However, there is a lot of colorful seaweed including a bright green variety known as ‘’troll hair’’, which makes the fissure unlike anything on the surface.

Silfra can be up to 60m deep. However, when you’re diving in Silfra than you will go about 7 to 12m deep, and the maximum diving depth that is permitted is 18m.
