Snorkeling in a fissure caused by two tectonic plates drifting apart is something you can't do everyday! Silfra is the name of a big 'crack' stretching parallel to the North American and a micro-plate called Hreppar that broken off from the Eurasian plate.
Silfra has world-renowned clear and drinkable water with over 100 metre visibility daily. This is unlike any tour you can do in Iceland and is something you can't do anywhere else in the world.
We are the only company to offer wetsuit and drysuit. This means members of your group can book different options and still be together in the water.
We include photos and usually take around 40-100 photos as standard depending on the size of the tour and you will be able to download them after at least a few days.
We always have small groups, 6 people per guide. This allows for a better and more personal feel. If you have a group of 7 or more you can be together preparing your equipment but in the water some of you will be separate.

The location of Silfra, where the snorkeling takes place, is within Thingvellir National park. Passengers, while driving through, get a chance to view some of the beautiful nature the national park has to offer.
Heading out from your Reykjavík accommodation to Silfra takes about 45 minutes. After greeting your certified guide upon arrival, you'll gear up, listen to a safety overview, and head into the glacially flooded fissure known as Silfra. You'll spend around 30–40 minutes in the water before exiting and walking back around 5 minutes walk. You'll then get a chance of warming up with a well earned hot chocolate. We’ll take photos during the snorkeling. Typically 40–100 images, depending on group size and skill level. The photos will be available for download a few days later free of charge. For the drysuit option, Please bring your own one thermal base-layer. We recommend bringing thick (preferably wool) socks to help keep your feet warm while snorkeling. We’re the only company offering both wetsuit and drysuit options. This means members of your group can book in wetsuits or drysuits and you will still be in the same group in the water.

Kaya was our guide, she was great. My son had a great time snorkeling. I would recommend to everyone.

The snorkeling experience was fantastic! The guides got us kitted out and took tons of pictures. The problem was getting back to Reykjavik. Instead o our original guide taking us back we were told to wait in the parking lot and another driver would arrive in about 1/2 an hour. He arrived more than an hour later and it required us walking back to the snorkeling site (about 5 min each way) to get our original driver to call him. Meanwhile we are freezing in the pouring rain the entire time. It could have been organized so much better.

100000% recommend this tour! 🤿💙 Snorkeling between two tectonic plates in Silfra was one of the highlights of our Iceland honeymoon! I was equal parts excited and terrified, but once we got in the water, it was incredible. The hardest part was squeezing into the dry suit. 😂 Our guide, Dory, was amazing—sassy, fun, knowledgeable, and made us feel safe the entire time. We wrapped up the adventure by me getting yelled at by some birds 🤣 and warming up with hot chocolate. If you get Dory as your guide, you’re in for an unforgettable experience! 🇮🇸

We enjoyed this experience so much! Kaya was a perfect guide - always felt safe. The process of getting ready to get in the water is strenuous, but worth it. Remarkably, the only part of me to get cold was my face. But after a couple minutes, you adjust. Spectacular views and it was also unique to be able to take a drink of the water.

Kaya was an incredible guide. As someone who had only been snorkeling 1 time previous, I was a little nervous. Especially with the water being 2°! But Kaya explained everything clearly, made sure everyone in our group was confident, and lead us on a truly amazing experience. The water is SO clear. It’s almost impossible to comprehend. I can’t wait to see our pictures later on! I would definitely recommend this experience and this guide group to friends or family traveling to Iceland. Technical notes: We did the drysuit option. Make sure to have your own under-layer and warm socks. Wr bought ours in Reykjavik but it’s very $$$ here so if you can plan ahead, do so :). They provide everything else. One other note: the suit is very tight around the wrists and neck. People who have anxiety around this kind of construction should take this into account as they make their plans.
