Icelandic nature boasts a series of never-ending wonders that simply can’t be missed! Silfra is located in a UNESCO World Heritage Site and more than merits its spot as one of the top dive locations in the world.
Silfra’s unique natural history, incredible location in Thingvellir, and unbelievable electric-blue waters make it the best snorkeling location in the world.
Where else can you swim between continents and see the epic landscape created by two moving tectonic plates? Combine that with the chance to explore ancient lava tube caves formed thousands of years ago by volcanic eruptions. Now you have a life-changing tour that guarantees an amazing experience!

Your tour will begin when you’re picked up from your selected location in Reykjavik. The volcanic landscape of Iceland is rich in lava tube caves that have formed as a result of eruptions over the millennia. We start out at Raufarholshellir volcanic cave just a short drive from Reykjavik.
The ancient lava flows have created incredible formations and unique patterns in the rock. In winter, you can also see the glistening naturally-formed ice sculptures that contrast with the dark stalagmites, stalactites, and other formations.
The 1360-m (4500-ft) long Raufarholshellir is Iceland's third-largest lava tube.
Hiking in this otherworldly lava tunnel is not considered difficult. However, be aware that in some places you might have to get down on hands and knees or duck your head. But don’t worry, there will be plenty of open spaces to take outstanding pictures too!
After the cave exploration, you’ll have time to grab lunch before moving onto the second part of your adventure. Prepare for snorkeling in Iceland’s cherished natural wonder!

For part two of this trip, we go to Thingvellir National park for some snorkeling action in the Silfra Fissure. This rift between the North American and Eurasian tectonic plates is famous for the clearest water on Earth. It’s a must-do for anyone seeking a different kind of snorkeling or diving tour. The visibility in Silfra reaches beyond 100 meters, and there is plenty to admire down there!
Float weightlessly above the rift. Find yourself surrounded by vivid shades of blue, interrupted by the sun rays as they slice through the underwater canyon. Marvel at the bronze walls of the fracture and touch the green algae as you swim.
The meltwaters originate at Langjökull Glacier and are filtered over decades by porous lava rocks. There’s no harm in taking a sip of the pristine glacial water while you’re there!
Before we head back to Reykjavik, we’ll take a quick moment to enjoy the spectacular view of Thingvellir along with some hot chocolate and cookies.
Pick-up will begin at 8 a.m. from your hotel or nearby meeting point in Reykjavik. Please be aware that picking everyone up can take up to 30 minutes. Your patience is greatly appreciated. You can find a list of all available pick-up points in Rey...)

We booked the black and blue tour with arctic adventures. They were really friendly, punctual and we really enjoyed our tour! Thank you so much for creating memories we will keep forever.

My husband and I did the Black and Blue trip firstly doing the caving which was informative and well guided. In the afternoon we did the snorkeling at Silfra, now this was one of the reasons we came to Iceland and were not disappointed. The weather was cold and windy and we were concerned that we would freeze but I have to say I was at my warmest while being outside when I was in that dry suit! Entertaining getting in it but all the same warm. Your hands do get cold but as advised by the instructor just keep them still and it's not that bad. Highly recommend.

The Black and Blue Tour was incredible! Starting off at the cave and going underground is something I’ve never done before and it was so cool. Then we went snorkeling which was truly remarkable. Being between the tectonic plates is something you can only experience here so it is really a once in a lifetime experience. Steve was our snorkeling instructor and was amazing. He answered all questions and remembered each of our names in our small group and was very knowledgeable about snorkeling and the area. The hot chocolate and cookies at the end was a sweet treat! I would recommend this to everyone I know that visits Iceland because it was so incredible.
Still got questions about the tour? Hopefully you will find the answer here.
No, you don’t need any prior snorkeling experience. However, you’re required to know how to swim and be comfortable in the water in order to snorkel in Silfra.
Yes, you should be able to swim independently and feel comfortable in the water. However, you don’t have to be a strong swimmer to enjoy snorkeling in Silfra. If you know the basics, you’re good to go!
Yes, the requirements are as follows:
We recommend wearing a thin thermal base layer and warm socks. Materials like wool, fleece, or synthetics work best. The main goal is to wear something that will keep you warm. Cotton is not recommended.
We provide you with two layers of clothing: a thermal undersuit and a neoprene dry suit. We also provide you with a mask, a snorkel, fins, a wetsuit hood, and wetsuit gloves.
We use top-notch dry suits made by Waterproof or 0´Three, we’ll do our best to find the best fit for you. There is still a small chance that some water can enter your dry suit. Don’t worry, it's not dangerous but it will feel a little cold.
Just to be safe, we recommend bringing a change of clothes and a towel. While you’re snorkeling, your face, hair, and hands will get wet, but that’s normal and shouldn’t make you too cold.
Typically, we spend about 30-45 minutes snorkeling in the Silfra Fissure. After we finish our route, you can choose to either get out of the water or swim around a bit longer and explore the Silfra Lagoon.
